LNU2W272MSEGBN

The LNU2W272MSEGBN is a screw-terminal aluminum electrolytic capacitor designed for high-voltage industrial power electronics. It pairs a 2.7 mF capacitance with a 450 V DC rating in a smaller-sized 105°C screw-terminal package optimized for inverter and regenerative-power applications.

Engineered for sustained ripple loading and high-speed charge–discharge behavior, this part delivers long operating life and high ripple-current capability for industrial inverter, servo drive, and general power-supply designs.

Key Features

• Package & Mounting — Screw terminal, radial can with screw terminals for secure, serviceable connections in power assemblies.
• Rated Voltage & Capacitance — 450 V DC rated with 2.7 mF capacitance and ±20% tolerance, suitable for high-voltage energy storage and filtering.
• High Temperature Endurance — Rated for operation from −40°C to +105°C with a load life of 5000 hours at 105°C under applied ripple current.
• High Ripple Current — 13.1 A at 120 Hz and 18.34 A at 10 kHz, supporting heavy AC ripple and high-frequency operation common in inverter systems.
• Designed for Fast Charge–Discharge — Built to cope with high-speed charge–discharge loading and high-frequency regenerative voltages.
• Compact Footprint — Smaller-sized than the LNT series while providing high-voltage capability; physical size L: 10 × D: 6.35 cm with a seated height of 3.937 inches.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — Energy storage and DC-link filtering for inverter circuitry in industrial power supplies.
• AC Servo Motor Drives — Filtering and regenerative energy handling for AC servomotor drives.
