KMM
The KMM series is a high voltage, long life snap-in capacitor series that offers downsized versions
of the KMH series. The KMM capacitors have smaller case sizes and an extended rated lifetime
compared to the KMH capacitors. These characteristics plus high ripple current capability make
the KMM capacitors ideal for use in power supply filter circuits. The KMM capacitors are available
in 2 or 4-pin snap-in styles and 4 -pin straight terminals. The KMM series capacitors are RoHS
compliant offering Pb-free construction.
The standard KMM series capacitors are
not
solvent proof. Refer to guidelines and precautions on
the website for usage and installation conditions recommended for United Chemi-Con products.
