LNT1J473MSEN

The LNT1J473MSEN is an aluminum electrolytic capacitor in Nichicon’s LNT series, featuring a screw-terminal radial can design and 47,000 µF capacitance at 63 V. It is intended for general-purpose applications that require large capacitance, substantial ripple-current handling, and a robust screw-terminal mounting style.

This part is specified for operation from −40°C to +105°C, with a rated endurance of 2000 hours at 105°C. It is supplied in cardboard packing and is RoHS compliant.

Key Features

• High Capacitance: 47,000 µF (47 mF) providing bulk energy capacity for DC link, smoothing, or storage applications.
• Rated Voltage: 63 V rated voltage suitable for medium-voltage DC systems within the product’s specified rating.
• Screw-Terminal Mounting: Radial can with screw terminals (M5 nominal bolt for φ63.5 case) for secure electrical and mechanical connection.
• High Ripple-Current Capability: Low-frequency ripple current 11.2 A (120 Hz) and high-frequency ripple current 12.88 A (100 kHz) to support demanding AC ripple conditions.
• Operating Temperature and Endurance: Specified for −40°C to +105°C with a rated life of 2000 hours at 105°C under rated ripple/voltage conditions.
• Electrical Characteristics: Capacitance tolerance −20% to +20% and leakage current specified as 5000 µA.
• Form Factor: Size φ63.5 × 120 mm (L: 12 × D: 6.35 cm), radial can with screw terminals for compact, serviceable installation.
• Regulatory Compliance: RoHS compliant.

Typical Applications

• Power-supply bulk capacitance: Large capacitance and high ripple-current ratings support bulk energy storage and smoothing in power-supply designs.
• DC link and filtering: Suitable where sustained ripple currents and elevated operating temperatures are present, leveraging the 11.2 A (120 Hz) and 12.88 A (100 kHz) ripple-current specifications.
• General-purpose industrial equipment: Designed for general-purpose use cases that require a high-capacitance, screw-terminal aluminum electrolytic solution within −40°C to +105°C range.

Unique Advantages

• Substantial bulk energy capacity: The 47,000 µF capacitance reduces the number of components required to achieve the same stored charge, simplifying BOM for high-capacitance needs.
• High ripple-current endurance: Rated LF and HF ripple currents (11.2 A / 12.88 A) allow the capacitor to handle significant AC stress without immediate derating, improving system reliability under ripple loads.
• Screw-terminal reliability and serviceability: Screw terminals provide secure electrical connection and straightforward installation or replacement in assembled systems.
• Wide operating temperature window: −40°C to +105°C rating and a defined 2000-hour life at 105°C support deployments in elevated-temperature environments where long-term performance is required.
• Clear specification set: Defined tolerance, leakage current, physical dimensions, and packaging details enable predictable integration and procurement.
