SMQ SERIES Engineering Bulletin Mar 07 SMQ Series The SMQ series is a high voltage snap-in capacitor series that offers downsized versions of the current miniaturized SMM series. These capacitors have a rated lifetime of 2,000 hours at 85C with the rated ripple current applied. With high ripple current capability and higher CV per case size than the SMM series, the SMQ capacitors are suitable for many downsized power supply circuits. The standard SMQ capacitors have a 2-pin snap-in terminal style. The SMQ series is RoHS compliant offering Pb-free construction and PET (polyester ) sleeves with no end disk as the standard. The standard SMQ 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: 82 to 3,900µF. Voltage range: 160 to 450VDC. Category temperature range: 25C to 85C.
