Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) rated at 450 V for DC-link and high-voltage power applications.
• High Ripple Current — Rated ripple current: 12.3 A at 120 Hz and 17.22 A at 100 kHz, supporting heavy AC ripple and high-frequency operation.
• Operating Temperature & Lifetime — Specified for –40°C to +85°C with a load life of 5000 hours at 85°C under rated ripple conditions.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-impedance high-current connections.
• Endurance & Charge–Discharge Performance — Endurance validated by charge–discharge testing: 50 million cycles at ΔV = rated × 0.3, 3 Hz, demonstrating suitability for rapid cycling loads.
• Size & Packaging — Physical dimensions: L: 8.5 × D: 6.35 cm; Height (seated max): 3.346 inch; radial can with screw terminals.
• Tolerance & Leakage — Capacitance tolerance ±20%; leakage current after 5 minutes ≤ 3√(V) µA or 5 mA (whichever is smaller) at 20°C.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies / Inverters — Used in DC-link and smoothing roles for inverter circuitry in industrial power supplies.
• AC Servomotor Drives — Handles high-frequency regenerative voltages encountered in servo drive systems.
• High-speed Charge–Discharge Systems — Suited for circuits that require rapid charge–discharge capability and sustained ripple loading.
