New for September 2008!
This page will show you why you need to worry about the equivalent
series resistance of charge storage capacitors in pulsed applications.
The equivalent series rsistance
of a capacitor can be a strong function of voltage n ceramic capacitors,
but a near constant in electrolytics.
In the case of electrolytic capacitors
powering a pulsed transmitter, the ESR of a 4.7 uF capacitor might
be on the order of one ohm.
