Overview of LNU2H392MSEHBN – Screw Terminal Aluminum Electrolytic Capacitor, 3900 µF, 500 V

The LNU2H392MSEHBN is a screw‑terminal aluminum electrolytic capacitor engineered for high‑voltage industrial power electronics. It delivers 3.9 mF (3900 µF) nominal capacitance at a 500 V rating, optimized for inverter circuitry, high‑frequency regenerative circuits and other industrial power‑supply applications.

Designed for demanding thermal and electrical environments, this part is rated to 105°C with a rated voltage range up to DC 525 V and a specified load life of 5000 hours under ripple current at 105°C.

Key Features

  • Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a 500 V rated voltage; tolerance ±20% (120 Hz, 20°C). Rated voltage range of the series extends up to DC 525 V.
  • High‑Temperature Endurance — Operates across –40°C to +105°C and is specified for 5000 hours of endurance at 105°C under DC bias plus rated ripple current.
  • High Ripple and HF Performance — Ripple current capability of 12.4 A at 120 Hz and 17.36 A at 10 kHz supports high‑frequency inverter and regenerative loads.
  • Screw Terminal Package — Radial can with screw terminals and separate bracket supply enables secure, low‑impedance connections for power systems.
  • Reliability Tests — Meets insulation resistance, leakage current, and voltage‑proof requirements; qualified for extensive charge–discharge cycling and shelf‑life conditions defined in the product specification.
  • Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

  • Industrial Inverter Power Supplies — Energy buffering and DC link smoothing for general inverters and motor drive front ends.
  • AC Servomotor Regeneration — Handles high‑frequency regenerative voltages in servo and motion control systems.
  • High‑Speed Charge/Discharge Circuits — Supports circuits that require rapid energy transfer and frequent charge–discharge cycling.
  • Industrial Power Electronics — Bulk energy storage and ripple suppression in industrial converters and power conditioning equipment.

Unique Advantages

  • High‑voltage capability: 500 V nominal rating (series up to DC 525 V) enables use in high‑voltage DC link applications.
  • Thermal robustness: Rated to 105°C with a 5000‑hour load life under rated ripple, supporting continuous operation in hot industrial environments.
  • Strong ripple handling: Specified ripple currents of 12.4 A (120 Hz) and 17.36 A (10 kHz) reduce temperature rise and improve system reliability under high AC stress.
  • Secure power connections: Screw‑terminal radial can package provides low‑resistance, mechanically robust terminations suitable for heavy‑current wiring.
  • Designed for frequent cycling: Series endurance includes qualification after extensive charge–discharge cycling, reflecting suitability for rapid energy transfer use cases.
  • RoHS compliant: Meets current RoHS requirements for lead‑restricted manufacturing and procurement.
