SMQ
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 85 C
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.
