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.

I am going to disagree with chemelec on a couple of these:

1 I am inclined to think that this is an inductor.

4 possibly a thermistor.

5 A diode BYV?? Turn it over and there should be a couple of numbers. Easy to look up, just google BYVxx

6 Possibly a ceramic resonator.

7 I think more a 1000pF (1K) capacitor.
But then it does look a bit chunky for a low voltage 1000pF cap.
Difficult to say.

I think 1 may be an old glass germanium diode.

#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.

Disagree...

No1 is a beetle with two legs only. Common, anyone can see that. Oh well, at least I can

This is quite a collection of odd components. The three-legged #6 thing could be a dual cap or a resonator.

The glass things look a lot like diodes, but I have seen very high value resistors packaged this way.

#5 is a diode and you can likely read the numbers off it an google it.
#7 is definitely a cap. A 10 pf 1kV cap

I've seen devices like #6 which have been suppression devices, a pair of diodes or tranzorbs with a ceramic bead inbetween.
