Vishay 15000uf 100V Cap - Good ESR?

PreCD · 19th December 2011, 03:57 PM

I am looking to replace the filter caps in my power amp. These look like good filter caps and match the current values of what I have int there now. Opinions?

CAP 100V 15000UF ELECT SCREW - MAL210119153E3

These are good capacitors (formerly Philips), though slightly better brands may be available.

If you want to know some alternatives, then equally important: what is their size (diameter x height, in mm), as you would probably like to fit the new ones in the current position, using existing brackets. And: is a PCB directly screwed on top of it? In which case the terminal spacing must be identical with the new caps. In that capacity and voltage rating, there is a large diversity in sizes, and in terminal spacing.

Interesting alternatives might be Rifa and Mallory.

Yes these fit my brackets and I have no boards strapping to the screw terminals. I do have bleeder resistors on top in 3.9 ohm values. I was thinking of using Mills resistors for those but they are a little pricey for that application maybe?

The spec sheet on the Vishay capacitors is below:

Max. ESR = 16 Mohms @100Hz

Done and done. Ordered the Vishays from Digikey along with 3.9kOhm 3W Metal Film resistors which reside on the filter caps at this time. Might as well replace those too.
