LNC2G332MSEG

The LNC2G332MSEG is an aluminum electrolytic capacitor in a screw-terminal, radial can package designed for industrial power applications. It provides 3300 µF capacitance at a 400 V rating, optimized for inverter circuitry, high-frequency regenerative voltage and high-speed charge–discharge loading.

Built for demanding industrial environments, the part delivers high ripple-current capability and a rated load life of 5000 hours at 85°C, while meeting RoHS (2011/65/EU, (EU)2015/863) requirements.

Key Features

• Electrical Capacity — 3300 µF nominal capacitance with a rated voltage of 400 V; capacitance tolerance is ±20% (–20% to +20%).
• High Ripple-Current Performance — Rated ripple current of 14.9 A at 120 Hz and 20.86 A at 100 kHz, supporting high-frequency inverter and regenerative circuits.
• Screw Terminal Mounting — Robust screw-terminal radial can package designed for secure, low-inductance connections in power assemblies.
• Temperature & Lifetime — Operational temperature range –40°C to +85°C with a rated load life of 5000 hours at 85°C when ripple current is applied.
• Reliable Endurance Characteristics — After the specified endurance test (D.C. bias plus rated ripple at 85°C for 5000 hours), capacitance change remains within ±20%, tan δ remains ≤200% of initial spec, and leakage current remains at or below initial values.
• Leakage and Insulation — Leakage current specification after 5 minutes follows the datasheet formula (not more than 3√V μA or 5 mA, whichever is smaller); insulation resistance between terminal and bracket exceeds 100 MΩ at DC 500 V.
• Safety Verification — Voltage-proof performance: no abnormality under AC 2500 V applied for 1 minute between terminal and bracket as per datasheet checks.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies / Inverter Circuits — Provides bulk energy storage and ripple filtering for inverter front-ends and industrial DC bus systems.
• AC Servomotor Regenerative Circuits — Handles high-frequency regenerative voltages and supports rapid charge–discharge cycles in servo drives.
• General Inverter Systems — Suited for power conditioning and DC link duties where high ripple current and long endurance are required.
• High-Speed Charge–Discharge Applications — Designed to cope with frequent, fast charge–discharge loading typical of industrial motor drives and power conversion equipment.

Unique Advantages

• High Ripple Capacity: Measured ripple current ratings (14.9 A at 120 Hz, 20.86 A at 100 kHz) enable stable operation under heavy AC ripple and high-frequency switching environments.
• Long Rated Life at Elevated Temperature: 5000 hours life at 85°C under rated ripple conditions provides predictable lifetime behavior for industrial systems.
• Secure Screw-Terminal Installation: Screw terminals deliver reliable electrical and mechanical connections for high-current power assemblies.
• Verified Insulation and Voltage Withstand: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V/1 min voltage-proof testing support safe integration into power modules.
• Smaller-Sized LNC Series Design: The LNC family delivers a smaller footprint with higher ripple capability compared to related series, helping reduce board and cabinet space in power equipment.
• Regulatory Compliance: RoHS compliance ensures material conformance for global industrial deployments.
