LNC2G103MTEJ

The LNC2G103MTEJ is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNC series, offering 10,000 µF at a 400 V rating with ±20% tolerance. Engineered for industrial power electronics, it is optimized for inverter circuitry and high-frequency regenerative voltage environments where high ripple handling and robust charge/discharge endurance are required.

With a specified operational range of −40°C to +85°C, a 5,000-hour load life at 85°C, and a compact φ90×120L package (L: 12 × D: 9 cm), this stud-mount, radial can capacitor provides a balance of energy storage, high ripple capability, and mechanical mounting convenience for demanding industrial applications.

Key Features

• High Capacitance and Voltage: 10,000 µF nominal capacitance at a 400 V rated voltage supports bulk energy storage and DC link applications.
• Screw Terminal / Stud Bolt Mount: Radial can with screw terminals and stud bolt mounting for secure, low-inductance connections in industrial assemblies.
• High Ripple Current Capability: Rated ripple current of 33.2 A at 120 Hz and 46.48 A at 100 kHz, enabling sustained operation under heavy AC ripple and high-frequency switching loads.
• Long Operational Life: Load life of 5,000 hours at 85°C when rated ripple current is applied, designed for continuous duty in power electronics systems.
• Robust Charge–Discharge Endurance: Specified endurance for charge–discharge behavior including qualification after repeated cycles (datasheet indicates endurance testing for 50 million cycles under defined conditions).
• Leakage and Dissipation: Leakage current specified up to 5,000 µA and tangent of loss angle (tan δ) 0.2, enabling predictable loss and self-discharge characteristics for design margining.
• Mechanical and Dielectric Integrity: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket, and voltage proof of AC 2500 V for 1 minute between terminal and bracket.
• Temperature Range and Packaging: Rated for −40°C to +85°C operation and supplied in cardboard packing; package dimensions φ90×120L (L: 12 × D: 9 cm) suit high-energy-density placements.
• RoHS Compliant: Meets RoHS directive (2011/65/EU, (EU)2015/863) for environmental compliance.

Typical Applications

• Industrial Inverters: Bulk DC-link and smoothing capacitor for inverter circuitry in industrial power supplies where sustained ripple and high-frequency performance are required.
• AC Servomotor Drives: Energy recovery and regenerative voltage buffering in servomotor and motion-control systems.
• High-Frequency Power Electronics: Applications requiring high ripple current handling at both low and high switching frequencies, including PWM and switching-regenerative topologies.

Unique Advantages

• High Energy Density at 400 V: 10,000 µF in a compact φ90×120L package provides substantial bulk capacitance for DC link and energy buffering without excessive board area.
• Designed for Heavy Ripple Loads: Rated ripple currents at 120 Hz and 100 kHz allow designers to size the capacitor confidently for both mains-frequency and switching-frequency stress.
• Durability for Continuous Operation: 5,000-hour life at 85°C under rated ripple conditions supports long-term uptime in industrial installations.
• Mechanical Reliability: Screw terminal / stud bolt mounting simplifies secure conductor attachment and supports robust field assembly and maintenance.
• Predictable Electrical Behavior: Specified tan δ and leakage current figures enable precise thermal and discharge budgeting in system designs.
• Compliance and Safety Margins: Insulation resistance and AC voltage proof data provide measurable safety margins between terminals and bracket for system-level dielectric considerations.
