LNT2G392MSEHBN

The LNT2G392MSEHBN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, offering 3.9 mF capacitance at a 400 V rating. Designed for general-purpose power-electronic applications, it provides high ripple-current capability and extended endurance for sustained operation up to +105°C.

Its screw-terminal radial can package (φ76.2 × 110L) and RoHS compliance make it suitable for production deployments where secure connections, long life, and reliable bulk capacitance are required.

Key Features

• High Capacitance / Voltage: 3.9 mF (3900 µF) nominal capacitance with a 400 V rated voltage, providing substantial energy storage in a single radial can package.
• Screw Terminal Mounting: Robust screw-terminal connections (radial, can with screw terminals) for secure, low-resistance electrical and mechanical termination.
• Endurance at Elevated Temperature: Rated for 5,000 hours life at +105°C under specified ripple conditions, supporting long-term operation in hot environments.
• High Ripple Current Capability: 18.2 A at 120 Hz (low frequency) and 25.48 A at 100 kHz (high frequency) to handle demanding AC ripple and switching currents in power circuits.
• Controlled Dissipation Factor: tan δ = 0.2 (maximum) measured at 20°C and 120 Hz, indicating predictable AC loss characteristics.
• Leakage Current Specification: Typical leakage current listed as 3740 µA after rated voltage application, enabling designers to budget DC losses accurately.
• Wide Operating Temperature Range: Specified for operation from −25°C to +105°C for the 160 to 500 V voltage class.
• Packaging and Availability: Supplied in cardboard packing and available in mass production quantities for volume manufacturing.
• RoHS Compliant: Conforms to RoHS requirements as indicated in the product information.
• Physical Size: Cylinder dimensions φ76.2 × 110L (L: 11 cm × D: 7.62 cm) for straightforward mechanical integration.

Typical Applications

• Power Supply DC Link and Smoothing: Bulk capacitance and 400 V rating make this capacitor appropriate for energy storage and smoothing in high-voltage power supplies and DC link circuits.
• Industrial Power Electronics: High ripple-current capability and extended 105°C endurance support use in industrial inverters, motor drives, and switching power modules.
• High-Voltage Filtering: Use in high-voltage filter stages where stable capacitance, controlled tan δ, and defined leakage current are required for predictable system behavior.

Unique Advantages

• High energy density at 400 V: Combines 3.9 mF capacitance with a 400 V rating to reduce the number of parts needed for bulk storage.
• Designed for sustained thermal stress: 5,000-hour rated life at +105°C under rated ripple conditions provides predictable lifetime performance in hot operating environments.
• Engineered for high ripple environments: Significant low- and high-frequency ripple current ratings (18.2 A at 120 Hz, 25.48 A at 100 kHz) help maintain capacitance and thermal stability under switching loads.
• Secure, serviceable terminations: Screw terminals enable reliable bolted connections and ease of installation or replacement in field service scenarios.
• Clear electrical characterization: Specified tan δ (0.2 at 20°C/120 Hz) and documented leakage current (3740 µA) aid accurate thermal and loss budgeting in designs.
• Production-ready supply: Cardboard packing and mass-production status support volume procurement and streamlined assembly workflows.
