LNT2D473MSEB

The LNT2D473MSEB is a large-can aluminum electrolytic capacitor in a screw-terminal configuration designed for general-purpose power electronics. It delivers 47,000 µF of capacitance at a 200 V rating with a rugged radial can and screw terminals for secure mechanical and electrical connections.

Engineered for demanding ripple and bulk energy applications, this Nichicon LNT-series part combines high capacitance, substantial low- and high-frequency ripple handling, and an endurance rating at elevated temperature for reliable performance in long-running systems.

Key Features

• Capacitance & Tolerance — 47,000 µF nominal capacitance with a tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 200 V DC rating for medium- to high-voltage power systems.
• High Ripple Current Capability — Low-frequency ripple current: 19.9 A at 120 Hz; high-frequency ripple current: 23.88 A at 100 kHz, enabling effective smoothing under substantial AC ripple loads.
• Thermal & Endurance Specification — Operates from -25°C to +105°C with an endurance (load life) of 2000 hours at 105°C under rated ripple and DC bias conditions.
• Loss Factor — tanδ (DF) of 0.25 measured at 20°C, 120 Hz, useful for assessing AC loss and heating.
• Leakage Current — Specified leakage current of 5000 µA after initial application of rated voltage.
• Robust Screw-Terminal Package — Radial can with screw terminals (φ90 × 250L size; L: 25 cm × D: 9 cm) for secure mounting and high-current connections.
• Compliance & Packaging — RoHS compliant and shipped in cardboard packing; product is in mass production.

Typical Applications

• General-purpose power electronics — Bulk energy storage and smoothing where high capacitance and high-voltage capability are required.
• High-ripple DC link circuits — Use where substantial low- and high-frequency ripple currents (19.9 A at 120 Hz, 23.88 A at 100 kHz) must be handled reliably.
• Industrial power supplies — Suitable for systems that require long operating life at elevated temperatures (2000 h at 105°C) and robust screw-terminal connections.

Unique Advantages

• Large stored energy in a single component — 47,000 µF nominal provides significant bulk capacitance to reduce system footprint and BOM compared to multiple smaller capacitors.
• High ripple current handling — Rated ripple currents at both low and high frequencies support demanding smoothing and decoupling tasks under heavy AC stress.
• Designed for elevated-temperature operation — Specified for -25°C to +105°C with a defined 2000-hour endurance at 105°C for predictable life in hot environments.
• Secure electrical and mechanical termination — Screw-terminal radial can construction simplifies high-current connections and mechanical mounting for robust installations.
• Measurable loss characteristics — DF (tanδ) = 0.25 at 20°C, 120 Hz helps engineers estimate dissipation and thermal behavior during design.
• Regulatory alignment — RoHS compliant and available in mass-production quantities with cardboard packing for standard handling.
