LNC2G123MSEJBB

The LNC2G123MSEJBB is a screw‑terminal aluminum electrolytic capacitor rated 12,000 µF at 400 V, designed for industrial power electronics. It is a smaller‑sized, high‑ripple current capacitor intended for inverter circuitry and high‑frequency regenerative voltage applications such as AC servomotor and general inverters.

Engineered for continuous ripple loading, the part offers a 5,000‑hour load life at 85°C and is optimized for high‑speed charge/discharge and high‑frequency operation while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 12,000 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance (120 Hz, 20°C), providing bulk energy storage for power conversion and energy recovery circuits.
• Screw‑Terminal Package — Radial can with screw terminals for secure, low‑impedance connections in industrial power assemblies and inverter stacks.
• High Ripple Current Capability — Rated ripple current of 37.1 A at 120 Hz and 51.94 A at 100 kHz to support heavy AC ripple and high‑frequency regenerative duty.
• Temperature Range & Reliability — Rated for –40°C to +85°C operation with a specified load life of 5,000 hours at 85°C under rated ripple current conditions.
• Charge‑Discharge Endurance — Verified for repeated charge/discharge stress (50 million cycles at ΔV = rated × 0.3, 3 Hz) with recovery to specified electrical limits.
• Leakage, Insulation & Withstand — Leakage current specified as not more than 3√V µA (or 5 mA, whichever is smaller) after 5 minutes at rated voltage; insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V, 1 minute voltage proof between terminal and bracket.
• Smaller Footprint vs. Comparable Series — Designed to be smaller in size while delivering higher ripple current than the LNX and LNK series, enabling denser power module layouts.
• RoHS Compliant — Manufactured in compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk energy storage and ripple filtering for inverter front ends and DC bus smoothing in industrial motor drives.
• AC Servomotor Regenerative Circuits — Handling high‑frequency regenerative voltages and frequent charge/discharge cycles in servo power systems.
• General Power Supplies — High‑ripple DC bus applications in industrial power supplies where high ripple current and long life at elevated temperature are required.

Unique Advantages

• High ripple‑handling capacity: Specified ripple currents at both low and high frequencies (37.1 A @120 Hz, 51.94 A @100 kHz) reduce thermal stress and support demanding regenerative loads.
• Long operational life under ripple: 5,000 hours load life at 85°C with rated ripple current provides predictable end‑of‑life characteristics for long‑running systems.
• Robust charge/discharge endurance: Qualified for 50 million charge/discharge cycles at room temperature, demonstrating suitability for frequent regenerative events.
• Secure mechanical termination: Screw‑terminal radial can construction enables reliable, low‑resistance connections in industrial assemblies.
• Compact design for power modules: Smaller than comparable LNX/LNK series parts while maintaining high ripple capability, enabling tighter power electronics layouts.
• Verified electrical integrity: Tight leakage and insulation specifications plus AC withstand testing support safe integration into high‑voltage DC bus environments.
