LNK2W182MSEGBB

The LNK2W182MSEGBB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose applications. It delivers 1.8 mF (1800 µF) capacitance at a 450 V rating, with polarized construction and screw-terminal mounting for secure high-current connections.

Engineered for sustained operation up to 85°C, this part offers a specified load life of 5000 hours at 85°C under rated ripple current and is RoHS compliant, making it suitable for designs that require high-voltage bulk capacitance with reliable long-term performance.

Key Features

• High-capacitance / High-voltage: 1.8 mF (1800 µF) rated at 450 V for applications requiring substantial energy storage at elevated voltages.
• Screw-terminal mounting: Radial can with screw terminals provides robust mechanical and electrical connection for high-current and serviceable installations.
• Rated ripple current: Handles 7.6 A at 120 Hz and 10.64 A at 10 kHz, supporting applications with significant AC ripple demands.
• Temperature and lifetime: Operates from −25°C to +85°C with a load-life rating of 5000 hours at 85°C when subjected to DC bias plus rated ripple current.
• Endurance and reliability: After the specified endurance test (5000 hours at 85°C with rated ripple), capacitance change remains within ±20%, ESR remains ≤300% of initial, and leakage current stays within initial specified limits.
• Leakage current specification: After 5 minutes at rated voltage and 20°C, leakage current does not exceed 3√(C·V) μA or 5 mA, whichever is smaller (C = μF, V = V).
• Physical footprint: Package dimensions L: 8.5 × D: 6.35 cm with a maximum seated height of 3.346 inches, suitable for assemblies that accept a radial can with screw terminals.
• Compliance: RoHS compliant per 2011/65/EU and (EU)2015/863.
• Tolerance and polarity: Capacitance tolerance ±20% and polarized construction—observe correct polarity in application.

Typical Applications

• Industrial power supplies — Provides high-voltage bulk capacitance for energy storage and smoothing where 450 V, 1800 µF values are required.
• Power electronics assemblies — Screw-terminal mounting enables secure connections in high-current power stacks and serviceable modules.
• General-purpose high-voltage circuits — Suitable for systems needing a polarized aluminum electrolytic with defined endurance at 85°C.

Unique Advantages

• High-voltage, high-capacitance combination: 1.8 mF at 450 V provides substantial stored energy per component, reducing the number of parallel devices required.
• Robust screw-terminal interface: Ensures reliable mechanical fastening and low-resistance connections for high ripple currents and repeated service.
• Specified endurance at elevated temperature: 5000-hour load life at 85°C under rated ripple current gives designers measurable long-term performance expectations.
• Quantified ripple handling: Published ripple current ratings at 120 Hz and 10 kHz allow precise thermal and stress calculations in design validation.
• Clear leakage and endurance limits: Defined leakage current formula and post-endurance limits for capacitance and ESR support predictable maintenance intervals and reliability planning.
• Regulatory compliance: RoHS conformity supports deployment in regions requiring restricted-substance compliance.
