• Rated Voltage: 400 V DC rating suitable for medium-voltage inverter and power-supply rails.
• Screw Terminal Mounting: Radial can with screw terminals for secure, low-impedance connections in industrial assemblies.
• High Ripple Current Capability: 48.2 A at 120 Hz and 67.48 A at 100 kHz, supporting both low- and high-frequency switching environments.
• Wide Operating Temperature: Specified for –40 °C to +85 °C operation to cover typical industrial ambient ranges.
• Long Load Life: Endurance of 5,000 hours at 85 °C under rated ripple-current application, delivering predictable lifetime performance.
• Compact Footprint: Smaller-sized design within the LNC series while providing higher ripple current than comparable LNX and LNK series parts.
• Tolerance and Polarization: ±20% capacitance tolerance; polarized electrolyte construction for DC applications.
• Robust Endurance Characteristics: Meets series-level endurance tests including 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) with capacitance and tan δ limits maintained.
• Electrical Integrity: Leakage current specified after 5 minutes as not more than 3√V (µA) or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V dielectric proof for 1 minute with no abnormality.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters and Motor Drives: DC bus smoothing and energy buffering for inverter circuits used with AC servomotors and general drive systems.
• Regenerative Power Systems: Handling high-frequency regenerative voltages and rapid charge–discharge cycles in braking and energy-recovery circuits.
• Power Supply Bulk Storage: Bulk energy storage and ripple suppression in industrial power supplies that demand high ripple current capability and durable life.
• High-Speed Switching Circuits: Suited for applications requiring rapid charge–discharge handling and stable performance under high-frequency stress.

Unique Advantages

• High ripple-current handling: Rated ripple-current figures at 120 Hz and 100 kHz (48.2 A and 67.48 A) allow reliable operation in both low- and high-frequency switching topologies.
• Compact, high-power density: Smaller-sized LNC series construction delivers higher ripple tolerance than LNX and LNK series, saving board and chassis space while maintaining performance.
• Designed for long service life: 5,000-hour load-life specification at 85 °C under rated ripple current provides predictable longevity for industrial installations.
• Secure screw-terminal mounting: Screw terminals and radial-can packaging enable robust mechanical and electrical connections in rugged environments.
• Proven endurance under cycling: Meets series endurance tests including extensive charge–discharge cycling, ensuring stability for high-duty applications.
• Regulatory compliance: RoHS compliance supports use in assemblies requiring restricted-substance conformity.
