LNC2H472MSEJ

The LNC2H472MSEJ is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNC series. It provides 4700 µF (4.7 mF) capacitance at a 500 V rated voltage in a smaller-sized, radial screw-terminal can.

Designed for industrial power electronics, this capacitor is suited for inverter circuitry and high-frequency regenerative voltage systems such as AC servomotor drives and general inverters. Key value propositions include high ripple-current capability, a long 5000-hour load life at 85°C, and RoHS compliance.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) rated at 500 V for bulk energy storage in high-voltage applications.
• Screw Terminal Mounting — Radial can with screw terminals for secure, high-current connections in industrial assemblies.
• High Ripple Current — Handles 23.6 A at 120 Hz and 33.04 A at 100 kHz, supporting high-frequency charge/discharge and regenerative loads.
• Long Load Life — Specified for 5000 hours at 85°C under rated ripple current and DC bias, meeting endurance requirements for continuous industrial use.
• Operating Range — Rated for −40°C to +85°C ambient operation to cover a wide industrial temperature span.
• Polarized Design — Standard polarized aluminum electrolytic construction for DC bulk smoothing and energy buffering.
• Electrical Integrity — Leakage current limits after 5 minutes follow the datasheet formula (not more than 3√V µA or 5 mA whichever is smaller); insulation resistance over 100 MΩ at DC 500 V; AC 2500 V applied for 1 minute shows no abnormality.
• Compact Physical Profile — Smaller-sized LNC-series housing with dimensions L: 10.5 × D: 9 cm and a seated height of 4.134 inch for space-conscious designs.

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy storage where high voltage and sustained ripple current handling are required.
• Inverter Circuitry — DC link and smoothing capacitor for general inverter systems operating at elevated ripple currents.
• AC Servomotor Regeneration — High-frequency regenerative voltage buffering in motor drives and servo amplifiers.
• General Inverter Systems — Energy buffering and charge/discharge endurance for repeated switching cycles in inverter topologies.

Unique Advantages

• High ripple-current capability: Specified at 23.6 A (120 Hz) and 33.04 A (100 kHz), enabling reliable handling of high-frequency and regenerative currents.
• Extended endurance: 5000-hour rated load life at 85°C under applied ripple current and DC bias supports long-term continuous operation.
• Smaller-sized form factor: LNC-series compact radial can reduces space requirements while providing high-performance electrical characteristics.
• Robust electrical specifications: Defined leakage current limits, >100 MΩ insulation resistance at DC 500 V, and AC 2500 V voltage proof provide measurable electrical reliability.
• Designed for charge-discharge cycling: Meets charge-discharge endurance after 50 million cycles (ΔV = rated × 0.3, 3 Hz), supporting frequent switching environments.
• RoHS compliant: Conforms to RoHS directives (2011/65/EU, (EU)2015/863) for restricted substance compliance.
