LNT1K473MSEN

The LNT1K473MSEN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, offering 47,000 µF (47 mF) capacitance at a rated voltage of 80 V with ±20% tolerance. Built as a radial can with screw terminals (φ76.2 × 120 mm), it targets general-purpose power-electronic applications that require large bulk capacitance, high ripple handling and robust thermal endurance.

Key electrical and reliability characteristics include a low-frequency ripple current of 13.4 A (120 Hz), a high-frequency ripple current of 15.41 A (100 kHz), a specified leakage current of 5,000 µA, a maximum tanδ of 0.35, and a rated operating range of −40°C to +105°C with a 2,000 hour life at 105°C.

Key Features

• High Capacitance at 80 V — 47,000 µF (47 mF) provides substantial bulk energy storage for smoothing and decoupling tasks in power systems.
• Screw Terminal Mounting — Radial can with screw terminals designed for secure, high-current connections and easy installation in chassis or power assemblies.
• Robust Ripple Current Capability — 13.4 A at 120 Hz and 15.41 A at 100 kHz enable sustained AC stress handling for both low- and high-frequency ripple environments.
• Thermal Endurance — Rated for continuous operation from −40°C to +105°C with a specified lifetime of 2,000 hours at 105°C under rated ripple/current conditions.
• Leakage and Loss Control — Specified leakage current of 5,000 µA and a maximum tanδ of 0.35 to help characterize standby losses and dissipation for system power budgets.
• Form Factor & Packaging — Large-diameter radial can (φ76.2 × 120 mm) with cardboard packing, supplied for mass production environments.
• RoHS Compliant — Meets RoHS environmental requirements as indicated in the product data.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy storage where high capacitance and 80 V rating are required to stabilize DC rails.
• Power electronics assemblies — DC-link or filter capacitor in general-purpose inverters, motor drives and converters that need large capacitance and high ripple endurance.
• Industrial power systems — Energy buffering and transient suppression in industrial control and power distribution modules operating within −40°C to +105°C.

Unique Advantages

• Large single-component bulk capacitance: 47,000 µF at 80 V reduces the number of parallel parts required for equivalent energy storage.
• High ripple handling across frequencies: Separate low-frequency (13.4 A at 120 Hz) and high-frequency (15.41 A at 100 kHz) ratings let designers quantify performance for mixed-ripple environments.
• Designed for harsh thermal conditions: −40°C to +105°C operating range and 2,000 hour endurance at 105°C provide predictable ageing and performance in elevated-temperature applications.
• Screw-terminal reliability: Robust mechanical and electrical connection suited for high-current, vibration-prone assemblies.
• Clear loss and leakage specifications: Defined tanδ (0.35) and leakage current (5,000 µA) support accurate thermal and standby power budgeting.
• Production-ready packaging: Cardboard packing and mass-production status streamline procurement and assembly planning.
