LNC2V123MSEJBN

The LNC2V123MSEJBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNC series, offering 12,000 µF capacitance at a 350 V rating. It is a radial, can-style capacitor designed for high-current, high-frequency industrial power applications where compact energy storage and reliable ripple handling are required.

Key value comes from its high ripple-current capability, a rated operating range of −40 °C to 85 °C, and a specified load life of 5000 hours at 85 °C, making it suitable for inverter circuitry, regenerative circuits, and other demanding power-electronic systems.

Key Features

• Capacitance & Voltage: 12,000 µF capacitance at a 350 V rated voltage, with a tolerance of ±20% (120 Hz, 20 °C).
• Screw-Terminal Mounting: Radial can with screw terminals for secure high-current connections and robust mechanical fixation.
• High Ripple-Current Performance: Rated ripple current of 30.1 A at 120 Hz and 42.14 A at 100 kHz, supporting high-frequency and high-current applications.
• Temperature and Lifetime: Operates from −40 °C to 85 °C with a specified load life of 5000 hours at 85 °C under rated ripple conditions.
• Endurance & Charge–Discharge Reliability: Designed to withstand high-speed charge–discharge cycles; specified endurance includes performance after 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) at room temperature.
• Electrical Integrity: Leakage current specification after 5 minutes is limited to not more than 3√(V) µA or 5 mA (whichever is smaller); insulation resistance > 100 MΩ at DC 500 V between terminal and bracket.
• Compact Physical Package: φ90×120L form factor (L: 12 × D: 9 cm) providing large capacitance in a reduced footprint for its class.
• RoHS Compliant: Meets RoHS directive requirements.

Typical Applications

• Industrial Inverters: Energy buffering and smoothing in inverter DC-link circuits for motor drives and power converters.
• Regenerative Servo Systems: Handling high-frequency regenerative voltages and rapid charge–discharge cycles in AC servomotor drives.
• High-Frequency Power Supplies: Bulk energy storage and ripple suppression in high-frequency switching power supplies and industrial power electronics.

Unique Advantages

• High ripple-current capability: Substantial ripple ratings at both low (120 Hz) and high (100 kHz) frequencies reduce temperature rise and extend service life under heavy AC loading.
• Long rated load life: 5000 hours at 85 °C under rated ripple conditions provides predictable end-of-life characteristics for long-running industrial equipment.
• Screw-terminal connections: Enables reliable, low-resistance high-current terminations suitable for power-electronics assemblies.
• Designed for rapid charge–discharge: Specified endurance for high-speed cycling supports applications with frequent energy transfer events.
• Clear electrical limits: Defined leakage-current and insulation-resistance criteria allow straightforward design margining and verification.
• Regulatory compliance: RoHS compliance facilitates use in global industrial products requiring restricted-substance adherence.
