LNU2G822MSEJBB

The LNU2G822MSEJBB is an aluminum electrolytic capacitor in a screw-terminal, radial can package designed for high-voltage industrial power applications. With an 8.2 mF capacitance at 400 V DC, this LNU-series part targets inverter circuits, regenerative voltage systems and other industrial power-supply duties that require high ripple handling and elevated temperature endurance.

Key value comes from its combination of high rated voltage, compact LNU-series sizing, long life at 105°C and screw-terminal mounting for secure, low-loss connections in demanding power environments.

Key Features

• Capacitance & Voltage: 8.2 mF (8200 µF) nominal capacitance with a 400 V rated DC voltage and ±20% tolerance (120 Hz, 20°C), providing bulk energy storage for power electronics.
• High-Temperature Endurance: Rated for operation from −40°C to +105°C with a load life of 5000 hours at 105°C when subjected to rated ripple current and DC bias.
• Package & Mounting: Radial can with screw terminals (φ90×125L), designed for robust screw-terminal connections and straightforward mechanical mounting in industrial assemblies.
• Ripple Handling: Specified ripple current capability of 23.1 A at 120 Hz and 32.34 A at 10 kHz to support high-frequency charge–discharge and regenerative circuits.
• Electrical Reliability: Specified tan δ of 0.2 and leakage current limits defined as no more than 3√CV (µA) or 5 mA (whichever is smaller) after 5 minutes at rated voltage; insulation resistance >100 MΩ at DC 500 V between terminal and bracket and AC 2500 V proof for 1 minute between terminal and bracket.
• Endurance & Stability: After 5000 hours at 105°C under rated ripple and DC bias, capacitance remains within 90% ±20% of initial value, tan δ remains ≤200% of initial specified value, and leakage current stays at or below initial specified value.
• Regulatory Compliance: RoHS compliant per the LNU-series documentation.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and energy storage in inverter power supplies and industrial DC link circuits where high voltage and sustained ripple performance are required.
• Motor Drives & Servomotors: Energy buffering and regenerative handling for AC servomotor drives and motor-control inverter systems.
• Inverter Circuits: Support for high-speed charge–discharge cycles and high-frequency regenerative voltages found in general inverter topologies.
• General-Purpose High-Voltage Power Systems: Use where robust, high-voltage capacitance is needed with screw-terminal connectivity for reliable field wiring.

Unique Advantages

• High-Voltage, High-Capacitance Combination: 8200 µF at 400 V delivers substantial DC-link energy in a single component, simplifying design and reducing component count.
• Designed for Elevated Temperatures: 5000-hour life at 105°C under rated ripple and bias gives predictable longevity in hot industrial environments.
• Strong Ripple Performance: Specified ripple current at both low and high frequencies enables use in applications with fast switching and regenerative conditions.
• Secure Screw-Terminal Interface: Screw terminals provide durable, low-resistance connections suited to field wiring and heavy-current paths.
• Robust Electrical Safety Margins: High insulation resistance and AC voltage proof testing between terminal and bracket support reliable operation in high-voltage systems.
• Regulatory Compliance: RoHS compliance addresses restricted substance requirements for industrial electronics.
