SMM SERIES Engineering Bulletin Mar 07 SMM Series The SMM series is a high voltage, long life snap-in capacitor series that offers downsized versions of the SMH series. Compared to our SMH series, the SMM capacitors have a longer rated lifetime of 3,000 hours with the full rated ripple current applied and are also one case size smaller than equivalently rated SMH capacitors. These characteristics allow downsizing for many power supplies and will provide better reliability due to increased life. The SMM capacitors are available in 2 or 4-pin snap-in styles and 4-pin straight terminals. The SMM series capacitors are RoHS compliant offering Pb-free construction. The standard SMM 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 or 4-pin snap-in; optional 4-pin straight terminals. Capacitance range: 47 to 3,300µF. Voltage range: 160 to 450VDC. Category temperature range: 25C to 85C.
