Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 400 V rated voltage suitable for high-voltage DC applications.
• High-temperature long life — Endurance specified for 10,000 hours at 105°C when DC bias plus rated ripple current is applied; capacitance change limit ±25% after test.
• Snap-in radial can package — Snap-in terminal mounting for secure mechanical retention and ease of assembly in power equipment.
• Operating temperature range — Specified for –25°C to +105°C for 400 V/450 V ratings, enabling use in elevated-temperature environments.
• Ripple current performance — Rated ripple current 1.00 A at 120 Hz and 1.43 A at 50 kHz (product-level values); series frequency coefficients for 400/450 V: 50 Hz 0.77, 60 Hz 0.82, 120 Hz 1.00, 300 Hz 1.16, 1 kHz 1.30, 10 kHz 1.41, 50 kHz+ 1.43.
• Leakage current specification — Initial leakage current limit given by I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C (C in µF, V in V).
• Electrical loss (tan δ) — Maximum specified tan δ for 200–400 V is 0.15, supporting predictable dissipation characteristics at 120 Hz and 20°C.
• Regulatory compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies — Bulk smoothing and ripple suppression in high-voltage DC rails where 400 V rating and 220 µF capacitance are required.
