KMQ
The KMQ series is a snap-in capacitor series that offers downsized versions of the current
miniaturized KMM series. These capacitors have a rated lifetime of 2,000 hours at 105 C with the
rated ripple current applied. With high ripple current capability and higher CV per case size than the
KMM series, the KMQ capacitors are suitable for many downsized power supply circuits. The
standard KMQ capacitors have a 2-pin snap-in terminal style. The KMQ series is RoHS compliant
offering Pb -free construction and PET (polyester) sleeves with no end disk as the standard.
The standard KMQ 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.
