Key Features

• Capacitance & Voltage — 10,000 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• High Ripple Current — Low-frequency ripple current of 33.2 A (120 Hz) and high-frequency ripple capability of 46.48 A (100 kHz), supporting demanding AC ripple and regenerative loads.
• Long Endurance — Load life specified at 5,000 hours with rated ripple current applied at 85°C; meets endurance requirements after restoration to 20°C.
• Leakage and Loss Characteristics — Specified leakage current 5,000 µA and tangent of loss angle (tan δ) 0.2 measured at 20°C, 120 Hz.
• Screw Terminal Mounting — Radial can with screw terminals for robust mechanical and electrical connections in heavy-current installations.
• Wide Operating Temperature — Specified operating range from –40°C to +85°C to cover industrial ambient conditions.
• Compact Can Package — φ90 × 120L can size (L: 12 × D: 9 cm) for a smaller footprint while delivering high ripple capability compared with previous LNC family members.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters and Motor Drives — Bulk energy storage and smoothing in inverter stages and servo drive regenerative circuits where high ripple current and endurance are required.
• High-Frequency Regenerative Circuits — Capacitor for buffering regenerative voltages in AC servomotors and equipment that require rapid charge–discharge cycles.
• Power Supply Filtering — Bulk filtering and decoupling in industrial power supplies subject to high ripple and long duty cycles.
• Pulse and Charge–Discharge Systems — Suited to applications that demand sustained charge–discharge performance, as evidenced by series endurance and charge–discharge specifications.

Unique Advantages

• High Ripple Handling: Specified for 33.2 A at 120 Hz and 46.48 A at 100 kHz, enabling use in heavy-ripple and high-frequency power environments.
• Proven Endurance: 5,000-hour rated life at 85°C under rated ripple current, providing predictable long-term performance in continuous-duty applications.
