LNU2G332MTEG

The LNU2G332MTEG is a screw‑terminal aluminum electrolytic capacitor designed for industrial power electronics. It delivers 3.3 mF capacitance at a 400 V DC rating in a radial can with stud bolt mounting, optimized for inverter and regenerative circuits.

Built for high‑temperature operation and demanding ripple conditions, the LNU series targets industrial power supplies, AC servomotor drives and general inverter systems where high‑voltage capability, high ripple handling and robust lifetime at 105°C are required.

Key Features

• Capacitance & Voltage — 3.3 mF nominal capacitance with a rated voltage of 400 V and ±20% tolerance (120 Hz, 20°C).
• High‑Temperature Endurance — Rated for continuous operation from −40°C to +105°C with a load life of 5000 hours at 105°C under rated ripple conditions.
• High Ripple / High‑Frequency Performance — Ripple current capability of 13.6 A at 120 Hz and 19.04 A at 10 kHz; designed to cope with high‑speed charge/discharge and high‑frequency regenerative voltages.
• Mechanical & Mounting — Radial can with screw terminals and stud bolt mount for secure electrical and mechanical connections in power modules and DC bus assemblies. Physical size: L: 9.5 × D: 6.35 cm.
• Leakage & Insulation — Leakage current after 5 minutes at 20°C meets the datasheet limit of not more than 3√CV (µA) or 5 mA (whichever is smaller); insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — DC bus smoothing and energy buffering in inverter power supplies for industrial equipment.
• Servo Drive Regeneration — Handles high‑frequency regenerative voltage in AC servomotor systems and drives.
• General Inverters — Supports rapid charge/discharge cycles and high ripple currents typical of PWM inverter topologies.
• High‑Power Switching Circuits — Suitable where robust high‑voltage capacitance and repeated charge/discharge endurance are required.

Unique Advantages

• High‑voltage capability in a compact form — 400 V rating and the LNU series’ smaller size (compared to some alternatives) enable dense power module designs.
• Designed for elevated temperatures — 5000‑hour load life at 105°C provides predictable performance in hot operating environments.
• High ripple and high‑frequency tolerance — Specified ripple currents at both 120 Hz and 10 kHz and charge/discharge endurance make it suitable for demanding switching and regenerative duties.
• Robust mounting and electrical connection — Screw terminal / stud bolt mounting simplifies secure installation in industrial assemblies.
• Measured leakage and insulation characteristics — Leakage and insulation resistance specifications support reliable long‑term DC bus performance.
• RoHS compliant — Meets current RoHS restrictions for hazardous substances.
