Overview of LNX2H392MSEH – Screw Terminal Aluminum Electrolytic Capacitor, 3.9 mF, 500 V

The Nichicon LNX2H392MSEH is an aluminum electrolytic capacitor in a screw-terminal, radial can package designed for high-voltage, high-ripple applications. With a rated capacitance of 3.9 mF (3900 µF) at 500 V and a specified operating temperature range of -25°C to 85°C, it targets industrial power supplies and inverter circuitry where high ripple handling and long endurance are required.

This part is in mass production and offers a combination of high ripple current capability, long endurance at elevated temperature (5000 hours at 85°C for 500 V parts), and secure screw-terminal mounting for robust electrical connections.

Key Features

  • High Voltage Rating — Rated at 500 V to support extra-high-voltage DC link and power conversion applications.
  • Large Capacitance — 3.9 mF (3900 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C for energy storage and smoothing.
  • High Ripple Current Performance — 12.1 A at 120 Hz (low frequency) and 16.94 A at 100 kHz (high frequency), enabling effective ripple handling in power stages.
  • Electrical Loss and Leakage — Specified tan δ of 0.2 at 20°C and 120 Hz, and leakage current of 4180 µA, allowing predictable loss and DC leakage behavior.
  • Endurance at Elevated Temperature — Rated for 5000 hours at 85°C under the specified test conditions for 500 V parts, supporting long-term operation in industrial environments.
  • Rugged Mechanical Termination — Screw terminal mounting and radial can package provide secure, low-resistance connections for high-current installations.
  • RoHS Compliant — Conforms to RoHS requirements, suitable for use in regulated manufacturing environments.
  • Compact High-Capacitance Form Factor — Physical size φ76.2 × 150 mm (D × L) for designers specifying large capacitance in a defined envelope.

Typical Applications

  • Industrial Power Supplies — Bulk smoothing and energy storage for high-voltage supply rails and power conversion systems.
  • Inverter Circuits — DC link and ripple absorption in inverter and motor-drive electronics where high ripple current capability is required.
  • General-Purpose High-Voltage Smoothing — Use in industrial equipment and power subsystems requiring 500 V rated capacitance and long-term endurance.

Unique Advantages

  • High Ripple Capacity: Explicit low- and high-frequency ripple ratings (12.1 A at 120 Hz; 16.94 A at 100 kHz) support sustained ripple currents without immediate degradation.
  • Long Endurance at 85°C: 5000-hour rated life at 85°C (for 500 V parts) gives predictable performance over extended operating periods in harsh thermal environments.
  • Secure Screw-Terminal Connection: Screw terminals deliver robust mechanical and electrical attachment ideal for high-current industrial wiring.
  • High Voltage and Large Capacitance: 500 V rating combined with 3.9 mF capacitance provides substantial stored energy for DC link and smoothing applications.
  • Measured Electrical Characteristics: Specified tan δ (0.2 at 20°C, 120 Hz) and stated leakage current (4180 µA) allow engineering teams to model losses and standby leakage precisely.
  • Production-Ready: Mass production status ensures availability for volume designs and manufacturing planning.
