LNU2G822MSEH

The LNU2G822MSEH is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNU series, rated at 8200 µF and 400 V with a 105°C maximum operating temperature. It combines high-voltage capability with a design intended for industrial power electronics where robust ripple handling and long-term endurance are required.

Typical use cases include industrial power supplies, inverter circuitry and regenerative systems for AC servomotors and similar equipment where high ripple current tolerance and extended high-temperature life are important design considerations.

Key Features

• Electrical rating — 8200 µF nominal capacitance at 400 V DC with ±20% tolerance (120 Hz, 20°C), suitable for high-voltage DC bus applications.
• High ripple current capability — Low-frequency ripple current of 24.2 A (120 Hz) and high-frequency ripple current of 33.88 A (10 kHz) to support power conversion and charge–discharge loading.
• Endurance and reliability — Rated load life of 5000 hours at 105°C under DC bias plus rated ripple current; meets the LNU series endurance characteristics for capacitance, tan δ and leakage after endurance testing.
• Thermal range — Operating temperature from −40°C to +105°C for compatibility with demanding industrial environments.
• Leakage and loss characteristics — Specified leakage current up to 5000 µA and design tangent of loss angle (tan δ) of 0.2 to characterize dissipation.
• Mechanical & mounting — Screw-terminal radial can package (φ76.2 × 170 mm / L: 17 cm × D: 7.62 cm) for secure bolted connections; mounting brackets supplied separately.
• RoHS compliant — Conforms to applicable RoHS directive requirements.

Typical Applications

• Industrial inverters — Bulk DC bus smoothing and energy buffering for inverter systems used in motor drives and industrial automation.
• Regenerative power systems — Handling high-frequency regenerative voltages and frequent charge–discharge cycles in AC servomotor drives.
• High-voltage power supplies — Energy storage and ripple suppression in high-voltage power conversion and distribution equipment.
• General-purpose power electronics — Where a high-capacitance, high-voltage screw-terminal capacitor with extended high-temperature life is required.

Unique Advantages

• High-voltage capability in a compact package — 400 V rating with a relatively compact screw-terminal can (φ76.2 × 170 mm) for space-conscious power designs.
• Designed for heavy ripple loading — Specified ripple currents at both 120 Hz and 10 kHz enable use in applications with significant low- and high-frequency ripple components.
• Long high-temperature endurance — 5000 hours rated life at 105°C under specified test conditions provides predictable performance over prolonged elevated-temperature operation.
• Screw-terminal mounting — Robust, bolted connections simplify installation and support secure current-carrying terminations in industrial assemblies.
• Measurable dissipation and leakage limits — Defined tan δ (0.2) and leakage current limit (5000 µA) for predictable electrical behavior in system-level thermal and loss budgets.
• RoHS compliance — Meets regulatory requirements for restricted substances.
