LNK2G183MSEJ

The LNK2G183MSEJ is a screw-terminal, smaller-sized aluminum electrolytic capacitor offering 18,000 µF capacitance at a 400 V rating. It is a polarized radial can designed for general-purpose applications that require high capacitance, high ripple-current capability and robust long-term endurance.

Key value propositions include high ripple-current handling, a long 5,000-hour load-life at 85°C, and RoHS compliance—making it suitable where sustained high-voltage energy storage and reliable terminal connections are required.

Key Features

• Capacitance — 18,000 µF nominal capacitance for substantial bulk energy storage in power circuits.
• Rated Voltage — 400 V DC rating for high-voltage system applications within the product’s specification.
• High ripple-current capability — Rated ripple current of 41.2 A at 120 Hz and 57.68 A at 10 kHz, supporting heavy AC ripple conditions.
• Endurance and reliability — Load-life specified at 5,000 hours with rated ripple current at 85°C, with capacitance change within ±20% after the endurance test when restored to 20°C.
• Temperature range — Operates from −25°C to +85°C to cover a wide range of ambient conditions.
• Construction and mounting — Screw-terminal radial can package for secure mechanical and electrical connections; polarized design.
• Leakage and insulation — Leakage current limited to 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at 20°C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Compliance — RoHS compliant.
• Physical footprint — Smaller-sized radial can with dimensions listed as L: 23.5 × D: 9 cm (see datasheet for mounting and bracket details).

Typical Applications

• General-purpose power systems — Provides bulk energy storage and smoothing where high capacitance at 400 V and high ripple-current capability are required.
• High-voltage DC circuits — Suited for applications that need a polarized electrolytic capacitor rated to 400 V with defined endurance at elevated temperatures.
• Environments requiring secure termination — Screw-terminal mounting supports robust electrical and mechanical connections in assemblies needing reliable terminals.

Unique Advantages

• Large capacitance in a smaller package — 18,000 µF provides significant energy storage while the series is described as smaller-sized, facilitating space-efficient designs.
• High ripple-current handling — Specified ripple currents (41.2 A at 120 Hz; 57.68 A at 10 kHz) reduce heating and support sustained AC stress in power-conversion circuits.
• Proven endurance — 5,000-hour load-life at 85°C under rated ripple current gives predictable aging characteristics for long-term designs.
• Robust electrical isolation — Insulation resistance >100 MΩ at DC 500 V and a voltage proof of AC 2,500 V for 1 minute between terminal and bracket enhance safety margins for high-voltage assemblies.
• Screw-terminal convenience — Facilitates secure, low-resistance connections and easier field installation or replacement compared with soldered terminals.
• Regulatory compatibility — RoHS compliance supports use in assemblies requiring restricted-substance adherence.
