Beginner shopping list of ic, diode, transistor
« on: April 10, 2015, 12:39:18 am »
Hello,

I bought some cheap sets of passive components and I'm looking now for active components.
I've already done some electronics when I was a teenager and some components came back to my mind:
- NE555
- 1N2222
- BC547
- some zener diodes

I'm looking for example for some references of :
- amplificator for general signal ( < 12V ?)
- transistors
- diodes
- common ICs
- other components which may be of use for a beginner

Could you help me complete my beginner set of components ?

Thanks

The component selection you should keep in stock is highly dependent on which branches of the hobby you are interested in.

Analog electronics:
    Audio
    Radio
    Control and sensing systems (e.g. temperature, light, etc.)

Digital Electronics:
     Logic (hard wired)
     Microcontrollers (e.g PIC, AVR etc.)

There are other more specialised areas, but they are far less accessible to beginners.

You will probably need a few OPAMPs, and various diodes, LEDs etc. anyway, but even for a basic OPAMP, you need to consider the application. e.g. if it is going to be used for microcontroller interfacing it may need to run from 5V single supply, but if you are using it in an audio application, one suitable for +/-9V or even higher split supplies may be needed.

Jameco has assortments of various components, you can get resistors, transistors, ICs, ect in a package. they come with a cabinet or you can oder them without the cabinet (refill package)....
Example: 420 Piece Diode and Rectifier Kit

Kit includes a 20 Drawer Component Cabinet (P/N 319600), 20 clear plastic drawers (P/N 319601), 20 clear dividers (P/N 319611), 30 adhesive labels for drawers to identify parts in kit, and all the Electronic Components listed in each kit .

Includes 15 types of zener-switching and silicon rectifiers:
10 of each: 1N270, 1N751A, 1N4001, 1N4007, 1N4150, 1N4733A, 1N4735A, 1N4742A, 1N5404, 1N5408, C106B1, KBP04M
100 of each: 1N914, 1N4004, 1N4148
For a 420-piece refill transistor kit without the component cabinet: (P/N 130366)

and also grab bags...I think the resistor GB has like 1000 pieces for about 8$, but no control over what you get.

https://www.jameco.com/webapp/wcs/stores/servlet/StoreCatalogDrillDownView?langId=-1&storeId=10001&catalogId=10001&categoryName=cat_10&subCategoryName=ICs%20%26%20Semiconductors%20%2F%20Assortments&category=1010&refine=1&position=1&history=majwk5l3%7Ccategory~10%5EcategoryName~category_root%5EsubCategoryName~ICs%2B%2526%2BSemiconductors

I find it the easiest way to stock up for somewhat cheap....and you can always order more (precision, name brand, whatever) components if you need them.....
My 2 cents......

Bunch of GP NPNs. I use BC337s as they will also drive up to 800mA without exploding. Bought a hundred off eBay for virtually nothing. Few PNP equivalents as well. Couple of JFETs.

Bunch of zeners. 1.3W. Different breakdown voltages.

Bunch of silicon diodes. 4002s are prob fine.

Some 1N4148s. Very useful.

Some comparators (393s), opamps that handle virtual ground/single rail (324s/one of the OPA series), 555s of course (stupidly useful and bend to things they weren't designed to do), linear regulators (317). All dead simple old stuff.

Tend to buy a pile of 4000 logic as well as its a little more voltage tolerant. Although I tend to wait until a whole box full of surplus stuff turns up for that. No idea what parts I keep in stock but I tend to use NOR, NAND, counters and not much else.

You can get away without much stuff if you know what you're doing. This is the art side of it.

The only thing I never have enough of is PCB mount terminal blocks and 0.5W resistors.

For audio, probably worth looking at an amplifier IC I.e. LM386 for bottom end and TDA/LM audio amps for high end. I've got an LM1875 amp on the living room table I'm working on. Nice IC.

I wouldn't bother with any logic family older than 74HCxx and Atmel MCUs (or any other specific brand)  aren't much use unless you have the ability to program them, (Knowledge, programming hardware, and software toolchain).   

* 1N4148 small signal diodes - for when a 1N400x is too big.
* BAT43 small signal Schottky diodes - for when a silicon diode has too high a Vf

Either you have to spend a serious amount of money or do not bother at all with stocking up on components.
I would suggest against it, because there is allways something missing you need and then you have to order annyway.
Order a bunch more of the stuff you will need for the project you are working on and use the surplus later.

What you could get is a decent resistor and capacitor selection, everything else depends on what you are dooing.
I have a bunch of opamps, transistors, leds and mikroconrollers that i mostly use.
You may not be in need at all for opamps...

Someone once told me, if you need 2 components for a project, buy 10 of those :P

There's often a price break at a quantity 10 pieces and at 100, etc. So if you buy 10 you basically get one free. I was actually working on an order this morning and I'm almost out of 4148 diodes. To buy just one is 7 cents, 10 was 5 cents each, but for a hundred they're less than 2 cents each. So I'm getting 100.

Define your project. Define the components necessary for that project. Don't forget the "ancilliary" components such as decoupling capacitors, wires, connectors ...

Guess what mistakes you might make (or think you have made) and what you will do to check/rectify the mistake. Add those components to the list (e.g. resistors that are 2* and 10* the values you think you need).

If using SMD components, assume 50% of them will suddenly disappear from your workspace, never to be seen again.

Make a note of minimum order quantities and postage.

Presuming it only takes a few days for components to arrive, it probably isn't worth stocking up on a wide range of "random" components.




There are lies, damned lies, statistics - and ADC/DAC specs.
Glider pilot's aphorism: "there is no substitute for span". Retort: "There is a substitute: skill+imagination. But you can buy span".

Sorry for my late response, I had some internet issues.

Thanks for your help, I now have a more clear view of what to get. The posts linked by mariush have informations interesting to make your decision. Sorry I haven't found them with the search function (and so mariush keep linking them again and again, facepalm).

I must have defined what I plan to do. I'm a computer engineer and some months ago, I came across a conf talk about Arduino. Arduino is way more simple to get to µController programming than 20 years ago (and way cheaper btw). That made want to come back to electronics. Budget is not much of an issue in my case because I'm a freelance and thanks to the Internet of Things buzz, I can now justify that my electronics spendings are for my R&D.

So I want mostly to do circuits around arduino programming (and PIC, STM32 in the future). My current plan is to do :
  • a small, cheap function generator (I don't intend to do RF)
  • a weather station with zingbee outdoor modules
  • a reflow convection oven with PID and the PWM with zero-crossing detection to drive a solid state relay
  • µControlled power strip for Raspberry Pi cluster with power monitoring and start/stop control
  • converting a CD jukebox to a BluRay data jukebox
  • CMS resistor decade (that's the easy one in my list)
  • µPower Supply if Dave advance on this one

But I also want to experiment with analog things because that will be needed if I want to use sensors and don't want to be limited to arduino sensors boards. That's why I asked for generic AOP and such, to do some breadboard experiments to learn how to use them. And that is also IMHO the way to learn electronics and not just plug things in an arduino socket.

And for that, I needed PTH component to put on a breadboard. But when I'll get to the point of baking my own board, I want to use CMS components, because they are prettier and I want to learn other things that those I have already done as a teenager. So if I need a specific component, I'll buy several of them as CMS and use adaptor boards to use them on a breadboard.

I bought a set of ~1000 different CMS components from ebay with lots of 74HC as well as some other things like RS232 chips, EEPROM, ... That was probably a surplus from a military or medical project because there some components refs pointed to non ROHS versions and the resistors were 0,5% precision (5 differents values measured between 0,1% and 0,25%). Other analog IC I got in this set are rather for specialized use like the TLC2264IRD. And I prefer to use them later when I know when they will be worth it rather than frying them for free. So on the digital side, I have much of all I would want in CMS and will use adaptor board for them if I need them.

In conclusion, I need only a limited set of analog basic PTH components to start.

I finally came to this list :

Diode
1N4007 : not necessary to bother with previous 1N400x versions and it could also be used to make a diode gate
1N4148 : for signal use
BAT43
A kit of zener Zeners
A kit of LEDs

BJT Transistor
2N2222 : preferred over BC337 as it seem to have a better spec
2N2907 : its PNP friend

MOSFET Transistor
BS270

JFET Transistor
2N7002 : I took the cheapest one available, just to have a JFET to toy with

Comparator
LM339

AOP
LM324

ICs
NE555
74HC595

Power supply
7803, 7805, 7812 and 7912
LM317

Thanks all for your help.

On that JFET, I believe the 2N7002 is a SMD component. Maybe that's what you intend. However, the 2N7000 would be the through-hole version.

If everyone tries to nitpick we will be here till the sun explodes, but i will do annyway :-P

MOSFET Transistor
BS270

AOP
LM324

ICs
NE555
74HC595

When you allready want to work with cheap micros, you might not have a need for a NE555.
The 74HC595 is somewhat handy, pairs well with a ULN2803 for higher power.
But could be replaced by a more modern, although more costly, I2C/SPI port expander.

The R2R and lower voltage version of the LM324 is the LMV324 if you need that.

The BS270 is an N-Mosfet, you should get a few P-Channel as well.
The 10V Vgs are not that great either and it has a terrible RDS-ON.

Think of adding adjustable potentiometers, classical and 10 turns. And also some electro mechanical components, such as small relays, push buttons and rotary encoders. It is also very usefull to have at least a LCD display such as the 1602, or even a LCD touch display. All these components allow interaction with the microcontrollers !
