LNT2H472MSEH

The LNT2H472MSEH is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series. It delivers high-capacitance, high-voltage performance in a radial can with screw terminals for secure electrical and mechanical connections. Designed for general-purpose applications, this part targets circuits that require bulk energy storage and high ripple-handling capability at elevated voltages and temperatures.

Key Features

• Capacitance and Voltage — 4,700 µF (4.7 mF) nominal capacitance with a 500 V rated voltage and capacitance tolerance of −20% to +20%.
• High Ripple Capability — Low-frequency ripple current of 17.2 A (120 Hz) and high-frequency ripple current of 24.08 A (100 kHz), enabling sustained AC loading within specified limits.
• Electrical Loss — Tangent of loss angle (tan δ) specified at 0.2, measured at 20°C and 120 Hz, for predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 4,590 µA after specified conditions.
• Thermal and Lifetime Rating — Operating temperature range of −25°C to +105°C with a rated life/endurance of 2,000 hours at 105°C under rated ripple conditions.
• Mechanical Package — Radial can with screw terminals; physical size φ76.2 × 190 mm (diameter × length). Mounting and terminal dimensions follow LNT series screw-terminal configurations.
• Polarized Design — Polarized electrolytic construction for DC bulk and filtering applications.
• Packaging and Compliance — Supplied in cardboard packing and RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk smoothing and energy reserve in circuits that require 4.7 mF at up to 500 V.
• High-voltage energy storage — DC link and energy-hold applications that need a 500 V-rated, screw-terminal electrolytic capacitor for secure connections.
• High-ripple power systems — Applications where sustained ripple currents up to 24.08 A and operation to 105°C are required.

Unique Advantages

• High voltage at high capacitance: Provides 4.7 mF at a 500 V rating, enabling reduced component count where large capacitance at high voltage is needed.
• Robust screw-terminal mounting: Screw terminals support reliable electrical contact and mechanical fastening for heavy-current and serviceable installations.
• Designed for sustained ripple: Specified low- and high-frequency ripple current ratings allow predictable performance under continuous AC loading.
• Elevated operating temperature and defined life: Rated for −25°C to +105°C with a 2,000-hour endurance at 105°C, allowing designers to plan for long-term thermal performance.
• Clear electrical dissipation spec: tan δ = 0.2 at 20°C, 120 Hz, for predictable loss and thermal management calculations.
• RoHS compliant and packaged for handling: Meets RoHS requirements and is shipped in cardboard packing for protection during storage and assembly.
