Re: [TCML] RE: 942C current?

["Peter Terren" <pterren@xxxxxxxxxxxx>]

RS Electronics has 812 in stock of the 942C20P15K
http://octopart.com/942c20p15k-f-cornell+dubilier-4030345

Use Bart Anderson's MMC calculator to plan your MMC and currents etc.

I have just bought 120 of the 0.68uF cap in the 942 series for 2 x 0.1uF 
caps.  The peak and RMS currents seem to fit OK and the 0.33uF versions have 
lasted for perhaps 4 years with one failure out of 60 caps.
