SMQ Series
The SMQ series capacitors are new downsized versions of the general purpose SMG series, but
offer an extended capacitance range from 0.1 to 47,000µF. The SMQ capacitors have a rated lifetime
of 2,000 hours at 85C and a category temperature range of 40Cto
85C except for the 450
volt products which have a range of 25Cto
85C. This series is available in 9 case diameters
from 5 to 22mm and range from 11 to 50mm in length.
The SMQ series capacitors are non-solvent proof. Refer to the Mini-Glossary for cleaning guidelines
and recommended cleaning agents that are compatible with United Chemi-Con products.
