• High ripple‑current handling: Rated ripple current of 30 A at 120 Hz and 42 A at 100 kHz, enabling use in high‑ripple DC link and regenerative circuits.
• Endurance / Load life: Load life specified as 5000 hours at 85 °C with rated DC bias plus rated ripple current applied; post‑test limits include capacitance change within ±20% and leakage and tan δ within specified limits.
• Temperature range & stability: Operational range −40 °C to +85 °C with an impedance ratio Z(−40 °C)/Z(+20 °C) up to 8 per series specifications.
• Screw‑terminal radial can package: Robust screw terminals and radial can format for secure, low‑impedance connections in industrial assemblies; size dimensions L: 14.5 × D: 9 cm.
• Low leakage & insulation: Leakage current after 5 minutes is specified as not more than 3√(V) µA or 5 mA (whichever is smaller) at 20 °C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Dielectric & safety testing: Voltage proof verified at AC 2500 V for 1 minute between terminal and bracket; endurance in charge‑discharge behavior tested to 50 million cycles (ΔV = 0.3 × rated voltage, 3 Hz).
• RoHS compliance: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies: DC link and smoothing capacitor in inverter circuitry for industrial drives and power conversion systems.
• AC servomotor regenerative circuits: Handles high‑frequency regenerative voltages in servo drives and regenerative braking systems.
• High‑frequency charge/discharge circuits: Suitable where rapid charge and discharge cycles and high ripple currents are present.
• General inverter systems: Energy storage and ripple suppression in general-purpose inverter topologies used in industrial equipment.

Unique Advantages
