The 101C402T200CB2B is a Type 101C low-ESR, wide-temperature grade aluminum electrolytic capacitor rated for 200 VDC (275 VDC surge) with a capacitance of 4,000 µF. This capacitor is designed to operate reliably across an extended temperature range from -55°C to +105°C, making it ideal for demanding military and industrial applications. It features an exceptionally low equivalent series resistance (ESR) of 49.7 mO at 25°C and a maximum ripple current rating of 11.2 A at 85°C, with a nominal size of 2.5 inches diameter by 3.125 inches length. The extended cathode foil construction ensures efficient heat dissipation in all mounting orientations, and the capacitor is rated for 5,000 hours of load life. Common applications include high-ripple current power supplies, military equipment, and industrial systems requiring full performance across extreme temperature ranges.
