LNC2H103MTEJ

The LNC2H103MTEJ is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNC series, specified at 10,000 µF and 500 V. It is a stud/bolt-mount radial can designed for industrial power electronics that demand high ripple capability and long operational life under elevated temperature.

Engineered for inverter and regenerative applications, this capacitor combines high ripple-current handling at both low and high frequencies with a 5,000-hour endurance at 85°C, making it suitable for demanding AC servomotor drives, general inverters, and industrial power supplies.

Key Features

• High Capacitance and Voltage: 10,000 µF rated capacitance at 500 V provides substantial energy storage for power conversion and smoothing tasks.
• High Ripple Current Capability: Rated ripple current of 38.3 A at 120 Hz and 53.62 A at 100 kHz supports heavy low-frequency and high-frequency ripple loads typical of inverter and regenerative circuits.
• Long Endurance at Elevated Temperature: 5,000 hours rated life at 85°C when subjected to DC bias plus rated ripple current, with post-endurance limits: capacitance change within ±20% and leakage and tan δ meeting specified limits.
• Robust Leakage and Reliability Characteristics: Specified leakage current of 5,000 µA and insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket (series specification), supporting predictable behavior in service.
• Operation over Wide Temperature Range: Rated for −40°C to +85°C to accommodate a broad range of industrial environments.
• Mounting and Packaging: Stud (bolt) mount screw-terminal radial can with φ90 × 205 L physical size and cardboard packing suitable for mass production environments.
• Series Advantages: LNC series offers smaller size and higher ripple current capability compared to related LNX/LNK series, and is designed to handle high-speed charge-discharge cycles and high-frequency regenerative voltages.
• RoHS Compliant: Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters: Energy storage and smoothing in inverter front-ends and DC bus applications where sustained ripple currents and high voltage rating are required.
• AC Servomotor Drives: Handling high-frequency regenerative voltage and rapid charge-discharge cycles encountered in servo systems.
• Power Supplies for Industrial Equipment: Bulk capacitance and ripple absorption for industrial power supplies used in automation and motor control.
• Regenerative Braking Circuits: Supports high-frequency ripple and transient energy during regenerative events in motor-drive systems.

Unique Advantages

• High Ripple Handling Across Frequencies: Dual ripple ratings (38.3 A at 120 Hz and 53.62 A at 100 kHz) provide validated performance for both low-frequency smoothing and high-frequency switching environments.
• Validated Endurance: 5,000-hour load life at 85°C under rated ripple and DC bias ensures predictable aging and maintenance planning for long-term deployments.
• Series-Level Design Optimized for Power Electronics: LNC series design targets smaller size and higher ripple performance compared to similar series, reducing board area and easing system-level thermal design.
• Robust Mechanical Mounting: Stud/bolt screw-terminal radial can construction simplifies secure mounting and high-current connections in industrial assemblies.
• Clear Performance Limits: Defined post-endurance limits for capacitance, tan δ, and leakage current enable straightforward qualification and lifecycle analysis.
• Regulatory Compliance: RoHS compliance supports restricted-substance requirements in modern equipment builds.
