Components are the most basic elements in an electronic circuit. Characteristic is that they're in a single package. There are passive and active components, from as simple as a zero-ohm resistor to as complex as a multi-billion transistor IC.

Which electronics components should I always have on hand?
Don't forget those 10A fast-blow fuses for your DVM

Discrete diode definition
'discrete' just means 'in a package by itself' - as opposed to 'integrated' into a package with other components. …

Is it current (and power dissipation) which damages things, not voltage?
Reverse biased PN junctions can only take so much voltage before they start to conduct. Sometimes they are designed for this, like zener diodes, but more often they're not. When multiple transistors a …

get a DC motor from household device?
Job-lots and dollar stores often have battery powered 'personal fans' or cheap toys, stuff like that, which are almost always built around low voltage DC brush motors - though 1.5V or 3V will be encou …

What's the best way to store and categorise resistors/capacitors/ICs/etc?
If really pressed for space, I think I'd lump everything 100 ohms and under in one bin, everything 1M and above in another, then one bin each for 100-1K, 1K-10K, 10k-100k and 100k-1M, but those things …

Keeping those IR LEDs
After LEDs fail, they rarely electrically resemble diodes any more. If you have a DVM that has a diode test mode, use that. Mine shows a representative forward drop of 1.2 to 1.5V for various sorts vi …
