Type 401C –55 °C to 105 °C Low-ESR, Wide Temperature Grade
The Ultimate in Cold Performance and ESR
The Type 401C is the wide-temperature, low-voltage
version of the Type 450C. It is ideal for high-ripple
current military and industrial applications that need
full performance at cold temperatures. It also excels as a
power-supplyoutputcapacitorbecauseofitsexceptionally
low ESR. The extended cathode foil of the 401C assures
cool operation and heat flow from the capacitor element
to the can in all mounting orientations.
Highlights
• Better value than large snap-in capacitors
• Ripple Currents to >50 amps at 55 °C
• ESRs to 3.5 mΩ
• > 90% capacitance at –40 °C
• Thermal-Pak™ extended cathode construction
