I've had several projects which I've put away for a while and decided to complete now and am wondering which components I can continue to use and which ones I need to re-purchase. The components are probably 10-30 years old (from purchase date).
Some components have been desoldered from poor PCBs (I'm re-etching the boards) and some are still in my component boxes, not soldered into anything since purchase.
I've heard that electrolytic capacitors dry up, so I assume none of these should be re-used (desoldered or completely unused) because of their age), but how about these?:
- resistors
- potmeters and trimpots
- ICs
- transistors
- diodes
- ceramic capacitors
- polyester capacitors
- LEDs
That's what comes to mind.
I assume switches, connectors, IC sockets and such are fine as long as they're physically OK.
