LNX2G392MSEGBB

The LNX2G392MSEGBB from Nichicon is a screw‑terminal, radial can aluminum electrolytic capacitor rated at 3,900 µF (3.9 mF) and 400 V. It belongs to the LNX series designed for high‑ripple, extra‑high‑voltage applications and is suited for industrial power supplies and inverter circuitry.

With a long rated life and robust thermal range, this capacitor targets engineers needing high energy storage, high ripple handling and reliable long‑term operation in demanding power conversion environments.

Key Features

• Capacitance & Voltage — 3,900 µF (3.9 mF) nominal capacitance with a 400 V rated voltage and ±20% tolerance for bulk energy storage in high‑voltage circuits.
• High Ripple Handling — Rated ripple current of 11 A at 120 Hz and 15.4 A at 100 kHz to support applications with significant AC ripple components.
• Long Endurance — Designed for 20,000 hours of operation at 85°C under rated ripple current, supporting extended operational life in continuous power systems.
• Operating Temperature Range — Specified for −25°C to +85°C to accommodate a wide range of industrial ambient conditions.
• Screw Terminal, Radial Can Package — Robust screw‑terminal construction (radial can with screw terminals) for secure, low‑impedance connections; nominal bolt size for the φ63.5 package is M5.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller (measured at 20°C), enabling predictable bias behavior.
• RoHS Compliant — Conforms to RoHS directive requirements.
• Physical Size — φ63.5 × 150 mm (L: 15.0 cm × D: 6.35 cm) package for designs where high capacitance and high voltage are required.

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy buffering in industrial power systems and inverter power stages.
• Inverter Circuitry — Energy storage and ripple smoothing in inverter front‑end and DC link circuits where high voltage and high ripple capability are needed.
• High‑Voltage Power Conversion — Use in extra‑high‑voltage power conversion modules where long life under ripple stress is required.
• General‑Purpose Power Filtering — General purpose smoothing and decoupling in high‑energy, high‑voltage applications.

Unique Advantages

• Extended life at elevated temperature: 20,000 hours at 85°C under rated ripple current reduces maintenance and replacement frequency in continuous‑duty systems.
• High ripple capability: 11 A (120 Hz) and 15.4 A (100 kHz) ratings support heavy AC ripple environments common in power conversion.
• High voltage rating for extra‑high‑voltage use: 400 V rating provides headroom for high‑voltage DC link and converter topologies.
• Secure screw‑terminal connections: Radial can with screw terminals and M5 nominal terminal bolt for robust mechanical and electrical mounting.
• Predictable leakage behavior: Clear leakage current limit (3√CV µA or 5 mA) enables reliable sizing of bleeder networks and bias control.
• RoHS compliance: Meets environmental restrictions for lead‑free materials.
