LNC2G122MSEFBN

The LNC2G122MSEFBN is an aluminum electrolytic capacitor in a screw-terminal, radial can package designed for industrial power applications. It pairs a 1.2 mF capacitance with a 400 V rating and is optimized for high ripple current and high-speed charge–discharge loading in inverter and regenerative circuits.

Engineered for sustained operation across –40 °C to +85 °C, this capacitor offers a rated load life of 5000 hours at 85 °C under ripple-current conditions, making it suitable for industrial power supplies, AC servomotor regenerative systems and general inverter applications.

Key Features

• Electrical Rating — 1.2 mF capacitance at 400 V DC with ±20% tolerance, providing bulk energy storage for power conversion and smoothing.
• High Ripple Current Capability — Rated ripple current of 9.3 A at 120 Hz and 13.02 A at 100 kHz to support high-frequency inverter and regenerative workloads.
• Load Life and Endurance — Endurance specification: 5000 hours at 85 °C with D.C. bias plus rated ripple current; capacitance change and loss angle stay within defined limits after this period.
• Charge–Discharge Durability — Designed to withstand 50 million charge–discharge cycles (ΔV = rated voltage × 0.3, 3 Hz) while meeting post-test electrical requirements.
• Mechanical & Mounting — Screw terminal, radial can package with dimensions L: 6.5 cm × D: 5.1 cm and a seated height specification for panel or bracket mounting.
• Thermal Range & Reliability — Operating range –40 °C to +85 °C with shelf-life and endurance tests ensuring stability after elevated-temperature storage and reconditioning.
• Insulation & Voltage Proof — Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket without abnormality.
• RoHS Compliance — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk smoothing and ripple handling in inverter power stages where high DC voltage and sustained ripple capability are required.
• Regenerative Drives / AC Servomotors — Supports high-frequency regenerative voltage and energy absorption during motor braking and recovery.
• High-Frequency Power Supplies — Suited for power supplies that require high ripple-current handling and rapid charge–discharge performance.
• General Power Conditioning — Energy storage and filtering in systems exposed to frequent current transients and fast switching events.

Unique Advantages

• High ripple-current performance: Ripple ratings of 9.3 A (120 Hz) and 13.02 A (100 kHz) help manage heat and extend system reliability in high-frequency power circuits.
• Long rated load life: 5000 hours at 85 °C under rated ripple current provides predictable aging and replacement planning for industrial equipment.
• Durable under repetitive cycling: Qualified for 50 million charge–discharge cycles, enabling use in applications with frequent transients and regenerative events.
• Robust insulation and voltage handling: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V voltage-proof verification reduce risk of terminal-to-bracket breakdown.
• Compact screw-terminal package: Smaller-sized, high-ripple design in a radial can with screw terminals simplifies mounting and integration into existing power assemblies.
• RoHS-compliant construction: Meets RoHS directive requirements for environmentally constrained designs.
