LNT2V123MSEJBN

The LNT2V123MSEJBN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series designed for general-purpose power applications that require high capacitance at elevated voltages and temperatures. It delivers bulk energy storage and high ripple-current capability in a radial can with secure screw-terminal connections, and is rated for continuous operation up to +105°C.

Key Features

• Capacitance & Voltage — Rated capacitance of 12 mF at a nominal voltage of 350 V with a tolerance of -20% to +20%.
• High Ripple Current — Supports 36 A ripple at 120 Hz and 50.4 A at 100 kHz, suitable for high-current DC bus filtering and smoothing.
• Temperature & Endurance — Operating temperature range of -25 °C to +105 °C and a specified load life of 5,000 hours at +105 °C under rated ripple conditions.
• Mounting & Package — Radial can with screw terminals for robust electrical and mechanical connection; package described as Radial, Can - Screw Terminals.
• Polarized Design — Polar capacitor intended for DC applications.
• Physical Size — Compact form with overall dimensions L: 19 × D: 9 cm.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power systems — Bulk energy storage and DC bus smoothing where a 350 V rating and high capacitance are needed.
• Industrial power electronics — High ripple capability and +105 °C endurance support demanding thermal and ripple conditions in industrial equipment.
• Power supply filtering — Large capacitance plus high ripple current ratings help reduce voltage ripple in high-voltage supplies.

Unique Advantages

• High ripple-current capability: Rated ripple currents of 36 A (120 Hz) and 50.4 A (100 kHz) reduce heating and improve performance in high-current filter applications.
• High-voltage bulk capacitance: 12 mF at 350 V provides substantial energy storage for DC link and smoothing functions without multiple parallel components.
• Extended high-temperature life: Specified 5,000-hour load life at +105 °C under rated ripple current supports long-term reliability in elevated-temperature environments.
• Secure screw-terminal mounting: Robust mechanical and electrical connections simplify assembly and improve durability in vibration-prone installations.
• Regulatory compliance: RoHS compliance supports environmentally constrained designs.
