LNX2G122MSEF

The LNX2G122MSEF is an aluminum electrolytic, screw-terminal capacitor from Nichicon's LNX series designed for industrial power applications. It delivers high ripple-current capability and extra-high voltage performance in a large-can, radial package suited for demanding inverter and power-supply environments.

Engineered for reliability and long life, this polarized capacitor is rated for operation from −25°C to +85°C with endurance specified for 20,000 hours at +85°C under rated ripple current, making it appropriate where sustained high-ripple performance and longevity are required.

Key Features

• Capacitance & Voltage — Rated capacitance of 1.2 mF and a rated voltage of 400 V for high-voltage DC bus and energy-smoothing applications.
• High Ripple Current — Specified ripple current: 4.5 A at 120 Hz (low frequency) and 6.3 A at 100 kHz (high frequency), supporting heavy ripple environments.
• Long-Life Endurance — Endurance specified at 20,000 hours at +85°C when subjected to rated ripple current, supporting extended maintenance intervals.
• Operating Temperature — Rated for −25°C to +85°C to cover typical industrial ambient ranges.
• Robust Screw-Terminal Package — Radial can with screw terminals for secure, low-impedance connections in high-current layouts.
• Physical Dimensions — Body dimensions L: 8.0 cm × D: 5.1 cm with a seated height up to 3.15 inch for large-can mounting considerations.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20%; polarized design for DC applications.
• Safety & Compliance — Flame-retardant electrolyte option available and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy smoothing and DC bus stabilization in industrial supplies where high ripple and long life are required.
• Inverter Circuitry — DC link and filter capacitors for inverter systems that demand high ripple-current handling at elevated voltages.
• High-Voltage Power Conversion — Energy storage and decoupling in converters and choppers operating near the 400 V range.
• High-Ripple Environments — Systems that subject capacitors to continuous ripple stress benefit from the LNX2G122MSEF's rated ripple and endurance specifications.

Unique Advantages

• High ripple capability: Supports significant AC current stress (4.5 A @120 Hz; 6.3 A @100 kHz), reducing heating and performance degradation under ripple-loaded conditions.
• Long operational life at elevated temperature: Designed for 20,000 hours at +85°C under rated ripple current, lowering replacement frequency in continuous-duty equipment.
• Screw-terminal robustness: Provides secure, low-resistance connections ideal for high-current, serviceable power assemblies.
• Extra-high voltage readiness: 400 V rating accommodates high-voltage DC buses and converter topologies without compromising capacitance.
• Compliance and safety options: RoHS compliance and availability of flame-retardant electrolyte variants support regulatory and safety considerations.
