Having a mare sourcing parts for various projects. Project 1 I need an inline fuse holder, cartridge style not blade type, one that isn't pre wired, will accept 12 or 14AWG wire, for use at 12v with a 6A fuse maybe 6.3x32mm size You would have thought it would be a simple thing to source and buy. No, make no mistake there is lots and lots to choose from. None of them meet the simple requirement I'm looking for. I did find a littelfuse one at Farnell... £15.95 surcharge because it's shipped specially from the US warehouse. And it has a weird locking arrangement, just use a bayonet style like everyone else. Project 2 I need a pair of current limiting resistors (through hole) for a sealed lead acid charger project. Required resistance works out at 1.75ohm, but 1.8ohm is going to be the nearest standard value. So, 1.8ohm, 1/4W, Metal film. simples yes?.. no. RS - No Farnell - No CPC - no Mouser yes... but £12 delivery... for 2 resistors Digikey - Yes, but similar problem to Mouser and minimum order of about 5,000 Ebay yes... but they probably have leads thinner a human hair, and a temperature coeffiecient of who knows what. That's assuming they are within any sort of value tolerance to start with. Project 3 Don't even get me started on the various (through hole) ceramic capacitors I'm trying to source which includes (but not limited to) B471k 500v Various value, 50/100v, N0G (underscore plus black tip) 222 500v 102 500v 104 391 500v A "TA 820 J" marked SMD part that I still haven't 100% identified. Possibly a capacitor Maybe things are easier to source in the USA, it's proving frustratingly difficult in the UK though |

There is so much going on in the USA that parts are commodities. One can get nearly anything due to the size and volume. I may have some of the parts you need. There is a class of resistor called flameproof that may well be what you can use for the 1.8 Ohm; I likely have something close. I'm sure I have 2.2 and 1.5 for instance. They may be 2 Watt. In my trove of fuses and fuseholders I may well have what you seek but of course I am in California and shipping cost is daunting. Most of my stuff is for the 1/4"x1-1/8" like 3AG. The capacitors don't seem to be so unusual. Disc ceramic for instance. Don't you have any retail parts houses? I have All Electronics near me, and a little place called LC Electronics is even closer. Ebay has stuff too. |

I think things like this are much more readily available in the USA than the UK. I can't think of any high street stores now that stock or can source electronic components. It would be nice if we had places like all electronics, I bought a kit from them a little while ago. A friend of mine in Australia bought it from a store locally and posted it to me in a jiffy bag. Saved quite a bit on the shipping. Mostly it's online places for us RS, Farnell, CPC, Digikey etc and to be fair they are mostly pretty good. I'm just finding it a bit frustrating at the moment trying to find what I'm after. I have small but growing stock of parts. |

The capacitors aren't especially unusual, which makes it all the more frustrating. Out of all the thousands of parts RS stock, do you know how many C0G/NP0, 50/100v, through hole ceramic capacitors they have ? ....... 3 I'm not kidding, see screenshot attached! I know they can't stock everything in the history of the world, but it does make it frustrating when you are after a specific value part. |

Some distributors are more conservative than others. If you can import from Germany, Reichelt is giving me 29 C0G/NPO "wired" parts. (The search may be a little slow loading.) |
