LNX2G392MSEHBN

The LNX2G392MSEHBN is a screw‑terminal aluminum electrolytic capacitor designed for high‑voltage power applications. It combines a large 3.9 mF capacitance with a 400 V rated voltage in a φ76.2 × 100L can with secure screw terminals for robust electrical and mechanical connections.

Targeted at industrial power systems and inverter circuitry, this part delivers high ripple handling and long endurance—making it suitable where sustained ripple current and long operational life at elevated temperature are required.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a 400 V rated voltage and ±20% tolerance, suitable for energy storage and smoothing in high‑voltage circuits.
• High Ripple Current — Rated ripple current of 10.5 A at 120 Hz (low frequency) and 14.7 A at 100 kHz (high frequency), enabling use on heavy‑ripple DC buses and power converter outputs.
• Long Endurance — Designed for 20,000 hours of life at +85°C under rated ripple current, supporting extended field service intervals and reliable long‑term operation.
• Low Losses — Specified tanδ (DF) of 0.2 at 20°C and 120 Hz for predictable dissipation characteristics in filtering and energy‑storage roles.
• Controlled Leakage — Leakage current specified at 3740 µA, enabling predictable standby and post‑application behavior.
• Robust Mechanical Package — Screw terminal radial can (φ76.2 × 100L) with M5 bolt nominal terminal diameter for secure mounting and heavy‑current connections; packed in cardboard for mass production handling.
• Operating Range & Compliance — Operating temperature −25°C to +85°C and RoHS compliant.

Typical Applications

• Industrial Power Supplies — Suited for inverter circuitry and similar industrial supply designs that require large capacitance and high ripple current capability.
• High‑Voltage Power Electronics — Designed for extra‑high voltage applications within the LNX series' rated voltage range, providing energy storage and smoothing on 350–550 V class systems.
• General‑Purpose Power Systems — Use where a polarized, high‑capacitance screw‑terminal capacitor with long life and RoHS compliance is needed.

Unique Advantages

• High ripple handling: 10.5 A at 120 Hz and 14.7 A at 100 kHz allow the capacitor to tolerate significant AC stress on DC rails and converter outputs.
• Extended operational life: 20,000 hours at +85°C under rated ripple current reduces maintenance and replacement frequency in continuous‑duty systems.
• Large energy density at elevated voltage: 3.9 mF at 400 V provides substantial energy storage for smoothing and transient support in high‑voltage circuits.
• Secure screw‑terminal mounting: M5 nominal terminal diameter and a radial can package deliver solid mechanical and electrical connections for high‑current installations.
• Predictable electrical behaviour: Low tanδ and specified leakage current support deterministic thermal and leakage budgeting in design.
• Production readiness: Cardboard packing and mass production status help ensure supply continuity for volume designs.
