LNT2D473MSEN

The LNT2D473MSEN is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications. It delivers 47 mF capacitance at a 200 V rating with polarized construction and is built for elevated-temperature operation up to +105°C.

As part of the LNT series, this screw-terminal capacitor provides high ripple-current capability and extended voltage coverage in a robust package suitable for industrial and power-system use where reliable bulk energy storage and smoothing are required.

Key Features

• Capacitance and Tolerance — 47 mF nominal with ±20% tolerance at 120 Hz, 20°C for predictable energy storage and decoupling.
• Rated Voltage — 200 V DC rating for medium-voltage power rails within the LNT series range.
• High Ripple Current — Rated ripple current of 19.9 A at 120 Hz and 23.88 A at 100 kHz, supporting heavy AC ripple in power circuits.
• Elevated Temperature Operation — Rated for operation from −25°C to +105°C, with load life specified at 2,000 hours at +105°C under rated ripple conditions.
• Screw Terminal Mounting — Radial, can-style package with screw terminals for secure, low-resistance connections in chassis- or bracket-mounted designs.
• Polarized Electrolytic — Polar construction for correct orientation in DC power applications.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).
• Package Size — Mechanical footprint listed as L: 25 × D: 9 cm to assist in mechanical integration and mounting planning.

Typical Applications

• General Power Supplies — Bulk energy storage and smoothing on medium-voltage DC rails where 200 V rating and high ripple capability reduce output ripple and support stable regulation.
• Industrial Power Modules — Filter and decoupling capacitor for power modules and converters that require operation up to +105°C and substantial ripple handling.
• Energy Storage / DC Link — Useful as a DC-link or reservoir capacitor in systems needing polarized bulk capacitance and reliable high-current ripple performance.

Unique Advantages

• High Ripple Handling: Ripple currents specified at both 120 Hz and 100 kHz enable designers to size capacitors for real-world switching and mains-frequency stresses.
• Elevated-Temperature Endurance: Rated endurance of 2,000 hours at +105°C under rated ripple current provides predictable long-term performance in hot operating environments.
• Screw-Terminal Reliability: Screw terminals provide low-impedance, secure connections for high-current paths and easy field wiring or replacement.
• Clear Mechanical Data: Provided package dimensions (L: 25 × D: 9 cm) simplify mechanical integration and bracket selection for chassis-mounted systems.
• Regulatory Compliance: RoHS compliance supports inclusion in designs targeting restricted-substance requirements.
