LNC2W122MSEF

The LNC2W122MSEF is an aluminum electrolytic capacitor in a screw-terminal radial can designed for industrial power electronics. It provides 1200 µF capacitance at a 450 V rating and is built for high ripple current environments and frequent charge–discharge cycling.

Targeted at inverter circuitry and regenerative systems, this Nichicon LNC-series unit delivers a compact footprint, high ripple handling and a rated load life of 5000 hours at 85 °C under applied ripple current, making it suitable for demanding industrial power-supply applications.

Key Features

• Capacitance and Voltage: 1200 µF (1.2 mF) rated at 450 V for DC link and energy-buffering applications.
• Screw Terminal Package: Radial can with screw terminals for secure, high-current connections in power assemblies.
• High Ripple Current: Designed for high ripple environments with specified ripple currents of 9.9 A at 120 Hz and 13.86 A at 100 kHz.
• Thermal and Environmental Range: Operates from −40 °C to +85 °C and is RoHS compliant (2011/65/EU, (EU)2015/863).
• Longevity under Load: Endurance specified as 5000 hours at 85 °C with DC bias plus rated ripple current applied; capacitance change and leakage specified per datasheet limits.
• Charge–Discharge Endurance: Qualified for charge–discharge behavior testing (50 million cycles at ΔV = rated voltage × 0.3, 3 Hz) to meet durability requirements for frequent switching/regeneration.
• Electrical Safety Characteristics: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket, and voltage proof of AC 2500 V for 1 minute between terminal and bracket.
• Compact Footprint: Smaller-sized construction compared with earlier LNX and LNK series while maintaining higher ripple capability; physical footprint 8 cm × 5.1 cm (L × D).
• Leakage Current: Specified leakage current limit after 5 minutes: not more than 3√V µA or 5 mA, whichever is smaller (at 20 °C).

Typical Applications

• Industrial Inverter Power Supplies: DC-link smoothing and energy buffering in inverter circuitry for industrial drives.
• AC Servomotor Regeneration: Handling high-frequency regenerative voltages in AC servomotor applications where frequent charge–discharge occurs.
• General Motor Inverters: Energy storage and ripple suppression in general inverter systems for industrial motor control.

Unique Advantages

• High ripple-current capability: Specified ripple ratings at both low and high frequencies help ensure stable operation in high-current AC/DC switching environments.
• Designed for frequent charge–discharge: Endurance testing to 50 million cycles supports applications with rapid energy transfer and regenerative events.
• Robust load-life specification: 5000 hours at 85 °C under rated ripple current provides predictable lifetime performance in elevated-temperature enclosures.
• Secure screw-terminal mounting: Screw terminals offer reliable electrical and mechanical connection for high-current bus implementations.
• Compact than legacy models: Smaller-sized design compared to LNX/LNK series allows tighter packaging in power assemblies while maintaining high ripple handling.
• Clear electrical safety margins: High insulation resistance and specified voltage-proof test provide measurable isolation performance between terminal and bracket.
