LNT2A473MSEN

The LNT2A473MSEN is a screw-terminal aluminum electrolytic capacitor designed for high-capacitance, high-ripple power applications. It provides 47,000 µF at 100 V in a radial can with screw terminals, offering a compact solution for bulk energy storage and smoothing in general-purpose power designs.

Key value propositions include high ripple-current capability at both low and high frequencies, a 2000-hour endurance rating at 105°C, and a wide operating temperature range for demanding electrical environments.

Key Features

• Capacitance & Voltage — 47,000 µF (47 mF) rated at 100 V for large bulk energy storage and smoothing in power circuits.
• High ripple-current capability — 17.0 A low-frequency ripple current (120 Hz) and 19.55 A high-frequency ripple current (100 kHz) to support high-stress power applications.
• Endurance & Temperature — Rated for 2,000 hours at 105°C under specified ripple conditions; operating temperature range −40°C to +105°C.
• Leakage and loss characteristics — Leakage current specified at 5,000 µA and tan δ of 0.3, enabling predictable loss and leakage behavior for design margining.
• Robust mechanical package — Radial can with screw terminals (φ90 × 140L form factor) and M5 bolt nominal terminal sizing for secure, low-resistance connections.
• Compliance & Production — RoHS-compliant and supplied in cardboard packing for mass-production applications.

Typical Applications

• Power supply bulk filtering — Use where large capacitance and high ripple handling are required to smooth DC outputs at up to 100 V.
• DC link and energy storage — Suitable for designs that need 47,000 µF of stored charge and high ripple-current endurance in a screw-terminal package.
• Industrial power electronics — Applicable to general-purpose industrial power modules that operate across −40°C to +105°C and demand long endurance at elevated temperature.

Unique Advantages

• Large capacitance in a single component: 47,000 µF provides significant bulk energy storage that can reduce the need for parallel capacitor banks.
• High ripple-current rating: 17 A (120 Hz) and 19.55 A (100 kHz) ratings support heavy AC ripple environments and reduce thermal stress on the capacitor.
• Thermal endurance: 2,000-hour life at 105°C under rated ripple current delivers predictable long-term performance in hot operating conditions.
• Screw-terminal reliability: Radial can with screw terminals offers robust, low-impedance connections for high-current power paths.
• Predictable leakage and dissipation: Specified leakage current (5,000 µA) and tan δ (0.3) enable accurate power-loss and hold-up calculations.
• RoHS compliant and production ready: Supplied for mass production with cardboard packing to support manufacturing logistics and compliance needs.
