KRF
The KRF series capacitors are large diameter radial wire lead products with large capacitance that are
designed with a maximum impedance at high frequencies. These capacitors are also designed for
use over a wide temperature range of 40 C or 25 C to 105 C. Typical applications for the KRF
series include compact and lightweight equipment along with both the input and output filtering
circuits of switching power supplies.
The KRF series capacitors were developed to withstand HCFC cleaning agents for three minutes
by ultrasonic, vapor or immersion. This solvent proof design allows all circuit board components
to be cleaned together, at the same time, without resorting to more expensive epoxy end-sealed
capacitors. Refer to the Mini-Glossary for recommended cleaning conditions.
