LNU2H822MTEJ

The LNU2H822MTEJ is an aluminum electrolytic capacitor in Nichicon's LNU series, configured for stud bolt (screw terminal) mounting. It provides 8.2 mF capacitance at a 500 V DC rating and is designed for demanding industrial power applications that require high-voltage energy storage and high ripple handling.

With a 105°C maximum operating temperature and a rated life of 5000 hours at that temperature, this capacitor is intended for use in inverter circuitry, high-frequency regenerative voltage applications such as AC servomotors, and other general-purpose industrial power-supply systems where sustained ripple current and robust endurance are required.

Key Features

• Electrical Performance — 8.2 mF (8200 µF) capacitance with ±20% tolerance and a 500 V rated voltage for high-voltage DC energy storage.
• Low Loss Characteristic — Specified tan δ (DF) of 0.2 measured at 20°C, 120 Hz to indicate dissipation behavior under standard test conditions.
• High Ripple Capability — Supports 20.2 A low-frequency ripple current at 120 Hz and 28.28 A high-frequency ripple at 10 kHz for demanding AC and DC-link applications.
• Robust Endurance — Rated life of 5000 hours at 105°C under applied ripple current; designed for continuous operation in elevated-temperature environments.
• Mechanical & Mounting — Stud bolt mount with screw terminals in a radial can package (φ90 × 205 mm length) for secure, low-inductance electrical connection.
• Polarized, General-Purpose — Polarized electrolytic construction for general-purpose industrial power electronics.
• Compliance & Packaging — RoHS-compliant; supplied in cardboard packing and available in mass production status.

Typical Applications

• Industrial Inverters & Motor Drives — DC-link and smoothing in inverter circuitry for AC servomotors and drive systems, leveraging the 500 V rating and high ripple capability.
• Regenerative Power Systems — Energy buffering for high-frequency regenerative voltage in applications where rapid charge–discharge and sustained ripple current are required.
• Power Supplies — Bulk energy storage and ripple filtering in high-voltage power supplies used in industrial equipment and power-conversion systems.
• High-Speed Charge–Discharge Circuits — Suitable for applications that require repeated high-speed charge–discharge cycles; the LNU series includes endurance tests for charge–discharge behavior.

Unique Advantages

• High-Voltage Energy Storage: 500 V rating with 8.2 mF capacitance provides substantial DC energy storage for high-voltage power designs.
• Designed for Elevated Temperatures: 105°C operating limit and 5000-hour rated life at that temperature support long-term use in hot industrial environments.
• High Ripple Handling: Specified ripple currents at both 120 Hz and 10 kHz address both low- and high-frequency stress in inverter and regenerative circuits.
• Secure, Low-Inductance Mounting: Stud bolt screw-terminal construction enables robust electrical connections and mechanical stability for power systems.
• Series-Level Reliability Testing: LNU series endurance and charge–discharge qualifications provide verifiable behavior after extended ripple and cycling exposure.
• RoHS Compliant: Meets RoHS requirements for environmental compliance in industrial component selection.
