Key Features

• Capacitance & Voltage — 6.8 mF nominal capacitance rated for 400 V operation with ±20% tolerance at 120 Hz, 20°C.
• Screw-Terminal Mounting — Radial can package with screw terminals for secure, high-current connections in power assemblies.
• High Ripple-Current Capability — Handles 23.1 A at 120 Hz and 32.34 A at 100 kHz, supporting heavy AC and high-frequency regenerative loads.
• Temperature & Lifetime — Operational range −40°C to +85°C with a rated load life of 5000 hours at 85°C under applied ripple current.
• Charge–Discharge Endurance — Specified to meet performance requirements after 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz), demonstrating robustness for rapid switching applications.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to not more than 3√V (µA) or 5 mA, whichever is smaller (at 20°C).
• Insulation & Voltage Proof — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute with no abnormality.
• Polarized Construction — Electrolytic, polarized device for DC link and energy storage use in power electronics.
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).
• Compact Radial Can — Smaller-sized design in the LNC series while maintaining higher ripple capability compared to related LNX/LNK types.

Typical Applications

• Industrial Inverters — Used as DC-link and smoothing capacitors in inverter power supplies to support motor drive stability and energy buffering.
• Regenerative Servo Drives — Suited for high-frequency regenerative voltage handling in AC servomotor systems where frequent charge–discharge cycles occur.
• High-Frequency Power Supplies — Applicable where elevated ripple currents and rapid charge/discharge performance are required at both low and high frequencies.
