LNT2G472MSEH

The LNT2G472MSEH is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNT series, delivering 4700 µF (4.7 mF) capacitance at a 400 V rating. It is a radial can with screw terminals, designed for general-purpose power applications that require high ripple current handling and extended operation at elevated temperatures.

Key value propositions include high-voltage energy storage (400 V), high ripple-current capability at both low and high frequencies, a broad operating temperature range of −25 °C to +105 °C, and RoHS compliance for environmental compatibility.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) nominal capacitance with a 400 V rated voltage and ±20% tolerance, providing substantial bulk energy storage for high-voltage systems.
• High Ripple Current — Rated ripple current of 20.3 A at 120 Hz and 28.42 A at 100 kHz, enabling effective smoothing under heavy AC ripple conditions.
• Temperature and Endurance — Operating temperature range −25 °C to +105 °C with a rated lifetime of 5000 hours at 105 °C, supporting sustained operation in elevated-temperature environments.
• Screw-Terminal Radial Can — Robust screw terminal mounting (radial, can with screw terminals) for secure electrical and mechanical connections in industrial assemblies.
• Polarized Aluminum Electrolytic — Polarized construction suitable for DC bias applications where polarized capacitors are required.
• Physical Dimensions — Compact can dimensions: length 13 cm × diameter 7.62 cm; Height seated max specified as 5.118 inches, facilitating layout and mechanical planning.
• Regulatory — RoHS compliant, meeting applicable environmental directive requirements.

Typical Applications

• High-voltage power filtering — Bulk filtering in 400 V DC systems where 4700 µF capacitance and high ripple-current handling reduce voltage ripple and stabilize DC rails.
• DC link and energy storage — DC link capacitance and short-term energy buffering in power-conversion equipment that require robust screw-terminal connections and long endurance at elevated temperature.
• Industrial power electronics — Use in industrial power supplies and converters that demand high-voltage electrolytic capacitance and durable operation up to +105 °C.

Unique Advantages

• High-voltage energy density: 4700 µF at 400 V provides significant stored energy per component for compact high-voltage designs.
• Proven ripple performance: Specified ripple currents at 120 Hz and 100 kHz (20.3 A and 28.42 A respectively) support both mains-frequency smoothing and high-frequency switching environments.
• Long elevated-temperature life: Rated for 5000 hours at 105 °C, enabling predictable service life in thermally demanding installations.
• Secure, serviceable termination: Screw terminals offer reliable electrical contact and straightforward installation or replacement in field-serviceable equipment.
• Regulatory compliance: RoHS conformity simplifies use in designs subject to environmental directive requirements.
