Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-impedance connections in power assemblies.
• High Ripple Current — 9.3 A low-frequency ripple current (120 Hz) and 13.02 A high-frequency ripple current (100 kHz), enabling support for heavy AC ripple in inverter/regenerative circuits.
• Low Dissipation Factor — tan δ = 0.2 measured at 20°C and 120 Hz for predictable ESR-related behavior in filtering and decoupling roles.
• Leakage Current — Specified leakage current of 2,070 µA (typical datum provided for the part), allowing designers to budget standby losses.
• Endurance — 5,000 hours rated life at 85°C under DC bias plus rated ripple current; meets endurance requirements for extended operation in thermal stress conditions.
• Operating Temperature — Rated for −40°C to +85°C to accommodate a broad range of industrial ambient conditions.
• Electrical Safety Tests — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket and voltage proof to AC 2,500 V for 1 minute, per series test criteria.
• Durability in Charge–Discharge Cycling — Meets charge–discharge endurance test conditions up to 50 million cycles (ΔV = rated × 0.3, 3 Hz) as specified for the series.
• RoHS Compliant — Conforms to RoHS directive requirements for restricted substances.

Typical Applications

• Industrial Inverters — Bulk energy storage and ripple smoothing in inverter front-ends where 400 V DC rails and high ripple handling are required.
• AC Servomotor Regeneration — Support for high-frequency regenerative voltage and rapid charge–discharge cycles in motor drive DC-link circuits.
• Power Supplies for Industrial Equipment — Filtering and energy buffering in high-voltage power supplies used in factory automation and motion control.
• General Power Electronics — Decoupling and bulk capacitance in systems requiring long endurance at elevated temperature and secure screw-terminal connections.

Unique Advantages

• High ripple capability: Specified 9.3 A (120 Hz) and 13.02 A (100 kHz) ripple currents enable reliable performance under heavy AC ripple loads common to inverter and regenerative systems.
• Compact high-voltage package: φ51 × 65 mm screw-terminal can delivers 1.2 mF at 400 V in a space-efficient form factor for power assemblies.
• Long thermal endurance: 5,000 hours at 85°C under rated conditions provides predictable lifetime behavior for industrial deployments.
• Designed for frequent charge–discharge: Meets series-level charge–discharge endurance testing (50 million cycles at ΔV = rated × 0.3), supporting fast switching and regenerative applications.
• Robust electrical isolation tests: High insulation resistance and AC voltage proof between terminal and bracket simplify integration into high-voltage DC-link designs.
• Secure screw terminals: Facilitates low-impedance, vibration-resistant connections in rack-mounted and cabineted power equipment.
