Capacitors for high voltage power supplies and voltage multipliers

Multiplier, filter, bypass and divider capacitors for lab, electrophoresis, electrospinning and photomultiplier supplies.

Almost any DC supply above a few kilovolts uses high voltage disc capacitors: in multiplier stages, output filters, bypassing and high voltage dividers. The Longxin range covers 4–30 kV and 100 pF–10 nF, so you can pick by working voltage and capacitance; look at the F series (4.7–10 nF) for larger filter capacitance and at the YL and E series where space is tight.
