LNC2G332MSEGBN

The LNC2G332MSEGBN is a screw-terminal aluminum electrolytic capacitor designed for industrial power electronics. It delivers 3300 µF capacitance at 400 V in a radial can with screw terminals, engineered for inverter and regenerative circuits that require high ripple-current handling and compact packaging.

Built for continuous operation across –40°C to +85°C, this capacitor offers a 5000-hour load life at 85°C under applied ripple current, making it suitable for demanding industrial power-supply and motor-control environments.

Key Features

• Capacitance & Voltage — 3300 µF nominal capacitance at a rated voltage of 400 V with ±20% tolerance (120 Hz, 20°C).
• High ripple-current capability — Rated ripple current: 14.9 A at 120 Hz and 20.86 A at 100 kHz, supporting heavy AC and high-frequency regenerative loads.
• Temperature range & endurance — Operating range of –40°C to +85°C and load life of 5000 hours at 85°C with rated ripple current applied.
• Charge–discharge durability — Designed to withstand high-speed charge–discharge; specified endurance includes 50 million charge–discharge cycles (ΔV = 0.3 × rated voltage, 3 Hz).
• Leakage, insulation and voltage proof — Leakage current limited to 3√V (µA) or 5 mA (whichever is smaller) after 5 minutes at rated voltage; insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V, 1 minute voltage proof between terminal and bracket.
• Package & mounting — Radial, can-style package with screw terminals for secure electrical and mechanical connections; physical footprint approximately L: 9.0 cm × D: 6.35 cm.
• Compliance — RoHS compliant per the listed directives.

Typical Applications

• Industrial inverters — Energy storage and smoothing for inverter power stages in industrial drives and power supplies.
• Regenerative motor drives — Handles high-frequency regenerative voltage for AC servomotors and other motor-control systems.
• High-speed charge–discharge circuits — Suited for circuits that require rapid charging and discharging cycles in power electronics.
• General-purpose power supplies — Bulk filtering and decoupling in industrial power-supply designs where high ripple current and long life are required.

Unique Advantages

• High ripple-current handling: Explicit ripple ratings at both 120 Hz and 100 kHz (14.9 A and 20.86 A) support heavy AC and high-frequency loads.
• Compact, high-performance form factor: Described as smaller-sized with higher ripple current versus comparable series, enabling space-saving designs without sacrificing performance.
• Long operational life at elevated temperature: 5000-hour load life at 85°C under ripple conditions offers predictable longevity for industrial applications.
• Robust charge–discharge endurance: Specified ability to endure 50 million charge–discharge cycles supports applications with frequent energy cycling.
• Electrical reliability: Measured leakage, insulation resistance and voltage-proof specifications provide verifiable safety margins for power-system integration.
• Regulatory compliance: RoHS compliance aligns the component with environmental requirements for industrial equipment.
