LNC2W472MSEGBB

The LNC2W472MSEGBB is a screw‑terminal, aluminum electrolytic capacitor offering 4.7 mF (4700 µF) at a 450 V rating in a compact radial can package. It is designed for industrial power conversion applications where high ripple handling, long operational life at elevated temperatures, and robust charge‑discharge endurance are required.

Typical use cases include industrial power supplies, inverter circuitry and high‑frequency regenerative voltage stages for AC servomotors and general inverter systems. The device combines high ripple current capability with a smaller physical footprint and RoHS compliance for easier integration into demanding power systems.

Key Features

• Capacitance & Voltage: 4.7 mF (4700 µF) nominal capacitance with a 450 V rated voltage suitable for high‑voltage power rails.
• Screw‑Terminal Package: Radial can with screw terminals for secure, low‑impedance connections in power assemblies and easy replacement or serviceability.
• High Ripple Current: Rated ripple current of 19.2 A at 120 Hz and 26.88 A at 100 kHz to support heavy AC loading and high‑speed charge/discharge cycles.
• Temperature Range & 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 Robustness: Designed to withstand high‑speed charge/discharge behavior and meets series endurance criteria including 50 million charge/discharge cycles at specified test conditions.
• Leakage Current & Insulation: Leakage current after 5 minutes is limited to 3√V (µA) or 5 mA, whichever is smaller (at 20 °C); insulation resistance is greater than 100 MΩ at DC 500 V between terminal and bracket, and the part withstands AC 2500 V for 1 minute between terminal and bracket.
• Polarized: Electrolytic, polarized construction for proper installation in DC power circuits.
• Tolerance: Capacitance tolerance ±20% (measured at 120 Hz, 20 °C).
• RoHS Compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing for high‑voltage rails in industrial converters and power modules.
• Inverter Circuits: DC link and energy buffering in general inverter designs where high ripple current handling is required.
• AC Servomotor Regeneration: High‑frequency regenerative voltage circuits for AC servomotors, supporting fast charge/discharge cycles and frequent energy recovery events.
• General Inverter Systems: Energy storage and decoupling in inverter topologies used across industrial automation and motion control.

Unique Advantages

• High ripple capacity: Clearly specified ripple currents at both low and high frequencies allow designers to size capacitors with confidence for heavy AC loads.
• Compact power density: Smaller‑sized radial can construction provides high capacitance in a reduced footprint for denser power assemblies.
• Proven high‑temperature life: 5000 hours rated life at 85 °C under rated ripple current helps ensure reliable operation in thermally demanding environments.
• Robust electrical integrity: Tight leakage current limits, high insulation resistance, and AC voltage proof testing reduce risk in high‑voltage installations.
• Durable for repetitive cycling: Endurance validated under extensive charge/discharge testing supports applications with frequent energy transfer and regenerative events.
• Regulatory compliance: RoHS conformance simplifies selection for designs requiring restricted‑substance compliance.
