LNX2W392MSEHBB

The LNX2W392MSEHBB is an aluminum electrolytic capacitor in a screw-terminal radial can package designed for extra‑high voltage, high‑ripple applications. With a rated capacitance of 3900 µF at 450 V and an operating range of −25 °C to +85 °C, it targets industrial power electronics where high ripple current and long operational life are required.

Typical use includes industrial power supplies and inverter circuitry; the part is engineered for reliability with a demonstrated lifetime of 20,000 hours when operated at rated ripple current at +85 °C.

Key Features

• Capacitance & Voltage: 3.9 mF (3900 µF) nominal capacitance with a 450 V rated voltage for extra‑high‑voltage DC link and smoothing duties.
• High ripple capability: Rated ripple current of 11.2 A at 120 Hz and 15.68 A at 100 kHz to support demanding power‑conversion workloads.
• Long life at elevated temperature: Endurance rated for 20,000 hours at +85 °C when operated at the rated ripple current and peak voltage not exceeding the rated voltage.
• Robust mounting and terminals: Screw terminal radial can package provides secure, low‑impedance connections suitable for heavy current installations.
• Wide operating range: Specified operating temperature from −25 °C to +85 °C for industrial environments.
• Leakage current specification: After 5 minutes at rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA, whichever is smaller (C in µF, V in V).
• Tolerance and polarization: Capacitance tolerance ±20% (at 120 Hz, 20 °C); polarized device suitable for DC applications.
• Safety and compliance: Flame‑retardant electrolyte option available; compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Physical dimensions: Package dimensions L: 13 cm × D: 7.62 cm with a maximum seated height of 5.118 inch, enabling large capacitance in a screw‑terminal can form factor.

Typical Applications

• Industrial power supplies: Bulk energy storage and smoothing in power supplies used for industrial equipment and control systems.
• Inverter circuitry: DC link and smoothing capacitor for inverter stages where high ripple current and extra‑high voltage capability are required.
• High‑voltage power conversion: Applications demanding sustained performance under high DC voltages and elevated temperature over long lifetimes.

Unique Advantages

• Extended operational life: Rated for 20,000 hours at +85 °C under rated ripple conditions, reducing maintenance and replacement frequency in continuous‑duty systems.
• High ripple tolerance: Clear ripple current ratings at both low and high frequencies (11.2 A at 120 Hz; 15.68 A at 100 kHz) to support a range of converter topologies.
• Screw‑terminal reliability: Screw terminals provide mechanically secure, low‑resistance connections for high‑current assemblies and easier field wiring or replacement.
• Extra‑high voltage capability: 450 V rating suits DC link and high‑voltage smoothing roles without exceeding the specified peak voltage.
• Regulatory and safety options: RoHS compliance and availability of flame‑retardant electrolyte help address environmental and safety considerations.
• Predictable leakage behavior: Specified leakage current limits after initial voltage application help designers manage standby and bias current budgets.
