I have a bunch of parts that I have scavenged over the years, but I don't know what they are called, so I can't look them up online. Could the kind people here give me a clue.
1 ? Possibly a Low Value Capacitor.
2 & 3 are Signal Diodes.
4 Down, looks like a 20pF cap.
5 down, looks like a 1 amp diode
6 Unknown
7 Down, 10 pF, 1 kV Rated.
#4, Yes Possibly a Thermistor.
Test it with an Ohm Meter.
A Cap will show Infinity Resistance.
A Thermister Will show an actual Resistance and will change resistance with temperature.
#1 Also check it for resistance.
An Inductor will have a somewhat Low resistance.
A Diode will measure Low in one Direction, High in the other Direction.
