LNT2A473MSE

The LNT2A473MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, rated 100 V with 47,000 µF capacitance. Designed for general-purpose power applications, it combines very high bulk capacitance with screw-terminal mounting for secure electrical and mechanical connections.

Key value propositions include high ripple handling, extended operating temperature range to +105°C, and a 2,000-hour rated life at 105°C when operated at rated ripple current for this voltage class. The part is RoHS compliant and supplied in cardboard packing for production use.

Key Features

• High Capacitance — 47,000 µF bulk capacitance for energy storage and smoothing in high-demand circuits.
• 100 V Rated Voltage — Suitable for systems requiring a 100 V DC working voltage.
• High Ripple Current — 17.00 A at 120 Hz (low frequency) and 19.55 A at 100 kHz (high frequency) for effective ripple absorption under heavy load.
• Endurance at Elevated Temperature — Rated lifetime of 2,000 hours at 105°C when subjected to rated ripple current (applies to 10–250 V range).
• Operating Temperature Range — −40°C to +105°C to accommodate a wide range of thermal environments.
• Electrical Characteristics — ±20% capacitance tolerance and tan δ = 0.3 (max) for predictable performance; leakage current specified at 5,000 µA.
• Screw-Terminal, Radial Can Package — Screw terminal mounting and radial can construction (φ90×140L) for secure panel or bracket mounting and high-current connections.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.
• Production Ready — Mass production status with cardboard packing for handling and shipment.

Typical Applications

• Power Supply Filtering — Bulk smoothing and energy storage in general-purpose DC power supplies where high capacitance and 100 V rating are required.
• DC Link and Energy Storage — Bulk capacitance for DC-link circuits and intermediate energy storage in industrial and commercial power electronics.
• Hold-Up / Backup Power — Short-term energy reserve and voltage stabilization in control systems and power subsystems.

Unique Advantages

• Substantial Bulk Energy Capacity: 47,000 µF provides large charge storage for smoothing and transient support, reducing the need for multiple smaller capacitors.
• High Ripple Endurance: 17 A (120 Hz) and 19.55 A (100 kHz) ripple ratings enable reliable operation under significant AC stress at both low and high frequencies.
• Temperature-Rated Reliability: Rated to operate up to 105°C with a defined 2,000-hour life at that temperature for the 100 V class, supporting sustained high-temperature operation.
• Robust Mechanical Termination: Screw terminals provide secure, low-resistance connections suited to high-current wiring and repeatable assembly processes.
• Predictable Electrical Behavior: Specified tolerance (±20%), tan δ, and leakage current enable engineers to design predictable filtering and energy-storage solutions.
• Regulatory Compliance: RoHS compliance supports use in products requiring restricted-substance conformity.

Why Choose LNT2A473MSE?

The LNT2A473MSE is positioned for designs that need large bulk capacitance combined with substantial ripple handling and reliable operation up to +105°C. Its screw-terminal radial can package supports secure, high-current connections while the 100 V rating provides headroom for many industrial and commercial power systems.

This capacitor is appropriate for engineers specifying general-purpose power smoothing, DC-link energy storage, or hold-up applications where a balance of capacitance, ripple capability, and thermal endurance drives long-term performance and reduced system complexity.
