LNT2D473MSE

The LNT2D473MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNT series, designed for general-purpose power applications that require large bulk capacitance at elevated voltages. It pairs a 47,000 µF capacitance with a 200 V rating in a radial can with screw terminals for robust electrical connections.

Engineered for operation from −25°C to +105°C with a rated endurance of 2,000 hours at 105°C, this part delivers high ripple-current capability and stable performance for demanding AC ripple and DC-bias environments.

Key Features

• High Capacitance and Voltage: 47,000 µF at a 200 V rated voltage provides substantial bulk energy storage for high-voltage power systems.
• Screw-Terminal Packaging: Radial can with screw terminals enables secure, low-impedance connections suitable for heavy-current bus applications.
• Ripple Current Capacity: Supports 19.9 A at 120 Hz (low-frequency) and 23.88 A at 100 kHz (high-frequency), allowing sustained AC ripple handling.
• Thermal and Endurance Ratings: Rated for −25°C to +105°C with a life/endurance specification of 2,000 hours at 105°C under rated ripple and bias conditions.
• Electrical Characteristics: Capacitance tolerance ±20% (120 Hz, 20°C), tangent of loss angle (tan δ) 0.25 at 20°C/120 Hz, and leakage current specified at 5,000 µA.
• Physical Size & Packing: Compact axial dimensions φ90 × 250 L (L: 25 cm × D: 9 cm) in cardboard packing for mass production handling.
• RoHS Compliant: Manufactured in compliance with RoHS requirements.

Typical Applications

• General-Purpose Power Systems: Bulk smoothing and energy storage in systems that require a 200 V rated capacitor with large capacitance for voltage stabilization.
• High-Ripple DC Circuits: DC link and filtering roles where sustained ripple currents up to 19.9 A (120 Hz) or 23.88 A (100 kHz) are expected.
• Industrial Power Electronics: Applications that benefit from screw-terminal mounting and robust mechanical/electrical connections for high-current bus installations.

Unique Advantages

• Large Bulk Capacitance: 47,000 µF provides significant reservoir capacity to stabilize rails and absorb transient loads.
• High Voltage Support: 200 V rating allows deployment in higher-voltage power stages without series arrangements.
• Robust Connection Method: Screw terminals offer secure, low-resistance attachment suitable for repeated installation and high-current wiring.
• Sustained Ripple Handling: Specified ripple currents at both low and high frequency help meet AC ripple demands in converters and power supplies.
• Designed for Elevated Temperatures: Rated to operate up to 105°C with a 2,000-hour endurance figure, supporting reliability in thermally challenging environments.
• Clear Electrical Spec Limits: Defined leakage (5,000 µA), tan δ (0.25 at 20°C/120 Hz) and ±20% capacitance tolerance simplify margin and thermal budget calculations.
