I need to build a filter bank for 8 kv @ 3 AMPS, WHAT are the considerations for series and and parralel operation of two electrolytic banks to obtain 40 to 50 uf at 10kv? Oil capacitors are hard or
105º deg C rated electrolytic capacitors last much longer than 85º C rated electrolytics. - - I would use 2x 24 Panasonic [Matsushita] 470uF, 450v, 105º C rated units in series parall

Identical rated caps made in the USA by CDE are available from Mouser. Part # 381LX471M450A052 ( Mouser # 5985-450V470) are $11.29 ea Qty 10-99. These and the Panasonic are good caps but be careful o
The rating is 85ºC. The Panasonic capacitor is rated at 105ºC. The price on the CDE cap. is currently $10.21 at 10 - 99 units. . The Panasonic caps. are rated for ripple current in the Dig
Hi Carl and Igor, Why such a mess? This insistance on using electrolytic caps in such quantities puzzles me? HENRY uses a single 16UF @ 8KV oil filled and is available for $125 (new). This is less th
This is not the stated rating needed. The 105º C electrolytics are 35mm dia. by 50mm in length, and light in weight. Some have much lower ripple current ratings than high quality electrolytics.
If someone wants to use 24 capacitors and all the needed resistors and labor and expense (24 X $10-$14 each)as a better option to an oil filled or two, then go for it. Just because they all CAN be st
He said he needs 40uF @10kV. I provided a solution. compared to a 40uF oil filled 10kWV capacitor, less total volume and much lighter. 20 diodes per leg would be needed for an approx. 14kV supply. W
SNIP . Wrong again Rich. The 381LX series is rated at 105C. I do wish you could get a few simple facts straight. You read info and pricing on the 380LX series. The CDE are rated at the same as Panaso
