Product Description
The Wurth Elektronik 9774050243R is a precision steel round spacer designed for high-reliability surface mount technology (SMT) PCB assembly. Intended for use in demanding electronic and electromechanical systems, this spacer features a sturdy construction with a tin-plated steel body and an internal M2 thread, providing a secure and reliable mounting solution for circuit boards and components.
With a 5 mm height, the WA-SMSI series spacer achieves consistent spacing in multi-layer PCB assemblies, ensuring precise alignment and electrical isolation. The tin surface finish not only facilitates optimal soldering during automated SMT processes, but also provides excellent corrosion resistance, making it suitable for environments where performance and longevity are critical.
Designed for full automation, this round spacer significantly optimizes the assembly process of electromechanical units. The product is compliant with major environmental and safety regulations, being halogen free (compliant to both IEC 61249-2-21 and JEDEC JS709B), RoHS (2011/65/EU & 2015/863), and REACH ((EC) 1907/2006).
The Wurth Elektronik 9774050243R ensures optimal torque stability with a recommended tightening torque of 0.2 Nm. It maintains reliable operation across a broad temperature spectrum, from -55°C to +150°C. The 150-micrometer solder cream thickness makes it well-suited for controlled and repeatable soldering in mass production environments typical of industrial, medical, automotive, and telecommunications electronics.
Typical use cases include supporting PCB hardware in densely packed control panels, ensuring component clearance in high-density electronics, and providing robust, corrosion-resistant standoffs in professional electronic device manufacturing lines.
