Key Features

• Capacitance & Voltage — 1.2 mF nominal capacitance with a rated voltage of 400 V and capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High Ripple-Current Capability — Low-frequency ripple current 9.3 A at 120 Hz and high-frequency ripple current 13.02 A at 100 kHz, suitable for demanding DC-link and high-frequency charge/discharge loads.
• Endurance & Life — Rated for 5000 hours of operation at 85°C under DC bias plus rated ripple current; capacitance, tan δ and leakage current meet the specified endurance limits after life test.
• Electrical Loss & Leakage — Dissipation factor (tan δ) specified as 0.2 (measured at 20°C, 120 Hz). Typical leakage current listed as 2070 µA.
• Temperature & Stability — Operating temperature range −40°C to +85°C; impedance ratio Z(−40°C)/Z(+20°C) is specified in the series data.
• Mounting & Package — Radial, can-style screw-terminal package (φ51 × 65 L) with screw terminals for secure, high-current connections in industrial assemblies.
• Safety & Insulation — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; voltage proof testing per series specification.
• Regulatory — RoHS compliant per series documentation.

Typical Applications

• Industrial Power Supplies — DC-link smoothing and energy buffering in inverter power supplies where high ripple current and long life are required.
• Inverter & Motor Drives — Support for high-frequency regenerative voltages in AC servomotor and general inverter systems, including repeated charge/discharge cycles.
• High-Speed Charge/Discharge Circuits — Applications that demand fast charge/discharge capability and high ripple tolerance for transient energy handling.

Unique Advantages

• High ripple tolerance: Specified 9.3 A at 120 Hz and 13.02 A at 100 kHz enables robust handling of low- and high-frequency ripple currents in power-electronics circuits.
• Long operational life: 5000 hours at 85°C under rated ripple and bias conditions provides predictable end-of-life behavior for industrial systems.
• Compact screw-terminal can: φ51 × 65 mm radial can with screw terminals simplifies mounting and provides secure connections for high-current DC-link applications.
• Wide temperature range: −40°C to +85°C operation suits a broad set of industrial environments.
• Measured electrical characteristics: Specified tan δ (0.2 at 20°C, 120 Hz) and measured leakage current (2070 µA) give clear, testable electrical performance metrics.
• RoHS compliant: Meets RoHS directive requirements as indicated in the series documentation.
