Quick question on the "BASIC ELECTRONICS COMPONENTS" tutorial
« on: December 13, 2007, 11:06:27 AM »
Quote from: capacitor section of tutorial
Get a capacitor that is rated at least twice the voltage you expect to go through it. Have it rated at 1mF-10mF for every amp required. For example, if your 20V motors will use 3 amps, use a 3mF-30mF 50V rated capacitor.

is it saying a millifarad? or is it supposed uF micro farad?

milli-farad

Those numbers are more rule of thumb. Basically you want maximum capacitance, but you don't want giant capacitors on your robot either. This is just a balance area that I like.

ah ok. If im not mistaken, 1mF = 1000uF?

I recently fixed a big 7.1 channel receiver for someone that had two 15,000uF caps in it O_O and a huge like 25lb(~11.34kg) transformer lol, it was pretty sweet.

yup

break open a power supply if you want some big caps ;D

car audio setups have huge caps for the subs

like 2" diamiter and 5" long

The ones for subs in cars though can be from .5F up to 2F depending on how much you want to spend.
a 2F cap can be upwards of almost $200 if I'm not too old now.
