• Electrical Performance — 1.8 mF capacitance with ±20% tolerance, rated at 500 V DC (part of a series rated up to DC525 V).
• High Ripple Current Capability — Specified ripple current of 7.4 A at 120 Hz and 10.36 A at 10 kHz to support high‑frequency inverter and regenerative loads.
• Thermal and Lifetime Characteristics — Operating temperature range −40°C to +105°C with a load life of 5000 hours at 105°C under rated ripple current.
• Charge/Discharge Endurance — Endurance for charge/discharge behavior specified after 50 million cycles (ΔV = rated voltage ±0.3, 3 Hz), meeting capacitance, tan δ and leakage current criteria.
• Leakage and Insulation — Leakage current after 5 minutes at 20°C limited to 3√(C·V) µA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Voltage Withstand — Voltage proof rating: no abnormality at AC 2500 V applied for 1 minute between terminal and bracket.
• Package and Mounting — Screw‑terminal, radial can with separate bracket supply; nominal dimensions L: 10.0 cm × D: 6.35 cm and seated height max 3.937 inch.
• RoHS Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — Provides bulk energy storage and smoothing for inverter DC link circuits in industrial drives and power modules.
• AC Servomotor Regeneration — Suited for high‑frequency regenerative voltage handling in AC servomotor systems and regenerative braking circuits.
• High‑Frequency Charge/Discharge Systems — Handles high‑speed charge/discharge cycles for power conversion and energy buffering in inverter and regenerative applications.
