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.
