LNU2W822MSEJBB

The LNU2W822MSEJBB is an aluminum electrolytic capacitor from Nichicon’s LNU series, featuring a screw-terminal radial can construction. It delivers 8200 µF at a 450 V DC rating with ±20% capacitance tolerance and is designed for high-voltage industrial power applications.

With a -40°C to 105°C operating range, a 5000-hour rated life at 105°C, and high ripple-current capability, this part is suited for inverter circuitry, regenerative motor drives and other industrial power systems that require robust DC-link energy storage and frequent charge–discharge handling.

Key Features

• Capacitance & Voltage — 8200 µF nominal capacitance at a 450 V DC rating with ±20% tolerance (120 Hz, 20°C).
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-resistance electrical connections and reliable mechanical mounting in industrial assemblies.
• High Ripple Current Capability — Rated ripple current of 24.7 A at 120 Hz (low frequency) and 34.58 A at 10 kHz (high frequency) to support heavy ripple loading in power conversion circuits.
• High-Temperature Endurance — Specified for operation from -40°C to 105°C with a load-life rating of 5000 hours at 105°C under rated ripple and DC bias.
• Leakage & Dissipation — Leakage current specified at 5000 µA and a loss tangent (tan δ) of 0.2 to characterize dielectric losses.
• Electrical Insulation & Voltage Proof — Meets insulation resistance requirements (more than 100 MΩ at DC 500 V between terminal and bracket) and withstands AC 2500 V for 1 minute between terminal and bracket.
• Form Factor & Packaging — Compact φ90 × 145L footprint (L: 14.5 cm × D: 9 cm), cardboard packing; mass production status for sustained availability.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Inverters & Motor Drives — DC-link smoothing and energy buffering for inverter circuitry and AC servomotor regenerative circuits where high-voltage and high-ripple handling are required.
• Industrial Power Supplies — Bulk energy storage and ripple suppression in high-voltage power supplies used in factory automation and power conversion equipment.
• High-Speed Charge–Discharge Systems — Applications that require frequent charge–discharge cycles and robust endurance under repeated stress.
• Regenerative Power Circuits — Handling of high-frequency regenerative voltages in motor control and drive systems.

Unique Advantages

• High-voltage capability in a compact can — 450 V rating with a φ90 × 145L footprint helps integrate high-voltage capacitance into space-constrained power assemblies.
• Designed for heavy ripple environments — High low- and high-frequency ripple current ratings help maintain performance and thermal stability in demanding power-conversion applications.
• Long-term thermal reliability — 5000 hours rated life at 105°C under specified conditions supports sustained operation in elevated-temperature industrial environments.
• Robust, serviceable connections — Screw-terminal construction provides secure electrical and mechanical attachments suitable for field service and heavy-current interconnections.
• Measurable insulation and voltage proof characteristics — Insulation resistance and voltage-withstand properties provide predictable safety margins for system designers.
• Production-ready and compliant — Cardboard packing and mass production status with RoHS compliance simplify procurement and regulatory planning.
