LNC2H472MSEJBN

The LNC2H472MSEJBN is a screw-terminal aluminum electrolytic capacitor designed for industrial power electronics. It provides 4.7 mF (4700 µF) capacitance at a 500 V rating in a radial can with screw terminals, optimized for inverter and regenerative power applications.

Engineered for high ripple environments, this capacitor delivers elevated ripple-current capability and long load life — specified for 5000 hours under ripple current at 85°C — and is RoHS compliant.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance rated at 500 V with ±20% tolerance.
• High Ripple Current — Rated ripple current of 23.6 A at 120 Hz and 33.04 A at 100 kHz to handle both low-frequency and high-frequency ripple loads.
• Temperature Range & Endurance — Operating range −40°C to +85°C with a load life of 5000 hours at 85°C when subjected to rated ripple current and DC bias.
• Screw Terminal Mounting — Radial can with screw terminals for secure, high-current connections and ease of installation.
• Compact, Robust Package — Package dimensions L: 10.5 × D: 9 cm with a maximum seated height of 4.134 inch, delivering a smaller-sized, higher-ripple alternative within the LNC series.
• Leakage Current Specification — After 5 minutes at 20°C, leakage current is not more than 3√(V) µA or 5 mA, whichever is smaller.
• Charge–Discharge Endurance — Designed to withstand high-speed charge–discharge: meets specified characteristics after 50 million charge–discharge cycles (ΔV = 0.3 × rated voltage, 3 Hz) at room temperature.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Energy storage and smoothing for power stages in inverter circuitry where high voltage and high ripple currents are present.
• AC Servomotor Drives — Support for high-frequency regenerative voltage and charge–discharge cycles in servo motor power systems.
• General Power Supplies — Bulk energy storage and ripple filtering in industrial power supplies and converters.
• High-speed Charge–Discharge Circuits — Applications requiring repeated, rapid charge/discharge behavior, validated by the product's charge–discharge endurance test.

Unique Advantages

• High ripple-current capability: Ripple ratings at both 120 Hz and 100 kHz enable reliable handling of varied switching and regenerative loads.
• Long operational life under load: 5000-hour load life at 85°C under ripple current provides predictable lifetime for industrial designs.
• Designed for dynamic duty: Proven endurance after 50 million charge–discharge cycles supports applications with frequent energy transfer events.
• Secure screw-terminal connection: Screw terminals simplify installation and ensure robust high-current wiring for power electronics assemblies.
• Regulatory compliance: RoHS conformity supports deployments where restricted substances compliance is required.
