Kester 24-9574-1406 Solder Wire - SN99.3 Rosin Core Lead, 0.043" Diameter, 33.3 ft.
Description:The Kester 24-9574-1406 solder wire is a high-performance rosin core lead designed for use in various electronic assembly applications. This solder wire, with a Sn99.3 composition, is made up of 99.3% tin and 0.7% copper, making it an excellent choice for applications requiring a high degree of tin content.
This specific solder wire has a diameter of 0.043 inches (1.1 mm), which is suitable for a wide range of through-hole and termination soldering applications. With a length of 33.3 feet (10.1 meters), a single spool provides ample material for most projects, reducing the need for frequent reloads.
The rosin core of this solder wire plays a crucial role in its performance. Rosin is a naturally occurring organic substance that creates a flux coating on the wire as it is melted and flows through the soldering process. This flux helps clean the metal surfaces, removing oxides and other contaminants, and ensures a strong, reliable joint.
The Kester 24-9574-1406 solder wire undergoes rigorous testing to ensure its consistency and quality. It is RoHS compliant and meets the requirements of J-STD-001, ensuring it meets industry standards and can be used in a wide range of applications.
In summary, the Kester 24-9574-1406 solder wire offers a high tin content, suitable diameter, and rosin core flux, making it an excellent choice for various electronic assembly applications. Its RoHS compliance and J-STD-001 certification ensure its reliability and compatibility with industry standards.
