Kester 24-6040-0039 Rosin Core Solder Roll, 0.040 inch Diameter, Sn60Pb40, 44 Flux Activated, 1 lb

Kester 24-6040-0039 Rosin Core Solder Roll

Discover a trusted flux-cored solution designed for general electronics soldering. The Kester 44 rosin flux is an activated rosin formulation known for its strong wetting characteristics and steady performance across a range of components. This product ships as a 1 lb spool, providing a consistent feed for both prototyping and mid-volume production.

Made with leaded Sn60Pb40 alloy, this solder wire uses a 0.040 inch (1.00 mm) diameter for versatile use on medium to large wires and components. The flux core carries about 3.3% flux content, delivering activity that supports reliable joints while balancing residue management.

Key benefits at a glance

• Instant-action wetting and high mobility may help you achieve smooth joints more quickly.
• Fast-spreading flux core can improve joint coverage on densely packed assemblies.
• Leaded Sn60Pb40 alloy with rosin core for general purpose soldering tasks.
• One pound per spool suits ongoing projects, repairs, and light-to-mid volume work.

What to expect in real-world use

• Rosin flux with long-standing industry use, compatible with standard cleaning procedures.
• 0.040 in diameter is a practical choice for mid-size wires and common surface mount or through-hole components.
• Flux content of 3.3% provides a balance between activity and cleanability, helping produced joints feel ready for inspection.
