LNC2W332MSEGBN

The LNC2W332MSEGBN is an aluminum electrolytic capacitor in a screw-terminal radial can package, designed for industrial power applications. It delivers 3300 μF at 450 V with a compact, smaller-sized footprint and is optimized for high ripple current and high-frequency regenerative voltages.

Targeted use cases include inverter power supplies and AC servomotor regenerative circuitry where sustained ripple handling and long operational life at elevated temperatures are required.

Key Features

• Capacitance & Voltage — 3300 μF rated capacitance at 450 V provides bulk energy storage for power electronics and inverter rails.
• Screw-Terminal Radial Can — Screw terminal mounting with a radial can package supports secure, low-inductance connections for high-current power paths.
• High Ripple Current Capability — Rated ripple current of 15.6 A at 120 Hz and 21.84 A at 100 kHz to support high-frequency switching and regenerative loads.
• Smaller Size for Power Density — Smaller-sized construction compared with LNX and LNK series while maintaining higher ripple current handling, enabling denser power module designs (physical size: L 11.5 × D 6.35 cm).
• Wide Operating Temperature — Rated for −40 °C to +85 °C operation to suit industrial ambient conditions.
• Endurance and Life — Load-life specification: 5000 hours with DC bias plus rated ripple current at 85 °C; designed to retain capacitance and leakage characteristics after endurance testing.
• Charge–Discharge Durability — Specified endurance under repeated charge–discharge cycles (50 million cycles at ΔV = 0.3 × rated voltage, 3 Hz), demonstrating robustness for rapid energy transfer applications.
• Leakage, Insulation and Voltage Proof — Leakage current limited to not more than 3√(V) μA or 5 mA after 5 minutes (20 °C); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V one-minute voltage proof between terminal and bracket.
• Polarized with ±20% Tolerance — Polarized capacitor with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• RoHS Compliant — Manufactured in compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk energy smoothing and ripple handling on DC bus lines in general inverter power supplies, leveraging high ripple current capability.
• AC Servomotor Drives — Support for high-frequency regenerative voltage and rapid charge–discharge cycles common in servo drive regenerative braking and torque control.
• Power Supply Modules — Energy storage and ripple absorption in industrial power supplies where long load life at elevated temperature is required.

Unique Advantages

• Higher Ripple Capacity at Small Size: Delivers elevated ripple current (15.6 A @120 Hz; 21.84 A @100 kHz) in a smaller package compared with LNX/LNK series, enabling higher power density.
• Designed for High-Frequency Regeneration: Engineered to cope with high-speed charge–discharge and high-frequency regenerative voltages typical of motor drive systems.
• Long Operational Lifetime: 5000-hour load-life rating at 85 °C under rated ripple conditions provides predictable longevity for continuous industrial use.
• Robust Electrical Isolation: High insulation resistance and AC voltage-proof testing between terminal and bracket support reliable mounting and system safety checks.
• Durability Under Cycling: Qualification for 50 million charge–discharge cycles at defined ΔV and frequency indicates suitability for frequent switching environments.
• Industry-Ready Compliance: RoHS compliance supports use in regulated industrial equipment and assemblies.
