The LNC2W182MSEF from Nichicon is an aluminum electrolytic capacitor in the LNC series, designed with screw terminals for secure high-current connections. It provides 1800 µF capacitance at a 450 V rated voltage and is optimized for power electronics requiring high ripple tolerance and compact packaging.

Engineered for industrial power supplies, inverter circuitry and high-frequency regenerative voltage applications, this capacitor combines elevated ripple-current capability with a 5000-hour load life at 85°C, making it suitable for demanding charge–discharge and inverter environments.

Key Features

• Capacitance & Voltage — 1800 µF (1.8 mF) rated at 450 V for energy storage and DC bus smoothing in high-voltage power applications.
• High Ripple Current Handling — Rated ripple current of 11.5 A at 120 Hz and 16.1 A at 100 kHz to support high-frequency inverter and regenerative circuits.
• Load Life — 5000 hours at 85°C under rated ripple conditions, per series endurance specifications.
• Thermal Range — Operates from −40°C to +85°C, with specified impedance stability (Z(−40°C)/Z(+20°C) ≤ 8).
• Screw Terminal Package — Radial can with screw terminals for robust, low-resistance connections in high-current assemblies.
• Leakage & Loss Characteristics — Specified leakage current (2.7 mA) and tan δ 0.2 to support predictable performance and sizing in designs.
• Reliability Tests — Designed to meet endurance and charge–discharge life requirements (including 50 million charge–discharge cycles at ΔV = rated voltage × 0.3, 3 Hz, at room temperature) and insulation resistance/voltage-proof criteria.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.
• Compact Footprint — Smaller-sized design within the LNC series while delivering higher ripple current capability compared with prior LNX/LNK series.

Typical Applications

• Industrial Inverters — DC bus smoothing and energy buffering for inverter power stages where high ripple currents and long life are required.
• AC Servomotor Regeneration — Handling high-frequency regenerative voltages and rapid charge–discharge cycles in motor drive systems.
• Power Supplies — Bulk energy storage and ripple suppression in industrial power supplies and converters.
• High-Frequency Charge–Discharge Systems — Applications requiring repeated fast charge–discharge behavior, supported by the capacitor’s specified cycle endurance.
