Cornell Dubilier Aluminum Electrolytic NR301R561M025EK2

The NR301R561M025EK2 is a radial leaded aluminum electrolytic capacitor from the 301R series, designed for switching power supply outputs and UPS battery stiffening. It features an ultra-low ESR of 193 mΩ at 25°C, a ripple current rating of 1.79 A at 85°C, and operates within a temperature range of -55°C to +105°C with a rated voltage of 25 Vdc. The capacitor has a capacitance of 560 µF with a tolerance of ±10% and is supplied in a 0.51 × 1.04 inch insulated case with polyester insulation and epoxy end seal. It supports a 4000-hour load life at full load and 85°C, and exhibits greater than 90% capacitance retention at -40°C. The device replaces multiple smaller capacitors, reducing component count in high-ripple-current applications.
