Overview of LNK2H392MSEH – Aluminum Electrolytic Capacitor, Screw Terminal, 3.9 mF / 500 V

The LNK2H392MSEH is a Nichicon screw-terminal aluminum electrolytic capacitor with a rated capacitance of 3.9 mF (3900 µF) at 500 V. Designed as a general-purpose, high-voltage electrolytic in a screw-terminal can, it targets applications requiring bulk energy storage and high-voltage filtering where a robust, serviceable mounting is preferred.

Key value comes from its combination of high voltage rating, substantial capacitance, substantial ripple-handling capability, and a 5000-hour rated life at 85°C, providing dependable performance in industrial and power-electronics environments.

Key Features

  • High voltage, high capacitance — 3.9 mF (3900 µF) rated at 500 V for bulk energy storage and high-voltage filtering.
  • Screw terminal mounting — Radial can with screw terminals (suitable for M5 bolt mounting) simplifies installation and mechanical retention in power assemblies.
  • Rated ripple current — 14.4 A at 120 Hz and 20.16 A at 10 kHz, supporting substantial AC ripple loads where high-frequency and low-frequency ripple dissipation are required.
  • Endurance and temperature — 5000 h life at 85°C and rated operating range of −25°C to +85°C for sustained operation under elevated temperatures.
  • Leakage and loss characteristics — Specified leakage current 4180 µA and tangent of loss angle (tan δ) 0.2, allowing designers to size bleed networks and loss budgets accurately.
  • Electrical safety and insulation — Insulation resistance greater than 100 MΩ at DC 500 V and no abnormality under AC 2500 V for 1 minute between terminal and bracket as specified in the datasheet.
  • Packaging and production — Cardboard packing and mass-production availability for consistent supply and handling.
  • Regulatory — RoHS compliant.

Typical Applications

  • Power supplies — Bulk smoothing and energy buffering in high-voltage power supply stages where 500 V rating and 3.9 mF capacitance are required.
  • Power conversion equipment — DC-link and filtering roles in industrial converters and inverters that demand high-voltage capacitive energy storage and substantial ripple handling.
  • Industrial electronics — General-purpose high-voltage filtering and decoupling for control gear and power-conditioning systems within the −25°C to +85°C operating window.

Unique Advantages

  • High-voltage capability: 500 V rating enables use in higher-voltage circuits without series stacking of lower-voltage parts.
  • Large stored energy: 3.9 mF capacitance provides significant bulk energy for smoothing and ride-through in power systems.
  • Robust ripple performance: Specified ripple currents at both 120 Hz and 10 kHz support mixed-frequency ripple environments and reduce thermal stress in high-duty applications.
  • Serviceable mechanical interface: Screw-terminal construction with M5 nominal bolt diameter allows secure, repeatable connections suitable for maintenance-focused installations.
  • Validated endurance: 5000 hours at 85°C under rated ripple and bias gives a measurable lifetime baseline for thermal and reliability planning.
  • Measured electrical characteristics: Specified leakage current, tan δ, and insulation resistance let engineers quantify leakage, dielectric loss, and isolation behavior during system design.

Why Choose LNK2H392MSEH?

LNK2H392MSEH from Nichicon positions itself as a durable, high-voltage electrolytic solution for designs that require substantial capacitance, reliable ripple handling, and a screw-terminal mechanical interface. Its combination of 3.9 mF at 500 V, defined leakage and loss parameters, and a 5000-hour rated life at 85°C enables engineers to plan for performance and longevity in demanding power-electronics applications.

This capacitor is well suited for engineers and procurement teams specifying components for industrial power supplies, converters, and other general-purpose high-voltage systems where serviceable mounting, RoHS compliance, and predictable electrical characteristics are important.
