What's this please? (Component Advice)

[fluxcapacitor]

I am thinking it's a regulator, part that says GGRTW which I can't find on google.

What is the pcb from ? + model name/number on pcb etc .

[Alexei.Polkhanov]

Wow, lovely sensors they have - MS5805 includes 24 DAC with 15 cm altitude resolution. :-)

Ok so this component is a capacitor I am pretty sure of that, however I have no idea what type of capacitor. Doesn't look like any electrolytic or ceramic capacitor I have ever seen.

It is a polyester film capacitor mostly (if not exclusively) made by EPCOS.

[Alexei.Polkhanov]

Yes very much like it. I wonder who painted the sides with blue paint?

[fluxcapacitor]

Theres some datasheets here:

http://www.epcos.com/web/generator/Web/Sections/ProductCatalog/Capacitors/FilmCapacitors/MetallizedPolyester/Page,locale=en.html

The caps are ,radial Boxed,radial uncoated ,radial coated etc and a note in one the datasheets about mounting -

Notes on mounting
When mounting these capacitors, take into account creepage distances and clearances to
adjacent live parts. The insulating strength of the cut surfaces to other live parts of the circuit is
1.5 times the capacitors rated DC voltage, but is always at least 300 V DC.

That could be why theyve been "painted"  ?

[SeanB]

The painting is just the "extra protected" version. Those generally are nice capacitors, and are made on a large wheel and then cut to size before final lead attachment.

What are the components in the metallic packages? I never noticed them before.

The packages look like oscillators. But the components are used in power supply related context (big inductors and caps), which I think eliminates that possibility. What else? Fancy caps? Tiny transformers?

Ok, I think I figured it out: International Rectifier DirectFET MOSFETs

Hi can anybody tell me what these parts are soldered to the legs of this to92?
Have no idea what they might be called

They look like PCB Turrets to me

[notsob]

Test points, there are a quite a few to choose from, here are some examples

Guess what is this

A TV Tuner?  Wow!

Actually a wide-band low-noise amplifier, core component for this project:

[PA0PBZ]

Oh! Oh! May I?

The hand drawn part is the rough copy of the silk screen that was under the component. Basically a zigzag in a rectangle. Probably some power component, but I have never seen the symbol, so no idea.

EDIT: added a picture with a ruler. It's about 10mm wide.

What happened to your photos?

My guess: after 2.5 years most bits are recycled and used somewhere else on the 'net?

To me it looks like they are crimped to the to92's legs so i'd say they are contacts for a twist socket like the ones on a fluorescent lamp starter .

I guess the to92 part is a temperature sensor .

Hi,

It's a inductorless SR IC. Its powered from the mains (110/240 V ac). Ok, I know what it is, but i can not identify the part number on the IC. I wonder if someone can identify the IC based on the traces on the pcb. I don't have a better picture of it. It's from the "Moteino"  website.

Thanks.
 

[fluxcapacitor]

the picture isnt clear enough.

According to the guy, it's a Supertex SR-086 Inductorless Switching Regulator.

Hi!

Can someone confirm whether this is a quad positioning sensor or something else?

Appreciate all input!

Thanks

[SeanB]

Uncased 4 quadrant large area photodiode definitely.

[edwardcurrentclamps]

Thanks,

any idea where I get something like that? I also wondered, how are you so sure. In what kind of application have you seen something like that before?

Thanks
