Key Features

• Capacitance & Voltage: 3.9 mF (3900 µF) rated at 350 V, suitable for bulk energy storage in power stages.
• Screw Terminal Mounting: Radial can with screw terminals for secure, high-current connections in industrial assemblies.
• High Ripple Current: 14.3 A at 120 Hz and 20.02 A at 100 kHz, enabling handling of heavy AC ripple in inverter and regenerative circuits.
• Temperature Range & Endurance: Specified for –40°C to +85°C with a load life of 5000 hours at 85°C under rated ripple conditions.
• Charge–Discharge Durability: Endurance specified after 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz), supporting high-speed switching environments.
• Electrical Robustness: Leakage current limit after 5 minutes is not more than 3√V (µA) or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V; voltage proof test AC 2500 V for 1 minute between terminal and bracket.
• Compact Footprint: Physical dimensions L: 7 cm × D: 7.62 cm, providing a smaller-sized option within the LNC series and cited as smaller-sized / higher ripple current than LNX and LNK series.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk and smoothing capacitance for inverter front-ends and switch-mode power supplies used in industrial systems.
• Inverter & Regenerative Circuits: Energy buffering and ripple handling for general inverters and regenerative voltage circuits.
