LNT2W392MSEG

The LNT2W392MSEG from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series, designed for high-voltage, high-ripple applications. It provides 3.9 mF capacitance at a 450 V rating with a ±20% tolerance and is configured as a polarized, radial can with screw terminals.

Engineered for demanding power systems, this component delivers high ripple-current capability, 5,000 hours endurance at 105°C, and RoHS compliance, making it suited to general-purpose industrial and power electronics designs that require robust DC energy storage and smoothing.

Key Features

• Capacitance & Voltage — 3.9 mF nominal capacitance rated at 450 V with ±20% tolerance for bulk energy storage and DC-link applications.
• High Ripple Current — 18.3 A at 120 Hz (low frequency) and 25.62 A at 100 kHz (high frequency) to handle substantial AC ripple on DC buses.
• Endurance and Temperature — 5,000 hours load life at +105°C when rated ripple current is applied; operating temperature range −25°C to +105°C (per series specifications for 160–500 V).
• Leakage and Dissipation — Specified leakage current of 3970 µA and tanδ (DF) 0.2 for stable electrical characteristics under rated conditions.
• Package & Mounting — Radial can with screw terminals (φ63.5 × 170L; L: 17 × D: 6.35 cm) designed for secure bolted connections and ease of installation.
• Compliance & Production — RoHS-compliant and available in mass production with cardboard packing.

Typical Applications

• High-voltage DC-link and bulk smoothing — 450 V rating and high ripple-current capability support energy buffering and smoothing on DC bus circuits.
• Power conversion equipment — Suitable for power supplies and inverter DC-link stages where sustained ripple current and 105°C endurance are required.
• Industrial power electronics — Used in industrial controllers and converters requiring robust capacitance and long-term stability under elevated temperature and ripple stress.

Unique Advantages

• High ripple-current capability: Supports demanding AC ripple loads with specified 18.3 A (120 Hz) and 25.62 A (100 kHz) ratings to reduce thermal stress and increase system reliability.
• Long endurance at elevated temperature: Rated for 5,000 hours at +105°C under applied rated ripple current, providing predictable long-term performance in hot operating environments.
• Robust screw-terminal mounting: Screw terminals and a large-diameter radial can (φ63.5 × 170L) enable secure mechanical and electrical connections for high-power systems.
• Clear electrical specifications: Defined leakage current (3970 µA) and tanδ (0.2) allow engineers to budget losses and leakage precisely in designs.
• Production-ready and compliant: RoHS-compliant and in mass production with cardboard packing for straightforward procurement and assembly handling.
