LNT1J473MSEB

The LNT1J473MSEB from Nichicon is a screw-terminal, aluminum electrolytic capacitor providing 47,000 µF capacitance at a 63 V rating in a radial can with screw terminals. It is designed for general-purpose power applications that require large bulk capacitance, secure screw-terminal connections and operation up to +105°C.

As part of the LNT series, this product benefits from series-level design choices such as extended rated voltage options and larger case-size availability, while offering verified ripple-current handling and polarized radial mounting for robust power-system use.

Key Features

• High Capacitance — 47,000 µF (47 mF) nominal capacitance for robust bulk energy storage and smoothing.
• 63 V Rated Voltage — Designed and specified for a 63 V nominal system voltage.
• Screw-Terminal Mounting — Radial can with screw terminals for secure, low-resistance electrical and mechanical connections.
• High-Temperature Operation — Rated for operation to +105°C, supporting elevated-temperature power environments.
• Endurance and Lifetime — Series load-life capability noted at 5,000 hours; this part lists a lifetime at +105°C of 2,000 hours under specified conditions.
• Ripple Current Capability — 11.2 A at 120 Hz and 12.88 A at 100 kHz, enabling handling of substantial ripple in power circuits.
• Polarized Aluminum Electrolyte — Polar capacitor construction for DC bulk storage applications; capacitance tolerance ±20% at 120 Hz, 20°C.
• RoHS Compliant — Meets the RoHS directive requirements (2011/65/EU, (EU)2015/863).
• Compact, Defined Footprint — Physical size φ63.5 × 120 mm (L: 12 × D: 6.35 cm) suitable for chassis- or bracket-mounted installations.

Typical Applications

• General-Purpose Power Systems — Bulk energy storage and smoothing where a high-capacitance, screw-terminal capacitor is required.
• High-Temperature Environments — Applications requiring continuous operation up to +105°C while sustaining rated ripple current.
• High-Ripple Current Circuits — Power supplies and converters where the specified ripple-current ratings (11.2 A @120 Hz, 12.88 A @100 kHz) are needed to manage ripple and transient loads.
