LNT1V473MSEB

The LNT1V473MSEB is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, offering 47,000 µF nominal capacitance at a 35 V rating in a φ51 × 100L radial can with screw terminals. It is designed for general-purpose applications that require high bulk capacitance, high ripple-current capability, and long-term operation up to 105°C.

Key performance attributes include a wide operating temperature range (−40°C to +105°C), rated endurance at 105°C, and RoHS compliance, making it suitable for industrial and power-electronics assemblies that use screw-terminal mounting.

Key Features

• Bulk Capacitance & Voltage — 47 mF (47,000 µF) nominal capacitance at 35 V with a tolerance of −20% to +20%, providing large charge storage in a single component.
• Package & Mounting — Radial can with screw terminals (φ51 × 100L); terminal pitch and hardware accommodate M5 bolts for reliable electrical and mechanical connection.
• High Ripple Current — Low-frequency ripple current of 8.4 A (120 Hz) and high-frequency ripple current of 9.66 A (100 kHz), supporting high-current DC applications and filtering tasks.
• Electrical Loss & Leakage — Specified tanδ (DF) of 0.4 measured at 20°C, 120 Hz, and a measured leakage current of 3,840 µA for predictable performance parameters.
• Temperature & Endurance — Rated for operation from −40°C to +105°C with an endurance (load life) of 2,000 hours at 105°C under rated ripple/current conditions for 10–250 V parts.
• Compliance & Packaging — RoHS-compliant material construction and supplied in cardboard packing; part is in mass production.

Typical Applications

• General-purpose power electronics — For systems that require large bulk capacitance and screw-terminal mounting, such as cabinet-level power modules and DC bus stabilization.
• High-current filtering assemblies — Suited to assemblies where high ripple-current handling (8.4 A @120 Hz, 9.66 A @100 kHz) is required for smoothing and decoupling at 35 V.
• Industrial equipment — Applicable in industrial designs that demand operation across −40°C to +105°C and robust, bolt-down terminals for secure electrical connections.

Unique Advantages

• Substantial single-component capacitance: 47,000 µF reduces the need for multiple parallel parts when large bulk storage is required.
• Screw-terminal reliability: M5-compatible screw terminals provide mechanically secure, low-resistance connections for high-current installations.
• Dual-frequency ripple capability: Rated ripple-current values at both low and high frequencies help designers manage thermal and AC stress across operating conditions.
• High-temperature endurance: 2,000-hour life at 105°C (for this voltage class) gives predictable aging and replacement planning in elevated-temperature environments.
• Measured loss and leakage data: Specified tanδ and leakage current values enable straightforward thermal and leakage budgeting during system design.
