LNT1C473MSEN

The LNT1C473MSEN from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series designed for general-purpose power applications. It is a polarized, radial can capacitor rated for 16 V with 47 mF capacitance and a ±20% tolerance.

Built to operate across a wide temperature range and to withstand high ripple conditions, this screw-terminal unit is aimed at equipment requiring robust bulk capacitance, secure mechanical connections and thermal endurance up to +105°C.

Key Features

• Capacitance & Voltage — 47 mF nominal capacitance at a rated voltage of 16 V, with ±20% tolerance (measured at 120 Hz, 20°C).
• Screw Terminal Mounting — Radial can package with screw terminals for secure, high-current connections and easy installation in power systems.
• High Ripple Current — Rated ripple current of 6.8 A at 120 Hz and 7.82 A at 100 kHz, supporting applications with significant AC superposition on DC rails.
• Temperature Range & Endurance — Operating range −40°C to +105°C. Load-life specification of 2,000 hours at +105°C when rated ripple current is applied (per series endurance specification for 10 to 250 V products).
• Leakage Current Specification — Leakage current conforms to the series specification after five minutes’ application of rated voltage (series formula and limits provided in the LNT datasheet; measurement at 20°C).
• Mechanical Size and Form Factor — Radial, screw-terminal can with size dimensions L: 10 × D: 3.5 cm and a maximum seated height of 3.937 inch, suitable where larger bulk capacitance is required.
• RoHS Compliant — Manufactured to comply with RoHS directive (2011/65/EU, (EU)2015/863).
• Series Flexibility — Part of the Nichicon LNT series, which covers rated voltages from 10 V to 500 V and extended diameter/length options within the series.
• Low-temperature Stability — Impedance performance at low temperature: Z(–25°C)/Z(+20°C) ≤ 8 and Z(–40°C)/Z(+20°C) ≤ 12 for the 10–100 V range, per series specifications.

Typical Applications

• Power supply bulk smoothing — Provides high bulk capacitance and high ripple capability for DC bus smoothing and energy buffering in power supplies.
• Industrial power equipment — Screw terminals and high ripple rating suit industrial controllers, converters and inverters where secure connection and thermal endurance are required.
• Backup and hold-up energy storage — Large capacitance and robust endurance at +105°C make it suitable for short-term energy storage and hold-up in commercial equipment.

Unique Advantages

• High ripple-current capacity: Supports demanding AC+DC stress with 6.8 A (120 Hz) and 7.82 A (100 kHz) ratings, reducing the need for parallel banks in many designs.
• Screw-terminal reliability: Mechanical screw connections deliver secure, low-resistance terminations for high-current power paths and easier maintenance.
• Thermal endurance for elevated operating temperatures: Rated for continuous operation to +105°C with a documented load-life performance at that temperature.
• Large bulk capacitance in a single device: 47 mF provides substantial energy storage in a single component, simplifying layout and lowering component count.
• Series-backed flexibility: As part of the LNT family, it aligns with a broader range of voltage and size options for system scalability.
• Regulatory compliance: RoHS conformity supports use in designs subject to European restricted-substance requirements.
