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.
