Designed for demanding charge/discharge and regenerative environments, this Nichicon LNC-series part balances high ripple-current capability with compact packaging and a 5000-hour rated life at 85°C.

Key Features

• Capacitance & Voltage — 8200 µF (8.2 mF) nominal capacitance with a 450 V rated voltage and ±20% tolerance.
• High Ripple-Current Performance — Low-frequency ripple current 27.2 A at 120 Hz and high-frequency ripple current 38.08 A at 100 kHz, supporting heavy AC and regenerative loading.
• Endurance & Reliability — Rated load life of 5000 hours at 85°C with requirements for capacitance, tan δ and leakage current met after the endurance test.
• Charge–Discharge Endurance — Meets specified characteristics after 50 million charge–discharge cycles (ΔV = 0.3 × rated voltage, 3 Hz) at room temperature.
• Leakage & Insulation — Leakage current specification up to 5000 µA (5 mA) and insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• Mechanical & Mounting — Screw terminal radial can package (φ76.2 × 185 mm / L: 18.5 × D: 7.62 cm) for secure bolted connections in power assemblies.
• Operating Range & Compliance — Rated for −40°C to +85°C operating temperature and compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies for inverters — Provides bulk energy storage and smoothing for inverter front-ends and DC link circuits in industrial power supplies.
• AC servomotor regenerative circuits — Supports high-frequency regenerative voltages and heavy ripple currents encountered in servo systems.
• General inverter systems — Suited for DC link and energy-recovery functions in general inverter topologies requiring high voltage and high ripple handling.
• High-speed charge–discharge loads — Designed to cope with rapid charge/discharge cycles, as demonstrated by the 50 million cycle endurance test.

Unique Advantages

• High ripple-current capability: Rated for 27.2 A at 120 Hz and 38.08 A at 100 kHz, enabling reliable performance under heavy AC and high-frequency loading.
