KMQ SERIES Engineering Bulletin Mar 07 KMQ Series 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 105C 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. Summary of Specifications PC board 2-pin snap-in terminals. Capacitance range: 68 to 33,000µF. Voltage range: 35, 50, 160 to 450VDC. Category temperature range: 40C to 105C for 35V and 50V;25C to 105C for 160 to 450V. Leakage current: 3 CV (µA) maximum after 5 minutes at 20C.
