LNC2G392MTEG

The LNC2G392MTEG is a 3.9 mF (3900 µF) polarized aluminum electrolytic capacitor in a screw‑terminal, stud bolt mount can designed for power electronics. It delivers high ripple handling and long life in a compact form factor for industrial power supplies and inverter/regenerative applications.

Manufactured by Nichicon as part of the LNC series, this capacitor is optimized for high ripple currents and frequent charge‑discharge cycles while operating across a wide temperature range.

Key Features

• Capacitance & Voltage: 3.9 mF (3900 µF) nominal capacitance with a rated voltage of 400 V and ±20% tolerance, suitable for DC link and energy storage in power systems.
• High Ripple Current: Low‑frequency ripple current 16.5 A (120 Hz) and high‑frequency ripple current 23.1 A (100 kHz), enabling robust handling of AC and high‑speed switching loads.
• Long Endurance: Rated lifetime of 5000 hours at 85°C under rated ripple conditions, providing stable performance for extended operational periods.
• Thermal & Environmental Range: Operating temperature −40°C to +85°C and RoHS compliant construction.
• Low Loss & Leakage: Tangent of loss angle (tanδ) 0.2 measured at 20°C, 120 Hz, with a specified leakage current of 3740 µA.
• Mechanical & Mounting: Screw terminal can with stud bolt mount (radial, can – screw terminals), size φ63.5 × 100 mm (L: 10 cm × D: 6.35 cm), designed for secure installation in industrial enclosures.

Typical Applications

• Industrial Power Supplies: DC link and smoothing in inverter and converter power stages where high ripple current capability and endurance are required.
• AC Servo Drives & Inverters: Handling regenerative voltages and rapid charge/discharge cycles in motor control and drive systems.
• High‑Frequency Switching Systems: Support for high‑speed switching topologies thanks to elevated high‑frequency ripple current rating.

Unique Advantages

• High ripple capacity: 16.5 A at 120 Hz and 23.1 A at 100 kHz enables reliable suppression of AC ripple in both low and high frequency domains.
• Designed for heavy charge/discharge loading: Series specification notes suitability for high‑speed charge/discharge cycles and regenerative voltage, aligning with inverter and servo drive demands.
• Extended life at high temperature: 5000‑hour endurance at 85°C under rated ripple current provides predictable long‑term performance in demanding environments.
• Compact can format with stud mounting: Screw terminal can (φ63.5 × 100 mm) and stud bolt mount offer secure mechanical installation for industrial assemblies.
• Measured electrical stability: tanδ 0.2 at 20°C, 120 Hz and specified leakage current support predictable loss and insulation behavior in designs.
• Regulatory compliance: RoHS compliant for systems requiring restricted substances conformity.
