LNC2W182MSEGBN

The LNC2W182MSEGBN is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNC series, designed for high‑performance power electronics. It delivers 1.8 mF capacitance at 450 V in a compact radial can with screw terminals, targeting industrial power supplies and inverter circuitry.

Key value comes from its higher ripple‑current capability and long load life (5000 hours at 85°C), making it suitable for regenerative and high‑frequency charge/discharge environments such as AC servomotor drives and general inverters.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 μF) rated at 450 V with ±20% tolerance (120 Hz, 20°C).
• Screw‑Terminal Package — Radial can with screw terminals for secure, low‑inductance connections in power assemblies.
• High Ripple Current — Rated ripple performance of 11.9 A at 120 Hz and 16.66 A at 100 kHz to support demanding AC and high‑frequency loads.
• Thermal & Life Ratings — Operating range –40°C to +85°C with load life of 5000 hours at 85°C under rated ripple current.
• Electrical Robustness — Leakage current spec after 5 minutes not more than 3√V μA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute.
• Charge‑Discharge Endurance — Withstands 50 million charge‑discharge cycles (ΔV = 0.3 × rated voltage, 3 Hz) while meeting capacitance, tan δ, and leakage limits.
• Compact Footprint — Smaller‑sized, higher ripple current construction compared with LNX and LNK series; typical dimensions L: 7 cm × D: 6.35 cm, with seated height specification provided.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies for Inverters — Energy storage and smoothing in inverter front ends where high DC voltage and ripple handling are required.
• AC Servomotor Regenerative Circuits — Handles high‑frequency regenerative voltages and high speed charge/discharge cycles in motor drive systems.
• General Inverter and Motor Drive Systems — Bulk DC link and filtering for converters and drive electronics demanding long life and high ripple capability.
• High‑Frequency Charge/Discharge Applications — Applications that repeatedly cycle voltage where robust charge‑discharge endurance is necessary.

Unique Advantages

• Higher Ripple Capability: Measured ripple currents of 11.9 A (120 Hz) and 16.66 A (100 kHz) support heavy AC and HF loading without premature degradation.
• Long Operational Life: Designed for 5000 hours of loaded operation at 85°C, providing predictable performance for industrial power systems.
• Charge‑Discharge Durability: Qualified for 50 million charge/discharge cycles (ΔV = 0.3 × Vr) to maintain capacitance and leakage characteristics in cyclic applications.
• Robust Electrical Safety Margins: Insulation resistance >100 MΩ (DC 500 V) and AC 2500 V dielectric proof reduce risk of terminal‑to‑bracket failures.
• Compact, Serviceable Form Factor: Screw‑terminal radial can enables secure mounting and easy replacement in power racks and assemblies; smaller than comparable LNX/LNK series units.
• Regulatory Compliance: RoHS conformity simplifies integration into equipment targeting regulated markets.
