Key Features

• Electrical Core — 3300 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C; polarized design rated for 450 V.
• High Ripple Current Capability — Rated ripple current of 15.6 A at 120 Hz and 21.84 A at 100 kHz, suited to continuous AC and high-frequency regenerative loading.
• Thermal and Lifetime Performance — Operates across −40°C to +85°C with a specified load life of 5000 hours at 85°C when rated ripple current is applied.
• Charge–Discharge Endurance — Qualified for charge–discharge endurance testing (50 million cycles at ΔV = rated × 0.3, 3 Hz) with defined limits on capacitance, tan δ, and leakage current.
• Leakage and Insulation — Leakage current after 5 minutes at 20°C is limited to 3√V µA or 5 mA, whichever is smaller; insulation resistance >100 MΩ at DC 500 V between terminal and bracket, and AC 2500 V voltage-proof test.
• Mechanical & Mounting — Screw terminal, radial can package for secure electrical and mechanical connection; compact footprint (L: 11.5 cm × D: 6.35 cm).
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — Bulk energy storage and smoothing for inverter front-ends, supporting continuous ripple current and extended lifetime under 85°C operation.
• AC Servomotor Regeneration — Handles high-frequency regenerative voltages and rapid charge–discharge cycles in motor drive systems.
