Key Features

• Capacitance & Voltage — 220 µF capacitance at a 315 V rated voltage for higher-voltage circuits.
• High-temperature Endurance — Specified to endure 3000 hours under rated ripple current at 105°C, with capacitance stability within ±20% after the endurance test.
• Ripple Current Performance — Rated ripple current: 1.04 A at 120 Hz and 1.487 A at 50 kHz, supporting both low- and high-frequency ripple conditions.
• Operating Temperature Range — Rated for operation from −25°C to +105°C, suitable for elevated-temperature environments consistent with its endurance rating.
• Package & Mounting — Snap-in radial can (snap-in terminal) for secure PCB mounting and mechanical stability.
• Compact Footprint — 22 mm diameter × 25 mm length (L: 2.5 × D: 3.0 cm) for space-constrained designs.
• Polarized Electrolytic — Polarized construction appropriate for DC applications requiring electrolytic capacitors.
• RoHS Compliant — Complies with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Bulk and smoothing capacitance in higher-voltage DC power supplies, leveraging the 315 V rating and 220 µF capacitance.
• General-purpose power electronics — Suitable for general-purpose circuits that require stable capacitance and endurance at elevated temperatures.
• High-frequency ripple environments — Applications with significant ripple content where rated ripple current at 120 Hz and 50 kHz is required.

Unique Advantages

• High-voltage capability: 315 V rating enables use in higher-voltage DC circuits without resorting to series stacks.
