The SMH series capacitors are the standard 85 C, large capacitance, snap-in capacitors from
United Chemi-Con. The load life for the SMH series is 2,000 hours at 85 C with the rated ripple
current applied. The very high CV values and ripple current capabilities make these capacitors ideal
for use in power supply filter circuits. The SMH capacitors are available in 2 or 4-pin snap-in styles
and 4 or 5-pin straight terminals. The SMH series is RoHS compliant offering Pb-free construction.
The standard SMH 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.
