LNT2G392MSEHBB

The LNT2G392MSEHBB is an aluminum electrolytic capacitor in a screw-terminal, radial can package, offering 3900 µF capacitance at a 400 V rated voltage with a 105°C maximum operating temperature. It is part of Nichicon's LNT series designed for high-ripple, high-voltage applications where secure screw-terminal mounting and long operational life are required.

This device is specified for general-purpose applications that require high capacitance and sustained performance at elevated temperatures, featuring a rated load life of 5,000 hours at 105°C and RoHS compliance.

Key Features

• High Capacitance and Voltage — 3.9 mF (3900 µF) nominal capacitance at a 400 V rated voltage, providing significant energy storage for high-voltage circuits.
• 105°C Endurance — Rated for operation up to 105°C with a specified load life of 5,000 hours at 105°C when applied with rated ripple current.
• High Ripple Current Capability — Specified ripple current: 18.2 A at 120 Hz (low frequency) and 25.48 A at 100 kHz (high frequency), supporting applications with substantial AC ripple demands.
• Screw Terminal Mounting — Radial can with screw terminals for robust, low-resistance connections and secure mechanical mounting in larger power assemblies.
• Series-Level Range — Part of the LNT family with an extended rated voltage range across the series (10 V to 500 V) and broad capacitance options, enabling selection within the same product family for design scalability.
• Operating Temperature and Polarization — Polarized capacitor rated for −25 °C to +105 °C operating range (for 160–500 V ratings) with ±20% capacitance tolerance at 120 Hz, 20 °C.
• RoHS Compliant — Complies with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• High-voltage energy storage — Use where large capacitance at several hundred volts is required for energy buffering or hold-up.
• Power filtering and smoothing — Suitable for smoothing DC bus voltages and reducing ripple in high-voltage power stages given its high ripple-current ratings.
• Industrial power assemblies — Screw-terminal package and robust temperature/lifetime specs make it suitable for larger power modules and assemblies requiring secure connections.

Unique Advantages

• Long high-temperature life: 5,000 hours at 105°C under rated ripple current supports reliable long-term operation in elevated-temperature environments.
• High ripple handling: Measured ripple currents of 18.2 A (120 Hz) and 25.48 A (100 kHz) help reduce heating and extend service life in ripple-intensive circuits.
• Screw-terminal reliability: Screw terminals provide low-resistance, vibration-resistant connections for heavy-current applications and easy installation or replacement.
• Series flexibility: The LNT series spans 10 V to 500 V and a wide capacitance range, enabling designers to standardize on a single family across multiple voltage classes.
• Wide operating range: Rated for −25 °C to +105 °C (for 160–500 V), allowing deployment in systems that operate across a broad temperature envelope.
• Regulatory readiness: RoHS compliance simplifies environmental-conformant product selection for regulated markets.
