Re: [TCML] maxwell Capacitor



Hi Jay,

This capacitor is a double-ended polypropylene film-foil pulse cap that can be safely used in a TC tank circuit.

Although MOST Maxwell 31xxx-series caps are rated at 1 pulse per second (PPS), this particular 0.09 uF 40 kV pulse capacitor is an exception. As long as you keep the RMS current below 25A, you should be able to run this cap at virtually any break rate.

Please note that a single capacitor should be limited to a maximum AC charging source of about 40/3 kV RMS (or about 13.3 kV RMS) to prevent overvolting during ringing in the tank circuit. The cap is rated for 20% voltage reversal, so the above voltage derating will keep it in a safe operating region. Since this cap uses older film-foil technology, it is not self-healing - be careful not to accidentally overvolt it.

The spec sheet for this cap can be found here:

Hello All,
Does any one have information on the Maxwell 31662?
Specifically how it might fair in coil use?
I cant locate a data sheet, just the spars information on the maxwell site.



Thanks,
John "Jay" Howson IV
