LNC2H182MTEG

The LNC2H182MTEG is a Nichicon LNC series aluminum electrolytic capacitor in a screw‑terminal, stud bolt mount configuration. It delivers 1.8 mF capacitance at a 500 V rating and is engineered for industrial power electronics where high ripple handling and reliable long‑term operation are required.

Designed for inverter circuitry and industrial power supplies, this capacitor is sized for compact installations while supporting high‑frequency regenerative voltages such as those found in AC servomotor and general inverter applications. Key value propositions include high ripple current capability, 5000‑hour endurance at 85°C, and RoHS compliance.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) nominal capacitance with a 500 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High ripple current capability — Rated low‑frequency ripple current of 12.7 A at 120 Hz and high‑frequency ripple current of 17.78 A at 100 kHz to support demanding power and regenerative loads.
• Stud bolt / screw‑terminal package — Stud bolt mount with screw terminals in a radial can package for secure, low‑impedance connections in power assemblies.
• Endurance and reliability — Load life specified as 5000 hours with D.C. bias plus rated ripple current at 85°C; designed for continual operation under rated conditions.
• Electrical characteristics — Loss tangent (tan δ) of 0.2 (measured at 20°C, 120 Hz) and measured leakage current of 2840 µA.
• Operating environment — Rated for use across a −40°C to +85°C temperature range.
• Size and packaging — Cylindrical case φ63.5 × 90L (approx. 9.0 × 6.35 cm) supplied in cardboard packing for shipment and handling.
• Regulatory compliance — Compliant with RoHS directive.

Typical Applications

• Industrial power supplies — Bulk and smoothing capacitor for inverter front ends and DC link sections in industrial power systems.
• Inverter circuitry — Supports high‑speed charge/discharge and regenerative voltage conditions in general inverter designs.
• AC servomotor drives — Handles high‑frequency regenerative currents typical in servomotor power stages.

Unique Advantages

• High ripple tolerance: Specified 12.7 A at 120 Hz and 17.78 A at 100 kHz, enabling use in high‑ripple, high‑frequency power circuits without overspecifying parallel capacitance.
• Long endurance at elevated temperature: 5000 hour life at 85°C under rated ripple conditions supports sustained performance in industrial environments.
• Stud bolt screw‑terminal design: Robust mechanical and electrical connection suitable for heavy current paths and secure mounting in power assemblies.
• Measured electrical stability: Tan δ of 0.2 (20°C, 120 Hz) and defined leakage current provide predictable loss and leakage behavior for design margins.
• RoHS compliant: Meets RoHS directive for use in regulatory‑conscious supply chains.
• Compact form factor for its class: φ63.5 × 90L package balances capacitance and voltage in a space‑efficient can for inverter and power applications.
