LNC2W103MTEJ

The LNC2W103MTEJ is a stud/bolt-mount screw-terminal aluminum electrolytic capacitor from Nichicon's LNC series. It provides high-voltage, high-capacitance energy storage in a compact radial can with screw terminals, engineered for demanding industrial power electronics.

Designed for inverter and regenerative power applications, this 10,000 µF, 450 V capacitor delivers high ripple-current capability and a rated life of 5000 hours at 85°C, making it suitable for systems that require robust high-frequency charge–discharge performance and long-term endurance.

Key Features

• High Capacitance, High Voltage: 10,000 µF (10 mF) nominal capacitance at a 450 V rated voltage for bulk energy storage in high-voltage power rails.
• Stud Bolt Mount / Screw Terminals: Stud/bolt mount with screw-terminal radial can package for secure mechanical and electrical connection in industrial assemblies.
• High Ripple Current: Low-frequency ripple capability of 34.1 A at 120 Hz and high-frequency ripple capability of 47.74 A at 100 kHz to support inverter and regenerative loads.
• Endurance and Reliability: Rated life of 5000 hours at 85°C with specified endurance characteristics after DC bias plus rated ripple current are applied.
• Temperature Range: Operates from −40°C to +85°C to accommodate a wide span of industrial ambient conditions.
• Electrical Loss and Leakage: Specified tangent of loss angle (tan δ) of 0.2 measured at 20°C, 120 Hz and leakage current specified at 5000 µA.
• Compact Form Factor: φ90 × 155 mm can size delivers a smaller footprint with high ripple capability compared to prior LNC-family variants.
• RoHS Compliant & Packaging: Compliant with RoHS and supplied in cardboard packing for standard logistics handling.

Typical Applications

• Industrial Inverters: Energy buffering and DC link smoothing in inverter power supplies where 450 V DC rails and high ripple handling are required.
• AC Servomotor Drives: Regenerative voltage absorption and high-frequency charge–discharge cycles in servo drive regenerative circuits.
• Power Electronics Modules: Bulk energy storage and ripple suppression in high-voltage power conversion equipment and industrial motor drives.

Unique Advantages

• High ripple capability: Rated ripple currents at both low and high frequencies (34.1 A at 120 Hz; 47.74 A at 100 kHz) reduce system heating and improve performance under heavy AC loading.
• Long endurance at elevated temperature: 5000 hours rated life at 85°C provides predictable aging and service life for industrial applications.
• Secure mechanical mounting: Stud/bolt mount and screw terminals simplify installation and ensure reliable connections in vibration-prone environments.
• Wide operating temperature range: −40°C to +85°C operation supports a broad set of industrial ambient conditions without derating outside stated limits.
• High-voltage energy storage: 10,000 µF at 450 V offers substantial bulk capacitance for DC link stabilization and transient energy demands.
