boom3 Posted November 27, 2005 Share Posted November 27, 2005 Once upon a time, there was a company called Component Research Corporation (CRC) that made hermetically sealed (glass to metal) capacitors in teflon, polystyrene, polypropylene and other high-end dielectrics for the military, NASA, and other critical applications. They published a very interesting catalog that was an education in the performance and testing of non-Mylar films. It was available in the old EEM master parts catalogs (now replaced by the web, I suppose) Their usual line of caps was cylindrical, in a natural aluminum color, with the value and other information printed in black ink. If you find any of these, hang on to them, they're golden. Sadly, CRC went under last year and I am not sure of who has taken their place in the market. I don't remember all their dielectric codes but J11 was teflon. Their tolerences tended to be conservative. All the plus or minus 5 per cent CRCs I've ever measured (some with lab grade LCR bridges) were closer to 2 percent tolerance. At the time they were in production, their speaker crossover value caps were pretty expensive, much moreso than the GE motor caps. There are still retailers selling CRC caps, one is DF Sales, http://dfsales.com Quote Link to comment Share on other sites More sharing options...
