LNX2V183MSEJBN

The LNX2V183MSEJBN is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage, high-ripple power applications. It delivers 18,000 µF capacitance at a 350 V rating and is part of Nichicon's LNX series engineered for long-life performance in industrial environments.

Typical uses include industrial power supplies and inverter circuitry where prolonged endurance, high ripple capability and secure screw-terminal connections are required. The part provides a balance of high capacitance, robust ripple handling and extended service life.

Key Features

• Capacitance & Voltage — 18,000 µF nominal capacitance at a rated voltage of 350 V with capacitance tolerance of ±20% (120 Hz, 20°C).
• Long Endurance — Rated for 20,000 hours at +85°C under standard ripple current conditions, supporting extended operational life in elevated-temperature installations.
• High Ripple Current Handling — Rated ripple current of 32.4 A at 120 Hz and 45.36 A at 100 kHz, suitable for demanding power-conversion ripple environments.
• Secure Screw-Terminal Package — Radial, can-type body with screw terminals for robust, low-resistance connections in high-current applications; nominal size φ90 × 220L (L: 22 cm × D: 9 cm).
• Operating Temperature — Specified for operation from −25°C to +85°C to match a wide range of industrial ambient conditions.
• Leakage Current Specification — Leakage current limited per datasheet: after 5 minutes at rated voltage, not more than 3√CV (µA) or 5 mA, whichever is smaller (at 20°C).
• Polarized, General-Purpose Design — Polarized electrolytic construction intended for general-purpose power applications.
• Environmental Compliance & Options — RoHS compliant; flame-retardant electrolyte option available for applicable types.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in industrial power supply designs where high voltage and ripple capability are required.
• Inverter Circuitry — Energy buffering and decoupling for inverter stages that demand high ripple current and long operational life at elevated temperatures.
• General-Purpose High-Voltage Power Systems — High-capacitance, high-voltage applications requiring durable, screw-terminal mounting and long endurance.

Unique Advantages

• Extended high-temperature life: 20,000-hour endurance at +85°C under rated ripple current reduces replacement frequency and maintenance in continuous-duty systems.
• Strong ripple performance: High ripple ratings (32.4 A @ 120 Hz; 45.36 A @ 100 kHz) support demanding switching and power-conversion loads.
• High-voltage capability: 350 V rating enables use in higher-voltage DC bus and power-conversion applications without additional series stacking.
• Robust electrical connections: Screw-terminal radial-can package provides secure, low-impedance terminations for high-current installations.
• Large bulk capacitance in a serviceable package: 18,000 µF in a φ90×220L can delivers substantial energy storage with straightforward mounting and wiring.
• Regulatory and safety-focused options: RoHS compliance and availability of flame-retardant electrolyte types help address environmental and safety considerations.
