I need help identifying several components that I salvaged from various devices. What sucks is I don't know what this stuff even is to look up how to use them/what they're for. If someone could help put a name to some of these components and/or give a general idea of what they're used for it would be greatly appreciated.
p.s. I'm highly interested to learn about # 3, 6, & 7
3 - looks like an inductor.
6 - a Diode
7 - not sure, either a crystal or an inductive lamp or bulb or maybe fuse?
1 a. is capacitor probably in the 200v - 300v
1.b a ceramic cap or maybe MOV (hard to tell with this picture, hard to read writing)
1.c a mov or ceramic cap,.
4 a. cap,b.relay,c. relay?
5 a 2watt 2ohm resistor
Probably got a couple wrong, 7 and 1
I agree with most of what cjdelphi said, with a few exceptions.
1a is probably a 250V mylar capacitor.
1b may be a MOV (overvoltage protection device commonly used in surge protectors) or a ceramic capacitor.
1c looks like a ceramic capacitor. It looks to thin to be a MOV. Is it labeled something like 0.1u or 0.01u or 0.047u or 47n?
2 and 3 do indeed look like inductors, ferrite core. If you cut away the heatshrink, you should see a dumbell made of a black brittle substance with enameled wire wrapped around it.
4a is a capacitor. That style is often used as AC line bypass.
4b and c do indeed look like relays. 4b, 24V is the relay coil voltage. The current and voltage ratings are the contact maximum ratings.
5 is a 2W 2.7 ohm resistor. It is common to put an R in place of a decimal point, because it is easy to miss a little black spot on a part like that.
Hard to tell because of the angle, but I think 6 is just a ferrite bead with a wire through it. If that orange stuff is just glue holding the wire in. If the wire is a part of the black shape and there is a white ring around one end, it is probably a diode.
7 might be more capacitors. Or if that is a metal cylinder with the leads bent around in a U with heat shrink over it and a black band on one end, they might be diodes.
Can you get a clear picture, right from overhead?
Thanks for the responses. Maybe now I can start figuring out what to do with some of this. Here's a straight down view of this stuff (a few extras in this picture) and I didn't re-size it down too much so you can see extra detail.
I still couldn't get the writing on the boxes/relays (flash-glare, no flash-too dark), so I'll just tell you here what they say. And by the way, I believe I might have looked up the "OEG" things by the 'PCD...' numbers and saw that they were relays, but I'm still unsure about the small light blue thing.
Black:
OEG
PCD-124D1M 24V
10A 277V
15A 125VAC Res.
10A 250VAC Res.
Blue:
***Almost identical info; either way blue and black are the same thing just with different amps and volts
Small Light Blue:
***Mainly jibberish on the side (lol), but the top says "100nM275V~X2
PCX2 335M MKP"
The matte black cylinder with red stuff on it is a ferrite bead with a wire through it. Basically a low inductance, high loss device meant to block and absorb unwanted higher frequency noise.
The 3 lead blue thing looks like a 4.19MHz (MC = megacycles?) ceramic resonator.
The grey cylinder is a 20uH inductor.
The light blue thing is 100nF aka 0.1uF, 275V. X2 means it is rated for up to 2500V impulse. They are used for interference suppression.
The two silver inside clear are polystyrene capacitors. 102 means 10 x 10^2 pF so 1000pF or 1nF, and 472 means 47 x 10^2 so 4700pf or 4.7nF. They have excellent characteristics, very stable with respect to time and temperature, and very low loss. Used in RF and in low noise audio filters.
Does the big red lump say 155K and 250M? That would likely be a mylar film capacitor 15 x 10^5 pF therefore 1.5uF at 250V. The K is the tolerance and means +-10%.
Little blue disc:
B
471K
1KV
Means 47 x 10^1 or 470pF, 1kV rating, K is +-10% tolerance. Looks like a ceramic capacitor.
The fat blue disc does indeed seem to be a MOV or Varistor.
The little blue thing labeled 334U or 334J is probably a J smeared to look like a U. 334J would be 330000pF, aka 330nF, aka 0.33uF with 5% tolerance. Not sure if that is mylar or ceramic.
The blue disc:
SINCERA
7D271K
Looks like a ceramic capacitor. 270pF, 5% tolerance. The voltage rating may be on the other side.
The relays I've already touched on. Ratings at a given voltage are shown. The DC ratings would be much lower since the arc from DC is harder to break, just so you know.
just like the commercial
salvages parts $1.87
internet connection $87/month
engineering review - priceless !
for most of the parts, there are printed numbers and letters
put them in google, see what comes back.
the more often you do that, the better you get at it.
the problem is using what you have.
if you want to get a lot of parts, get a circuit board from an alarm company. they toss the old stuff out.
use a hot air gun or blow torch
put a layer of aluminum foil out
and a brick
heat the board until some of the solder melts.
with the LEAD SIDE DOWN, wack the board on the brick.
the wet solder flies off onto the aluminum and the other parts fly all over the place, free of most of the solder.
WEAR EYE PROTECTION AND GLOVES !!!!!!
HOT LEAD FLYING AROUND !!!!!!!!
