The SMM series capacitors are new longer life snap-in capacitors with smaller case sizes. When
compared to our SMH snap-in series, the SMM capacitors not only have an extended rated lifetime
from 2,000 to 3,000 hours with the full rated ripple current applied, but also are one case size smaller
than equivalently rated SMH capacitors. These characteristics allow downsizing for many power
supplies and also provide better reliability due to the increased life.
The standard SMM capacitors are non-solvent proof and are not recommended when halogenated
cleaning solvents are used. Refer to the Mini-Glossary for recommended cleaning conditions.
