LNU2W822MSEH

The LNU2W822MSEH is a screw-terminal aluminum electrolytic capacitor designed for high-voltage industrial power applications. It delivers 8200 µF at a rated voltage of 450 V with polarization and is optimized for inverter and regenerative circuits that demand high ripple handling and robust charge–discharge performance.

Engineered for elevated operating conditions, the device supports operation from −40 °C to +105 °C, a rated-voltage range up to DC 525 V across the LNU series, and a 5000‑hour life under rated ripple current at 105 °C—making it suitable for industrial power supplies, AC servomotor inverters, and other high-frequency regenerative systems.

Key Features

• Capacitance & Voltage: 8200 µF nominal capacitance with a 450 V rated voltage and capacitance tolerance of ±20% (120 Hz, 20 °C).
• High-voltage series capability: Rated voltage range in the LNU series extends up to DC 525 V, supporting high-voltage inverter topologies.
• Wide temperature range: Specified operating temperature from −40 °C to +105 °C for elevated-temperature industrial environments.
• High ripple current handling: Rated ripple current of 25.7 A at 120 Hz and 35.98 A at 10 kHz, supporting heavy ripple loads and high-frequency operation.
• Endurance and life: Load life of 5000 hours at 105 °C with rated ripple current applied; endurance limits specify capacitance, tan δ, and leakage current retention criteria after test.
• Charge–discharge durability: Designed to meet series endurance after 50 million charge–discharge cycles (ΔV = rated voltage ±0.3, 3 Hz cycle) with defined limits on capacitance, tan δ, and leakage.
• Screw-terminal package: Radial can with screw terminals for secure bolted connections, suitable for robust industrial mounting and high-current termination.
• Insulation & voltage proof: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; passes AC 2500 V for 1 minute with no abnormality.
• Leakage current specification: After 5 minutes at rated voltage and 20 °C, leakage current not more than 3√(C·V) µA or 5 mA, whichever is smaller (C in µF, V in V).
• RoHS compliant: Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).
• Compact series design: LNU series offers higher-voltage capability in a smaller footprint compared with earlier LNT designs.
• Form factor: Size dimension L: 19.5 × D: 7.62 cm (radial can with screw terminals).

Typical Applications

• Industrial inverters: Bulk and smoothing capacitor for inverter circuitry in industrial power supplies where high voltage and long life are required.
• AC servomotor systems: Energy buffering and regenerative-voltage handling in high-frequency regenerative circuits for servomotors.
• High-frequency power electronics: Support for circuits requiring high ripple-current capability and rapid charge–discharge cycles.

Unique Advantages

• High-voltage capability: Rated at 450 V with series coverage up to DC 525 V—allows use in high-voltage power stages without series stacking.
• High ripple and frequency performance: Specified ripple current at both 120 Hz and 10 kHz supports low-frequency smoothing and high-frequency switching environments.
• Robust thermal endurance: 5000 hours at 105 °C under rated ripple current provides predictable lifetime performance in elevated-temperature installations.
• Durable screw-terminal termination: Bolted connections provide secure, low-resistance terminations for high-current and vibration-prone environments.
• Charge–discharge reliability: Qualified for extensive charge–discharge cycling (50 million cycles at defined conditions), addressing demanding regenerative and pulsed-power loads.
• Compliance and manufacturability: RoHS compliance and standardized radial screw-terminal package ease integration into industrial assemblies.
