LNX2W392MSEGBN

The LNX2W392MSEGBN is an aluminum electrolytic capacitor in Nichicon's LNX series, configured with a screw-terminal radial can for secure, high-current connections. It provides 3.9 mF capacitance at a 450 V rating and is designed for industrial power applications.

Engineered for high ripple environments and extra-high-voltage use, this part delivers long operational life at elevated temperature and is RoHS compliant. Typical use cases include industrial power supplies and inverter circuitry where high ripple capability and reliability are required.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a 450 V rated voltage for extra-high-voltage applications.
• High ripple capability — Rated ripple current of 11.4 A at 120 Hz and 15.96 A at 100 kHz to support demanding power circuits.
• Long ripple-life endurance — Specified for 20,000 hours of standard ripple-current application at +85°C (endurance conditions in datasheet).
• Screw-terminal radial can package — Screw terminal mounting and radial can package provide secure electrical and mechanical connections for high-current installations.
• Operating temperature range — Rated for -25 °C to +85 °C operation to cover typical industrial ambient ranges.
• Leakage current specification — After 5 minutes at rated voltage and 20 °C, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller (per datasheet).
• Capacitance tolerance — ±20% at 120 Hz, 20 °C.
• RoHS compliance & flame-retardant option — Compliant to RoHS directives; flame retardant electrolyte is available for applicable types in the series.
• Series design continuity — Part of the LNX series, which supports extended dimensional options within the series range.

Typical Applications

• Industrial power supplies — Suited for use in industrial power supplies, including inverter circuitry where sustained ripple performance is needed.
• Extra‑high‑voltage, high‑ripple circuits — Intended for circuits that require both elevated voltage rating and high ripple-current handling.
• General-purpose power systems — Applicable where a robust, high-capacitance, polarized aluminum electrolytic is required for energy storage or smoothing.

Unique Advantages

• Long operational life under ripple stress — Rated for 20,000 hours at +85 °C under standard ripple conditions, supporting extended service intervals.
• High ripple-current handling — Explicit ripple current ratings at 120 Hz and 100 kHz provide quantifiable performance for thermal and ripple-design decisions.
• Extra-high-voltage rating — 450 V nominal rating enables use in higher-voltage power architectures without stacking.
• Robust mechanical connection — Screw-terminal radial-can construction simplifies mounting and delivers reliable high-current terminations.
• Measured leakage limits — Datasheet-defined leakage current formula gives deterministic bounds for standby and charged-state behavior.
• Regulatory and safety-oriented options — RoHS compliance and availability of flame-retardant electrolyte types address environmental and safety considerations.
