LNT2C473MSE

The LNT2C473MSE is a high-capacitance, screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series. Designed for heavy-duty power applications, it delivers 47,000 µF at a 160 V rating in a large φ90 × 220 mm can with robust screw terminals for secure electrical and mechanical connections.

With a rated operating range of −25°C to +105°C and 2,000 hours endurance at 105°C under rated ripple conditions, this capacitor is intended for general-purpose industrial power systems that require high bulk capacitance, significant ripple-handling capability, and reliable long-term performance.

Key Features

• High Capacitance: 47,000 µF (47 mF) for bulk energy storage and smoothing in DC-link and power-supply systems.
• Rated Voltage: 160 V working voltage suitable for medium-voltage power rails and energy buffer applications.
• Screw Terminal Mounting: Radial can with screw terminals enables secure, low-resistance connections and simplified mechanical mounting for heavy-current systems.
• Ripple Current Capability: 17.2 A at 120 Hz (low frequency) and 20.64 A at 100 kHz (high frequency) to support demanding ripple and transient loads.
• Thermal and Endurance Specification: Operates from −25°C to +105°C with a rated life of 2,000 hours at 105°C under rated ripple conditions.
• Electrical Loss Characteristics: Tangent of loss angle (tan δ) 0.25 measured at 20°C, 120 Hz for predictable dissipation behavior.
• Leakage Current: Specified leakage current of 5,000 µA for initial performance planning and bias considerations.
• Packaging and Compliance: Supplied in cardboard packing and compliant with RoHS requirements.

Typical Applications

• Power Supplies and DC-Link Storage: Bulk smoothing and energy buffering on medium-voltage power rails requiring large capacitance and high ripple current handling.
• Inverters and Motor Drives: DC-link and filtering in industrial inverters and motor-control systems where robust terminals and high ripple capability are essential.
• Industrial UPS and Energy Backup: Energy storage and supply stabilization for uninterruptible power systems and backup power modules.
• Power Conditioning: Filtering and transient suppression in power-conditioning equipment for industrial and commercial installations.

Unique Advantages

• Substantial Energy Density: 47,000 µF at 160 V provides large bulk capacitance in a single component, reducing the number of parallel devices required.
• High Ripple Tolerance: Rated ripple current values (17.2 A at 120 Hz and 20.64 A at 100 kHz) support sustained heavy-current operation and reduce thermal stress on the capacitor.
• Robust Mechanical Connection: Screw terminal construction ensures low-resistance, durable electrical connections suitable for repeated assembly and high-current bus work.
• Wide Operating Temperature Range: −25°C to +105°C operation and 2,000-hour endurance at 105°C provide predictable lifetime behavior for industrial deployments.
• Measured Dissipation Data: Specified tan δ (0.25 at 20°C, 120 Hz) helps engineers estimate power loss and thermal design requirements accurately.
• Regulatory Compliance: RoHS compliance simplifies environmental qualification for regulated markets.
