Cornell Dubilier Aluminum Electrolytic 301R392U6R3HE2

The 301R392U6R3HE2 is a switching power grade radial aluminum electrolytic capacitor designed for high ripple current applications such as power supply outputs and UPS battery stiffening. It has a 2-lead configuration, a case size of 0.895 inches in diameter by 1.15 inches in length, a rated voltage of 6.3 Vdc, and a capacitance of 3900 µF. It features an ultra-low ESR of 86.8 mΩ at 25°C and a ripple current rating of 2.41 A at 85°C and 120 Hz. The capacitor operates over a temperature range of -55°C to +105°C and has a 4000-hour load life at full load and 85°C. Series inductance is 12 to 16 nH, enabling replacement of multiple smaller capacitors. The case is insulated with polyester and epoxied end seal. Lead spacing is 7.62 mm for both leads, with a lead diameter of 0.040 inches (18 AWG).
