Re: [TCML] maxwell Capacitor

[jhowson4@xxxxxxxxxxx]

Thank you, 


I could not find a way on the site to get to the pdf datasheets, but your link has shown me how to get to them all. =) 
Cheers for that! 

The 25A hard limit is killing me, as I need around 100A .04uf. Oh well, these caps are not a good investment as such. 



Thanks, 
John "Jay" Howson IV

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:
