Re: LF: Capacitor warning and First 500kHz Class E breadboard (score: 1): Author: "Alan Melia" <[email protected]>; Date: Wed, 12 Jan 2011 01:17:44 +0100; Hi Piotr, you should note that these old mics caps were not usually rated for high RF currents. At that capacitance they consist of a stack of micas with foil or maybe evaporated plating. Either way; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-01/msg00703.html (14,608 bytes)
