Key Features

• Capacitance & Rated Voltage — 10000 µF nominal capacitance rated for 500 V DC.
• High Ripple Current — Rated ripple current: 38.3 A at 120 Hz and 53.62 A at 100 kHz to support heavy AC and high-frequency loading.
• Endurance & Lifetime — Load-life specification: 5000 hours at 85°C under rated ripple current; designed to meet endurance requirements after high-stress operation.
• Charge–Discharge Durability — Specified to withstand 50 million charge-discharge cycles (ΔV = rated × 0.3, 3 Hz) while meeting capacitance, tan δ, and leakage limits.
• Temperature Range — Operational from −40°C to +85°C, suitable for a wide range of industrial environments.
• Mounting & Package — Screw terminal radial can package for secure mechanical and electrical connections in power modules and assemblies.
• Smaller Size — Part of the LNC series designed to be smaller-sized while offering higher ripple current compared to earlier LNX/LNK series variants.
• Tolerance & Polarization — Capacitance tolerance ±20%; polarized electrolyte capacitor.
• Leakage & Insulation — Leakage current specified as not more than 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.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Power Supplies — Bulk and smoothing capacitor for inverter front-ends and high-power supply rails where high ripple currents are present.
• Motor Drive & Servo Systems — Energy buffering and regenerative voltage handling for AC servomotor drives and regenerative inverters.
• High-Frequency Power Modules — Applications requiring reliable operation at elevated frequencies, leveraging the 100 kHz ripple-current rating and high-speed charge-discharge capability.
• General Inverter Systems — DC-link and filtering in general-purpose inverters needing a robust, screw-terminal electrolytic solution.

Unique Advantages
