LNK2W123MSEJ

The LNK2W123MSEJ from Nichicon is a smaller-sized aluminum electrolytic capacitor in the LNK series designed with screw-terminal mounting for robust electrical and mechanical connections. It provides 12,000 µF capacitance at a 450 V rating and is intended for general-purpose applications where high voltage handling, high ripple current capability, and long operational life are required.

Key value propositions include high ripple-current capability at both low and high frequencies, a rated operating temperature range to 85°C, extended load life under rated ripple conditions, and RoHS compliance.

Key Features

• Capacitance & Voltage — 12,000 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, supporting high-voltage bulk energy storage.
• High Ripple Current — Rated ripple current of 29.7 A at 120 Hz and 41.58 A at 10 kHz, providing strong performance for ripple-loading environments.
• Thermal & Lifetime Performance — Rated for operation from −25 °C to +85 °C with a specified load life of 5,000 hours at 85 °C when subjected to DC bias plus rated ripple current.
• Robust Endurance — After endurance testing (DC bias plus rated ripple current for 5,000 hours at 85 °C), specified parameters return to within the defined limits (capacitance change within ±20% of initial value).
• Mounting & Package — Screw terminal radial can package for secure, serviceable connections and mechanical stability in high-current applications.
• Safety & Insulation — Insulation resistance greater than 100 MΩ when tested at DC 500 V between terminal and bracket; voltage-proof tested at AC 2500 V for 1 minute between terminal and bracket.
• RoHS Compliant — Manufactured to meet RoHS directive requirements.

Typical Applications

• General-purpose power systems — Designed for general-purpose applications that require 12,000 µF capacitance at 450 V with screw-terminal mounting for reliable connections.
• High-ripple environments — Suited to systems where elevated ripple currents are present, leveraging the specified ripple current ratings at 120 Hz and 10 kHz.
• Thermally constrained designs — Intended for use in applications operating within −25 °C to +85 °C and requiring components with a defined 5,000-hour load life at 85 °C.

Unique Advantages

• High-voltage capability: 450 V rating supports higher DC bus voltages without additional component stacking.
• High ripple-current handling: Defined ripple current values at both 120 Hz and 10 kHz allow specification against real-world AC and switching ripple loads.
• Long rated life under load: 5,000 hours at 85 °C under rated ripple current provides predictable endurance for maintenance planning.
• Serviceable screw-terminal mounting: Screw terminals enable robust, repeatable electrical connections and simplify installation or replacement in the field.
• Verified insulation and voltage proof: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V/1 min voltage-proof testing between terminal and bracket enhance reliability in high-voltage systems.
• Regulatory compliance: RoHS compliance supports use in regions and projects requiring restricted-substance conformance.
