• Voltage Rating — 220 V rated voltage for higher-voltage DC applications.
• High Temperature Endurance — Rated for 3000 hours at 105°C when subjected to DC bias plus rated ripple current, ensuring sustained performance in elevated-temperature environments.
• Ripple Current Capability — Low-frequency ripple current of 2.1 A at 120 Hz and high-frequency ripple current of 3.15 A at 50 kHz to support demanding ripple-load conditions.
• Low Leakage — Specified leakage current of 1270 µA, supporting stable bias behavior after application of rated voltage.
• Package & Mounting — Radial, snap-in can with dimensions φ35 × 30 mm (L), designed for secure snap-in mounting on printed circuit boards.
• Wide Operating Temperature — −40°C to +105°C category temperature range for versatility across ambient conditions.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• General-purpose power filtering — Bulk energy storage and smoothing in power conversion circuits that require 820 µF at 220 V.
