LNC2W102MSEFBB

The LNC2W102MSEFBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNC series, offering a 1 mF capacitance at a 450 V rating. It is a radial, can-style, polarized capacitor engineered for industrial power applications that require high ripple handling and robust charge–discharge endurance.

Designed for inverter circuitry and high-frequency regenerative voltage environments such as AC servomotors and general inverters, this part delivers a compact package, high ripple current capability, and a 5000-hour load life at 85°C.

Key Features

• Rated Capacitance & Voltage — 1 mF capacitance at 450 V DC provides bulk energy storage for power conversion and regenerative circuits.
• Screw-Terminal Mounting — Radial can with screw terminals simplifies secure, high-current connections in industrial power assemblies.
• High Ripple Current — Supports 9.3 A at 120 Hz and 13.02 A at 100 kHz, enabling effective smoothing in high-frequency and high-current environments.
• Wide Operating Temperature — Rated for –40°C to +85°C to match industrial ambient conditions.
• Load Life — Endurance rated at 5000 hours with applied ripple current at 85°C, maintaining capacitance, tan δ, and leakage within specified limits after the test.
• Polarized, ±20% Tolerance — Polarized design with capacitance tolerance of −20% to +20% at 120 Hz, 20°C for predictable bulk capacitance in design margins.
• Robust Electrical Safety Characteristics — Insulation resistance >100 MΩ (DC 500 V between terminal and bracket) and voltage proof of AC 2500 V for 1 minute between terminal and bracket.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√V μA or 5 mA, whichever is smaller (at 20°C).
• Charge–Discharge Endurance — Qualified for repetitive charge–discharge behavior (50 million cycles at ΔV = rated voltage × 0.3, 3 Hz) while meeting capacitance, tan δ, and leakage requirements.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Physical dimensions L: 7.0 cm × D: 5.1 cm provide a smaller-sized option within the LNC family for space-constrained power modules.

Typical Applications

• Industrial Inverters — Bulk energy storage and ripple smoothing in inverter power supplies for motor drives and industrial automation.
• AC Servomotor Regeneration — Handles high-frequency regenerative voltages and rapid charge–discharge cycles common in servo drives.
• High-Frequency Power Supplies — Suitable for switch-mode and high-frequency regenerative circuits where elevated ripple current capacity is required.

Unique Advantages

• High Ripple Capability: Rated ripple currents at both low and high frequencies reduce thermal stress and improve reliability in high-current designs.
• Proven Endurance: 5000-hour load life at 85°C and qualification for 50 million charge–discharge cycles preserve performance over extended operating periods.
• Industrial-Grade Temperature Range: –40°C to +85°C operation supports deployment in demanding industrial environments.
• Secure Mechanical Termination: Screw terminals enable robust connections for high-current assemblies and easier field wiring or maintenance.
• Safety and Insulation Measures: High insulation resistance and AC voltage-withstand ratings between terminal and bracket support safe integration into power systems.
• RoHS Compliance: Meets environmental regulatory requirements for restricted substances.
