Introducing the high-performance CAP ALUM 330UF 20% 420V FLTPCK from KNOWLES / CORNELL DUBILIER, designed for demanding electronic applications requiring reliability and long life. Manufactured in the USA, this fixed aluminum electrolytic capacitor combines low profile design with exceptional endurance suitable for military, telecom, and computer circuit modules.
Product Features
Very low profile flatpack design, ideal for voltage holdup and filtering in compact assemblies
High energy storage capacity with up to 20 joules in a 1/2” height
Nearly hermetic welded seal ensures a 50-year lifespan at +45°C
Can withstand altitudes exceeding 80,000 feet
Enhanced ripple current capability when heatsink is applied, doubling the capacity
Temperature range from –55°C to +85°C with rated voltages up to 450Vdc
Capacitance tolerance of ±20%, with leakage current ≤ 0.002 CV µA at 25°C
