LNK2W182MSEFBN

The LNK2W182MSEFBN is an aluminum electrolytic capacitor in a screw terminal radial can package designed for general-purpose high-voltage applications. It provides 1800 µF capacitance at a 450 V rating with a smaller-sized footprint and screw terminals for robust electrical and mechanical connection.

Designed for use where high ripple-handling and long operational life are required, this part combines high-voltage capability, elevated ripple current ratings across frequency, and a 5000-hour load-life specification at 85°C.

Key Features

• Electrical Rating — 1800 µF capacitance at 450 V rated voltage with polarization suitable for DC applications; capacitance tolerance ±20%.
• High Ripple Current — Rated ripple current of 7.6 A at 120 Hz and 10.64 A at 100 kHz, supporting applications with significant AC on DC conditions.
• Endurance and Reliability — Load life specified at 5000 hours at 85°C with D.C. bias plus rated ripple current; capacitance change within ±20% after recovery to 20°C.
• Operating Temperature Range — Specified for −25°C to +85°C operation to cover a broad range of ambient conditions.
• Leakage and Insulation — Leakage current after 5 minutes is limited to 3√CV (µA) or 5 mA, whichever is smaller (at 20°C); insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• High Voltage Proof — Withstands AC 2500 V for 1 minute between terminal and bracket with no abnormality.
• Package & Mounting — Radial can with screw terminals for secure bolted connections; physical size L: 10.5 × D: 5.1 cm and seated height max 4.134 inch.
• RoHS Compliant — Meets RoHS directive requirements as stated in the product information.

Typical Applications

• General-purpose power filtering — Suitable for circuits that require 450 V DC bulk capacitance and high ripple handling in a screw-terminal package.
• High-voltage DC bus or energy storage — Provides bulk energy storage and smoothing where a 1800 µF, 450 V polarized capacitor is specified.
• Industrial and power modules — Screw-terminal construction enables secure mechanical and electrical connection in rack-mounted or modular power assemblies.

Unique Advantages

• High ripple capability: Rated ripple currents at both low and high frequencies reduce thermal stress in applications with significant AC content on DC rails.
• Long operational life: 5000 hours at 85°C with rated ripple current provides predictable end-of-life behavior for maintenance planning.
• Robust screw-terminal mounting: Facilitates reliable bolted connections and straightforward installation or replacement in field serviceable systems.
• High-voltage rating: 450 V rating supports designs requiring elevated DC voltages without additional series stacking.
• Clear recovery and reliability metrics: Endurance and leakage current specifications tied to standardized test conditions allow straightforward verification during qualification.
• Regulatory compliance: RoHS compliance supports use in products where restricted substance directives are required.
