• Endurance and charge‑discharge durability — Meets endurance after 20 million charge/discharge cycles (ΔV = rated × 0.3, 3 Hz) at room temperature per datasheet limits.
• Leakage current — After 5 minutes at rated voltage, leakage current is specified as not more than 3√V (µA) or 5 mA, whichever is smaller (measured at 20 °C).
• Package and mounting — Radial can with screw terminals for secure high‑current connections and easy installation in power racks and bus assemblies; body dimensions L: 19 × D: 6.35 cm.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC servo motor regenerative circuits — Handles high‑frequency regenerative voltages and rapid charge/discharge cycles in servo drive energy recovery systems.
• General inverter power stages — Provides bulk energy storage and ripple handling for inverter DC bus filtering under fluctuating loads.
• Voltage‑doubler rectifier circuits — Suited for rectifier circuits including voltage doubler topologies that require high voltage and capacitance.
• Equipment in fluctuating voltage environments — Designed to maintain performance where supply voltage varies, delivering stability and endurance.

Unique Advantages

• High stored energy at elevated voltage: 8.2 mF at 350 V provides substantial bulk capacitance for DC bus and energy buffering applications.
• Robust ripple handling: Specified ripple currents at both low and high frequency (27.1 A at 120 Hz, 37.94 A at 10 kHz) reduce thermal stress and support demanding power waveforms.
• Designed for rapid charge/discharge: The series is explicitly tailored for high‑speed charge/discharge behavior, supporting regenerative and braking cycles.
• Long endurance at high temperature: 5000 hours at 85 °C under rated conditions offers predictable life for industrial power systems.
• Screw‑terminal radial package: Screw terminals simplify installation for high‑current connections and mechanical retention in power assemblies.
• Measured leakage and stability: Clear leakage current limits and low‑temperature impedance characteristics (Z(−25 °C) / Z(+20 °C) = 8) allow reliable design margins.
