LNC2G182MTEF

The LNC2G182MTEF is an aluminum electrolytic, screw-terminal capacitor designed for industrial power electronics. It provides 1.8 mF capacitance at a 400 V rating in a stud-bolt mount package optimized for high ripple environments.

Engineered for inverter and regenerative applications, this capacitor delivers high ripple-current capability and extended load life (5,000 hours at 85°C), making it suitable for industrial power supplies, AC servomotor drives and other high-frequency charge/discharge systems.

Key Features

• Electrical Performance — 1.8 mF capacitance at 400 V nominal with a capacitance tolerance of -20% to +20% (measured at 20°C, 120 Hz).
• High Ripple Current — Designed for demanding ripple conditions: 12 A at 120 Hz (low frequency) and 16.8 A at 100 kHz (high frequency), supporting fast charge/discharge and switching loads.
• Loss Characteristics — Tangent of loss angle (tan δ) = 0.2 measured at 20°C, 120 Hz, supporting predictable AC performance.
• Mechanical & Mounting — Screw terminal radial can with stud bolt mount; package dimensions φ51 × 85 mm provide a compact footprint for high-energy applications.
• Reliability & Lifetime — Rated load life of 5,000 hours at 85°C under ripple current conditions; meets endurance and charge–discharge endurance criteria from the datasheet.
• Operating Range & Polarity — Polarized capacitor specified for operation from -40°C to +85°C.
• Leakage Current — Specified leakage current of 2,540 µA after voltage application (per product data).
• RoHS Compliant — Meets applicable RoHS directive requirements as noted in the product documentation.

Typical Applications

• Industrial Power Supplies — DC link and smoothing in inverter power supplies where sustained ripple current handling and reliable endurances are required.
• Motor Drives & Servo Systems — Energy buffering and high-frequency regenerative voltage support for AC servomotor controllers and general inverter systems.
• High-Frequency Switching Circuits — Supports rapid charge/discharge cycles and high-frequency switching environments with specified high-frequency ripple current capability.
• Regenerative Braking Circuits — Handles high-frequency regenerative voltages and associated ripple currents in energy-recovery systems.

Unique Advantages

• High ripple-current tolerance: Specified 12 A (120 Hz) and 16.8 A (100 kHz) ratings reduce thermal stress and support aggressive switching topologies.
• Long operational life under load: 5,000-hour rated life at 85°C under ripple conditions provides predictable maintenance intervals for industrial systems.
• Compact stud-mount package: φ51 × 85 mm dimensions and stud bolt mounting enable secure installation with a smaller footprint for power-dense assemblies.
• Engineered for high-speed charge/discharge: Low tan δ (0.2 at 20°C, 120 Hz) and construction suited to repetitive charge/discharge cycles support high-speed operation.
• RoHS compliant: Meets RoHS requirements for environmental compliance and regulatory alignment in commercial deployments.
