LNT1K473MSE

The LNT1K473MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, offering 47,000 µF capacitance at an 80 V rating with ±20% tolerance. It is a radial can with screw terminals designed for general-purpose power applications that require high bulk capacitance and robust thermal performance.

Built for sustained operation up to +105°C, the LNT1K473MSE combines high stored energy with long-life endurance (2,000 hours at 105°C under rated ripple conditions) and RoHS compliance for deployed industrial and commercial designs.

Key Features

• High Capacitance — 47,000 µF nominal capacitance provides substantial bulk energy storage for smoothing and decoupling.
• 80 V Rated Voltage — Designed for higher-voltage power rails where elevated DC bus or intermediate circuit voltages are present.
• Robust Thermal Endurance — Rated for continuous operation from −40°C to +105°C with a guaranteed lifetime of 2,000 hours at +105°C under rated ripple conditions.
• Low-Loss Characteristic — Specified tangent of loss angle (tan δ) of 0.35 supports predictable dissipation behavior at 120 Hz, 20°C.
• Screw Terminal Package — Radial can with screw terminals enables secure bolted connections for high-current or serviceable installations; nominal mechanical size φ76.2 × 120 mm.
• Ripple Current Capability — Rated ripple current of 13.4 A at 120 Hz and 15.41 A at 100 kHz supports ripple handling in power systems and converters.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing on DC rails where high capacitance and 80 V rating are required.
• Power conversion and inverters — Supports ripple absorption and DC-link stabilization in converter topologies that operate within the specified voltage and temperature ranges.
• Industrial electronics — Use in control panels and equipment requiring durable screw-terminal connections and long-term operation at elevated temperatures.

Unique Advantages

• High stored energy per component — 47,000 µF at 80 V reduces the number of parallel capacitors needed for large bulk storage, simplifying BOM and layout.
• Serviceable screw terminals — Bolted connections provide reliable mechanical and electrical contact for high-current installations and field maintenance.
• Designed for elevated-temperature duty — 2,000-hour life at +105°C with rated ripple current gives predictable aging and replacement planning for thermal-stressed environments.
• measurable ripple handling — Specified ripple current ratings at both 120 Hz and 100 kHz enable selection based on frequency content of the application.
• Clear mechanical footprint — φ76.2 × 120 mm can size and radial screw-terminal packaging facilitate mechanical integration into rack- or chassis-mounted systems.
