## Description

The KEMET ELG477M250AR3AA is a polar aluminum electrolytic capacitor belonging to the ELG series, engineered with a snap-in terminal mounting style for secure PCB retention. Featuring a nominal capacitance of 470 µF with a ±20% tolerance, this component is rated for a maximum DC working voltage of 250 VDC and a surge voltage capability up to 300 VDC. The physical construction utilizes a cylindrical can measuring 25 mm in diameter and 35 mm in height, equipped with a standard 2-pin configuration featuring a 10 mm lead spacing and 5.8 mm terminal length.

Designed for robust thermal and electrical performance, the capacitor operates across a temperature range of -25°C to +105°C, delivering an operational lifetime of 2,000 hours at its maximum rated temperature of 105°C. Key electrical parameters include a maximum equivalent series resistance (ESR) of 0.423 ohms at 120 Hz and 20°C, a dissipation factor of 15% under identical test conditions, and a maximum allowable ripple current of 1.5 A at 120 Hz and 105°C. It exhibits a DC leakage current of 2.3 mA measured after 5 minutes at 20°C, alongside an impedance ratio of 4 at -25°C.

This snap-in aluminum electrolytic capacitor is well-suited for high-voltage power conversion topologies, including bulk energy storage and DC-link filtering stages in switched-mode power supplies (SMPS), industrial motor drives, and renewable energy inverter systems. The robust 25x35 mm package dimensions and reliable snap-in terminals ensure stable mechanical and electrical integration on printed circuit boards requiring high capacitance-voltage products.
