LNC2W472MSEHBB

The LNC2W472MSEHBB is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNC series, providing 4700 µF capacitance at a 450 V rating. It is a smaller-sized, high-ripple-current radial can designed for demanding industrial power circuits.

This part is targeted at inverter and regenerative power electronics such as industrial power supplies and AC servomotor drives, offering high-frequency charge–discharge capability and a load life specified at elevated temperature.

Key Features

• Electrical rating: 4700 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, polarized for DC bus applications.
• High ripple-current capability: Supports 19.2 A at 120 Hz and 26.88 A at 100 kHz, enabling continuous ripple handling for inverter/regenerative circuits.
• Endurance and lifecycle: Load life of 5000 hours at 85°C with DC bias plus rated ripple current; designed to meet capacitance, tan δ and leakage limits after endurance testing.
• High-speed charge–discharge performance: Engineered to cope with rapid charge–discharge cycles and high-frequency regenerative voltages commonly seen in servo and inverter applications.
• Mechanical and mounting: Screw terminal radial can package for secure bus connections; physical size L: 11.5 cm × D: 7.62 cm and seated height up to 4.528 in for chassis planning.
• Thermal and environmental: Rated for operation from −40°C to +85°C and compliant with RoHS (2011/65/EU, (EU)2015/863).
• Leakage and insulation: Leakage current after 5 minutes is ≤ 3√V (µA) or 5 mA, whichever is smaller; insulation resistance ≥ 100 MΩ at DC 500 V between terminal and bracket.
• Robust charge–discharge endurance: Meets specified characteristics after 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz), supporting long-term cycling in regenerative systems.

Typical Applications

• Industrial inverters: Bulk DC bus energy storage and ripple smoothing in general inverter power stages where high ripple current and long load life are required.
• AC servomotor drives: Handling high-frequency regenerative voltages and rapid charge–discharge demands in servo drive regenerative circuits.
• Power supplies for industrial equipment: Filtering and energy buffering in industrial power supplies subject to continuous ripple and elevated ambient temperatures.

Unique Advantages

• High ripple current capability: Measured ripple specifications at both 120 Hz and 100 kHz support designs that must withstand continuous AC ripple and high-frequency switching stress.
• Compact, screw-terminal form factor: Radial can with screw terminals provides a secure electrical and mechanical connection while reducing board and chassis integration complexity.
• Long rated life at elevated temperature: 5000 hours at 85°C under rated ripple conditions gives predictable endurance for industrial applications.
• Proven charge–discharge durability: Specified endurance for 50 million cycles ensures suitability for systems with frequent regenerative events and rapid transitions.
• Strict leakage and insulation criteria: Leakage current and insulation resistance limits simplify design margining for safety and isolation requirements.
• RoHS compliant: Conforms to applicable RoHS directives for environmental and regulatory requirements.
