LNC2W182MSEFBN

The LNC2W182MSEFBN is a screw-terminal aluminum electrolytic capacitor designed for industrial power electronics. It provides 1.8 mF (1800 µF) capacitance at a 450 V rating in a compact radial can with screw terminals, optimized for inverter and regenerative circuits.

Engineered for high ripple environments and repeated charge–discharge loading, this capacitor is suited to industrial power supplies, AC servomotor regenerative systems and general inverter applications where high-frequency ripple and endurance are required.

Key Features

• Capacitance and Voltage: 1.8 mF (1800 µF) nominal capacitance at 450 V rated voltage, with ±20% tolerance (measured at 120 Hz, 20°C).
• Screw Terminal Mounting: Radial can with screw terminals for secure, low-resistance connections in industrial assemblies.
• High Ripple Current Capability: Rated ripple current of 11.5 A at 120 Hz and 16.1 A at 100 kHz to support high-frequency loading and regenerative currents.
• Temperature and Lifetime: Operating temperature range –40°C to +85°C with a specified load life of 5000 hours when rated ripple current is applied at 85°C.
• Compact Footprint: Smaller-sized design compared to LNX and LNK series while maintaining higher ripple current handling (size L: 10.5 × D: 5.1 cm).
• Robust Endurance: Designed to cope with high-speed charge–discharge behavior; series-level test includes 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) with defined performance limits.
• Leakage and Insulation: Leakage current after 5 minutes is not more than 3√(V) µA or 5 mA, whichever is smaller; insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket.
• Voltage Withstand: Voltage proof tested at AC 2500 V for 1 minute between terminal and bracket.
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Used in inverter circuitry where high ripple current and long life at elevated temperatures are required.
• AC Servomotor Regenerative Circuits: Handles high-frequency regenerative voltages and fast charge–discharge loads common in servo drive systems.
• General Inverters: Provides bulk energy storage and ripple smoothing in inverter designs for industrial drives and power conversion equipment.

Unique Advantages

• High Ripple Endurance: Measurable ripple current ratings at both low and high frequencies (11.5 A @ 120 Hz, 16.1 A @ 100 kHz) reduce thermal stress and extend service life in ripple-intensive designs.
• Extended Operating Life at Elevated Temperature: 5000 hours load life at 85°C under rated ripple current provides predictable aging for industrial applications.
• Compact, High-Performance Form Factor: Smaller-sized than comparable series (LNX/LNK) while delivering higher ripple capability, enabling space-efficient power modules.
• Designed for Repetitive Charge–Discharge: Series-level endurance tests for 50 million charge–discharge cycles indicate suitability for high duty-cycle regenerative and pulse applications.
• Secure Mechanical and Electrical Connections: Screw-terminal mounting enables reliable installation and low contact resistance in rugged industrial assemblies.
• Measured Safety Margins: Defined leakage, insulation resistance and dielectric proof test criteria provide clear, verifiable electrical performance limits.
