LARGE SIZED ALUMINUM ELECTROLYTIC CAPACITORS KM Series

Product Overview
The KM Series large-sized aluminum electrolytic capacitors are designed for general-purpose applications requiring high reliability and performance. Featuring a snap-in terminal type, these capacitors offer high ripple current capability and long endurance at elevated temperatures (105 for 2000 hours). They are equipped with a safety vent designed on the aluminum case and are RoHS2.0 compliant. Ideal for professional power supplies, frequency converters, inverters, UPS systems, medical power supplies, air conditioners, and professional arena power amplifiers.

Product Attributes

Brand: KM Series
Type: Large Sized Aluminum Electrolytic Capacitors
Terminal Type: Snap-in

Important Note: The endurance of aluminum electrolytic capacitors is reduced by self-heating from ripple current. Lifetime is halved for every 5 rise in internal temperature. To ensure long life, reduce the RMS ripple current in actual use.
