LNC2G123MSEJBN

The LNC2G123MSEJBN is an aluminum electrolytic, screw‑terminal capacitor from Nichicon’s LNC series designed for industrial power systems. It delivers 12 mF capacitance at 400 V in a radial can with screw terminals for secure mechanical and electrical connection.

Engineered for inverter circuitry and high‑frequency regenerative applications such as AC servomotors and general inverters, this part provides high ripple current capability, a long 5000‑hour load life at 85°C, and RoHS compliance.

Key Features

• Capacitance & Voltage — 12 mF nominal capacitance rated at 400 V DC with ±20% tolerance.
• Screw Terminal Mounting — Radial can package with screw terminals for robust mounting and reliable high‑current connections.
• High Ripple Current — Rated ripple current: 37.1 A at 120 Hz and 51.94 A at 100 kHz, supporting demanding AC and switching environments.
• Operating Temperature & Lifetime — Specified for −40 °C to +85 °C with a load‑life rating of 5000 hours at 85 °C under rated ripple conditions.
• Charge‑Discharge Endurance — Endurance for charge‑discharge behavior specified: 50 million cycles (ΔV = rated voltage × 0.3, 3 Hz) at room temperature.
• Leakage & Insulation — Leakage current after 5 minutes: not more than 3√V (μA) or 5 mA (whichever is smaller) at 20 °C; insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• Physical Dimensions — Compact radial can: L: 14.5 × D: 9 cm; seated height (max) 5.709 in, suitable where space and high performance must be balanced.
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Energy buffering and high‑frequency smoothing in inverter power stages to support stable DC link performance.
• AC Servomotor Drives — Handling regenerative voltage and high‑speed charge/discharge cycles in servo and motion‑control systems.
• Power Supplies for Motor Control — Bulk and ripple filtering in industrial power supplies where high ripple current and long life are required.

Unique Advantages

• High ripple handling: Explicit ripple ratings at 120 Hz and 100 kHz enable use in both low‑ and high‑frequency switching applications.
• Long operational life: 5000 hours of rated load life at 85 °C reduces maintenance frequency in industrial deployments.
• Robust mechanical termination: Screw‑terminal design provides secure, low‑impedance connections for high‑current systems.
• Charge/discharge resilience: Qualified for 50 million charge/discharge cycles at specified test conditions, supporting frequent regenerative events.
• Low‑temperature stability: Impedance stability down to −40 °C (Z(−40 °C)/Z(+20 °C) ≤ 8) for reliable performance across a wide ambient range.
• Regulatory readiness: RoHS compliance simplifies environmental and regulatory acceptance for industrial equipment.
