LNT1H473MSE

The LNT1H473MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNT series, delivering 47 mF (47,000 µF) at a 50 V rating. It is a radial can with screw terminals designed for general-purpose power applications that require high capacitance and substantial ripple-current capability.

Key value propositions include large capacitance in a φ63.5 × 100L package, high low- and high-frequency ripple current handling, and rated operation up to 105°C with a defined 2,000-hour endurance at that temperature for 10–250 V parts such as this unit.

Key Features

• Capacitance & Voltage: 47 mF (47,000 µF) nominal capacitance at 50 V with a capacitance tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Screw Terminal Package: Radial can with screw terminals (φ63.5 × 100L) for secure, low-inductance connections suitable for high-current bus applications.
• High Ripple Current Performance: Low-frequency ripple current 9.9 A at 120 Hz and high-frequency ripple current 11.38 A at 100 kHz, enabling effective smoothing under heavy ripple loads.
• Operating Temperature & Life: Rated for −40°C to +105°C. Endurance specified as 2,000 hours at 105°C for 10–250 V ratings (product-specific life per series documentation).
• Leakage & Loss Characteristics: Specified leakage current of 4,590 µA; tan δ (dissipation factor) measured at 20°C, 120 Hz per datasheet conditions.
• Production & Compliance: RoHS compliant, packaged in cardboard packing, and listed as mass production status.

Typical Applications

• Power supply bulk filtering: Large capacitance and high ripple-current ratings make the LNT1H473MSE suitable for bulk energy smoothing and decoupling in power supplies.
• DC bus smoothing for industrial converters: Screw terminal connections and robust ripple handling support DC bus stabilization in motor drives and industrial power converters.
• Uninterruptible power systems and energy buffering: The high capacitance provides transient energy storage and buffering where sustained capacitance and elevated temperature operation are required.

Unique Advantages

• High stored energy in a single component: 47 mF at 50 V simplifies designs by reducing the number of parallel capacitors needed for equivalent bulk capacitance.
• Robust ripple-current capability: 9.9 A (120 Hz) and 11.38 A (100 kHz) ratings support heavy ripple environments without frequent thermal derating.
• Screw-terminal electrical and mechanical reliability: Screw terminals (φ63.5 package) provide secure, low-impedance connections for high-current and high-vibration installations.
• High-temperature endurance: Rated to operate up to 105°C with a defined 2,000-hour life at that temperature for this voltage class, supporting demanding thermal environments.
• Production-ready and compliant: RoHS compliance, cardboard packing, and mass-production status ease procurement and integration into production BOMs.
