Product Overview
The Cornell Dubilier Type 401C is a wide-temperature, low-voltage
capacitor designed for high-ripple current military and industrial
applications. It excels in cold environments, offering full
performance down to -55 C. Its exceptionally low ESR makes it ideal
for power-supply output applications. The extended cathode foil
construction ensures cool operation and efficient heat dissipation
regardless of mounting orientation. It provides a better value
compared to large snap-in capacitors, with ripple current
capabilities exceeding 50 amps at 55 C and ESRs as low as 3.5 m.
Capacitance retention is over 90% at -40 C.
