Key Features

• Capacitance & Voltage — 5.6 mF nominal capacitance with a 450 V DC rated voltage and ±20% tolerance (at 120 Hz, 20°C).
• High‑Temperature Operation — Rated for operation from −40°C to +105°C with a load life of 5000 hours at 105°C under ripple current.
• High Ripple Current Capability — Supports 19.6 A at 120 Hz and 27.44 A at 10 kHz, enabling effective filtering and energy buffering in high‑power circuits.
• High‑Frequency Charge/Discharge — Designed to cope with high‑speed charge/discharge loading and high‑frequency regenerative voltages used in AC servomotor and inverter systems.
• Mechanical & Mounting — Stud bolt (screw terminal) mount with radial can package for secure installation in industrial assemblies.
• Reliability & Endurance — Endurance requirements: after D.C. bias plus rated ripple current for 5000 hours at 105°C, capacitance, tan δ and leakage remain within specified limits; also validated for 50 million charge–discharge cycles per series datasheet.
• Leakage & Insulation — Leakage current meets the specified limit of not more than 3√CV (μA) or 5 mA after 5 minutes at 20°C; insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket (series specification).
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters and Motor Drives — Energy buffering and high‑frequency regenerative voltage handling for AC servomotors and general inverter circuits.
• Industrial Power Supplies — Bulk energy storage and smoothing in high‑voltage power supplies used in industrial equipment.
• Regenerative and Energy‑Recovery Circuits — Supports rapid charge/discharge cycles and high ripple currents required by regenerative braking and power recovery systems.
• High‑Frequency Power Electronics — Suitable for applications where high ripple at kHz frequencies is present, benefiting from the specified ripple current at 10 kHz.
