1. [Amps] KW Rated Low Pass Filter Caps? (score: 1): Author: doc <kd4e@verizon.net>; Date: Fri, 31 Dec 2004 10:54:14 -0500; I need to access the gathered wisdom here ... I am building a switched low pass filter for my full legal 160-10M solid state amp (1500W). I have access to a number of free (from a friend) older surpl; /archives//html/Amps/2004-12/msg00405.html (8,600 bytes)

(score: 1): Author: "wc6w@juno.com" <wc6w@juno.com>; Date: Fri, 31 Dec 2004 16:23:57 GMT; Hi Doc, Nope, but, I'd verify the original markings before using them. Yes. Plenty of headroom for a KW at 50 ohms. No. Ceramics are not the best in this application. I think I just answered that...; /archives//html/Amps/2004-12/msg00406.html (9,424 bytes)

Yours, and a private reply, both said the same thing and the last bit about the "small 1KV air variables may be paralleled with the micas. The ARCO 500V mica padders will also survive in this; /archives//html/Amps/2004-12/msg00407.html (9,829 bytes)

Are the Micas likely to have drifted significantly in value over time? Measure the values. 2. Is 2,500V a sufficient rating for this application?

They are used widely in BC applications in AM service because they are effective below 1.0MHz. Above 1 MHz., they tend to heat up too fast and drift; /archives//html/Amps/2004-12/msg00409.html (8,728 bytes)
