LNT1H473MSEN

The LNT1H473MSEN is a screw terminal aluminum electrolytic capacitor from Nichicon’s LNT series, offering 47,000 µF capacitance at a 50 V rating in a φ63.5 × 100 mm can. It is a polar, radial can device designed for general-purpose applications that require high bulk capacitance and robust ripple-current handling.

Designed for operation from −40°C to +105°C with a rated endurance of 2,000 hours at 105°C, this capacitor addresses applications where substantial energy storage, smoothing and stability under elevated temperature and continuous ripple are required.

Key Features

• Capacitance & Voltage — 47,000 µF nominal capacitance with a 50 V rated voltage and tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-resistance connections; φ63.5 terminal pitch and nominal M5 bolt size for the φ63.5 body.
• Thermal and Life Rating — Operating temperature range −40°C to +105°C with a guaranteed life/endurance of 2,000 hours at 105°C under rated ripple conditions.
• High Ripple-Current Capability — Low-frequency ripple current of 9.9 A (120 Hz) and high-frequency ripple current of 11.38 A (100 kHz), enabling continuous ripple duty.
• Electrical Loss & Leakage — Tangent of loss angle (tan δ) 0.35 (measured at 20°C, 120 Hz) and specified leakage current of 4,590 µA.
• Packaging & Compliance — Supplied in cardboard packing; RoHS‑compliant and available in mass production.

Typical Applications

• General-purpose power filtering — Bulk capacitance for smoothing and decoupling in power supply stages where high capacitance and robust ripple handling are required.
• Energy storage and buffering — Local energy reservoir for systems that need transient energy delivery or voltage stabilization over broad temperature ranges.
• Industrial and commercial power equipment — Suitable for general-purpose use in assemblies that require screw-terminal mounting and high-capacitance bulk components.

Unique Advantages

• Large bulk capacitance: 47,000 µF provides substantial energy storage in a single component, reducing the need for multiple parallel parts.
• Secure screw-terminal connections: Radial can with screw terminals and M5-compatible hardware for reliable mechanical and electrical attachment.
• High continuous ripple capability: Rated ripple currents of 9.9 A (120 Hz) and 11.38 A (100 kHz) support sustained AC ripple loading without compromising performance.
• Wide operating temperature and qualified life: −40°C to +105°C range and 2,000 hours endurance at 105°C give predictable behavior in elevated-temperature environments.
• Measurable electrical performance: Specified tan δ (0.35 at 20°C, 120 Hz) and quantified leakage current (4,590 µA) allow designers to assess loss and standby draw precisely.
• RoHS compliance and production availability: Compliant with RoHS and available in mass production for consistent supply.

Why Choose LNT1H473MSEN?

The LNT1H473MSEN combines very high capacitance and robust ripple-current capability in a screw-terminal radial can, making it a practical choice for designs that need single-component bulk energy storage with secure mounting. Its −40°C to +105°C operating window and defined 2,000-hour endurance at 105°C provide predictable performance under thermal stress.

This capacitor is well suited for engineers specifying high-capacitance, general-purpose electrolytic components from a recognized manufacturer (Nichicon) where measurable electrical characteristics, secure screw-terminal connections, and RoHS compliance are priorities.
