Temperature
The KMM series capacitors are new downsized high temperature snap-in capacitors from United
Chemi-Con. The smaller sizes and longer rated lifetime compared to the KMH series make these
capacitors ideal for use in power supply filter circuits. The KMM series also has a very high ripple
current capability making them ideal for use in filter circuits. The KMM capacitors are available in 2 or
4-pin snap-in styles and 3 or 4 -pin straight terminals with or without standoffs.
The standard KMM capacitors are non-solvent proof and are not recommended when halogenated
cleaning solvents are used. Refer to the Mini-Glossary for recommended cleaning conditions.
