LNC2V183MSEJ

The LNC2V183MSEJ is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNC series, rated 18,000 µF at 350 V. Designed for high‑power industrial applications, it targets inverter circuitry, regenerative drives and other high‑frequency power conversion systems that require high ripple handling and dependable endurance.

Its screw‑terminal radial can construction and compact form factor deliver high ripple current capability and support high‑speed charge/discharge loading while meeting a 5000‑hour load‑life rating at 85°C. The part is RoHS compliant.

Key Features

• High capacitance: 18,000 µF (18 mF) nominal capacitance for bulk energy storage and smoothing in power conversion applications.
• 350 V rated voltage: Rated voltage of 350 V for high‑voltage inverter and regenerative circuits.
• Screw‑terminal radial can: Robust screw‑terminal mounting and radial can package (φ90×165 mm) for secure, low‑impedance high‑current connections.
• High ripple current capability: Specified ripple current of 39.2 A at 120 Hz and 54.88 A at 100 kHz to support high‑frequency and high‑current operation.
• Extended load life: Endurance specified as 5000 hours with D.C. bias plus rated ripple current at 85°C, with defined post‑test limits for capacitance, tan δ and leakage current.
• Wide operating temperature: Operates from −40°C to +85°C for use across industrial temperature ranges.
• Polarized device with controlled leakage: Polarized aluminum electrolytic construction; leakage current after 5 minutes is limited to 3√V (µA) or 5 mA, whichever is smaller (at 20°C), per datasheet.
• Endurance and charge‑discharge robustness: Capable of enduring charge‑discharge endurance testing (50 million cycles, ΔV = 0.3×rated voltage at 3 Hz) with specified limits on capacitance, tan δ and leakage.
• Electrical safety margins: Insulation resistance >100 MΩ at DC 500 V between terminal and bracket, and voltage‑proof test AC 2500 V for 1 minute between terminal and bracket.
• RoHS compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies: Bulk energy storage and smoothing for inverter front‑ends and DC link circuits in industrial power supplies.
• AC servomotor regenerative circuits: Handling high‑frequency regenerative voltage and absorbing returned energy in servo drives.
• General inverters and motor drives: High ripple and high‑current filtering for inverter output stages and motor drive systems.
• High‑speed charge/discharge systems: Applications requiring frequent or rapid charge‑discharge cycles where endurance under repeated cycling is required.

Unique Advantages

• High ripple handling: Rated ripple currents up to 54.88 A at 100 kHz reduce stress on DC link filtering in high‑frequency converters.
• Compact screw‑terminal packaging: φ90×165 mm radial can with screw terminals provides a secure, low‑impedance connection suited for high‑current assemblies.
• Specified 5000‑hour load life: Endurance rating at 85°C with defined post‑test performance criteria supports long‑term stability in continuous‑duty power systems.
• Wide temperature range: −40°C to +85°C operation keeps performance predictable across industrial ambient conditions.
• Charge‑discharge endurance: Proven to withstand extensive charge/discharge cycling (50 million cycles at specified test conditions), supporting applications with heavy dynamic loading.
• Compliance and safety margins: RoHS compliance, high insulation resistance and voltage‑proof test values deliver clear, testable electrical safety characteristics.
