LNX2J392MSEJ

The LNX2J392MSEJ is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage, high-capacitance power applications. It provides 3.9 mF capacitance at a 630 V rating with robust screw-terminal connections suitable for industrial power electronics.

Engineered for general-purpose and inverter-related power supply duties, this capacitor combines high ripple-current capability and a wide operating temperature range for reliable DC-link smoothing and bulk energy storage in high-voltage systems.

Key Features

• Capacitance & Voltage — 3.9 mF rated capacitance at 630 V, delivering significant energy storage for high-voltage power rails.
• High Ripple Current Handling — Rated ripple current of 17.3 A at 120 Hz and 24.22 A at 100 kHz to support demanding AC ripple conditions.
• Screw-Terminal Mounting — Radial can with screw terminals for secure electrical connection and simplified installation in power racks or bus assemblies.
• Package & Dimensions — φ90 × 190 L radial can; size dimension listed as L: 19 × D: 9 cm for planning mechanical integration.
• Operating Temperature & Lifetime — Specified operating range of −25 °C to +85 °C with a rated lifetime of 2000 hours at +85 °C.
• Polarized with Standard Tolerance — Polarized capacitor with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Leakage Current Specification — Per series datasheet, leakage after 5 minutes’ application of rated voltage is not more than 3√CV (µA) or 5 mA, whichever is smaller (at 20 °C).
• RoHS Compliant — Meets RoHS directive requirements as indicated in product data.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy buffering in high-voltage industrial supplies and converters.
• Inverter and Motor Drive Systems — DC-link and ripple suppression for inverter circuitry and motor drive power stages.
• High-Voltage Power Conversion — Energy storage and filtering in high-voltage converter and power conditioning units where elevated voltage and ripple handling are required.
• General-Purpose Power Electronics — Applications requiring large capacitance and robust terminations for reliable DC performance.

Unique Advantages

• High-voltage, high-capacitance combination: 3.9 mF at 630 V supports significant DC energy storage without parallel stacking of multiple lower-voltage capacitors.
• Robust screw-terminal connections: Secure mechanical and electrical terminations designed for high-current, high-reliability assemblies.
• Demonstrated ripple endurance: Specified ripple current ratings at both low and high frequencies allow designers to size capacitors confidently for expected ripple loads.
• Compact radial can footprint: φ90 × 190 L package and defined size dimensions (L: 19 × D: 9 cm) simplify mechanical planning for enclosures and mounting hardware.
• Designed for higher-temperature operation: Rated to operate from −25 °C to +85 °C with specified lifetime at +85 °C for predictable in-service behavior.
• Compliance-ready: RoHS conformity supports regulatory and environmental requirements in many regional markets.
