The KMH series capacitors are the standard 105 C , large capacitance, snap-in capacitors from
United Chemi-Con. The load life for the KMH series is 2,000 hours at 105 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 KMH capacitors are available in 2 or 4-pin snap-in styles
and 4 or 5-pin straight terminals. The KMH series is RoHS compliant offering Pb-free construction.
The standard KMH 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.
