500 h at 95 °C. Capacitance, ESR and DCL meet initial
requirements.
10 to 55 Hz, 0.06” and 10 g max, 2 h each plane.
The Type 400C is the PC-mount equivalent for Type
500C screw-terminal computergrade capacitor. It’s for
bus filtering applications where long life is critical like
telecom systems and industrial power supplies. Type
400C delivers 2 to 3 times the life of Type 4CMC,
and above 250 V it has nearly the same capacitance.
Its extended cathode foil assures cool operation with
heatflow from the capacitor element to the can in all
mounting orientations.
Highlights
• More than 10 years life in most applications
• Ripple Currents to > 50 amps at 55 °C
• 3-leads
• Printed-circuit mounting
• Thermal-Pak™ extended cathode construction
