A 50 g spool of lead-free SAC305 solder wire in a fine 0.5 mm (0.02″) diameter — ideal for both through-hole and SMT soldering work. The no-clean rosin core flux makes for clean joints without the need for post-solder cleaning.
SAC305 is a widely used RoHS-compliant lead-free formulation, making it a great alternative to traditional 60/40 leaded solder. The 50 g spool size is practical for hobbyists and makers — enough for plenty of projects without the bulk of a full 1 lb spool.
Key Features
- SAC305 Formulation – Sn 96.5%, Ag 3.0%, Cu 0.5% (tin/silver/copper)
- Lead-Free & RoHS Compliant – Safe for lead-free workshops and projects
- 0.5 mm Diameter – Fine gauge suitable for through-hole and SMT soldering
- No-Clean Rosin Core – Built-in flux for clean, reliable solder joints
- 50 g Spool – Convenient size for hobbyist and maker workbenches
Ideal For
- Electronics kit assembly and PCB soldering
- Surface-mount (SMT) component work
- Lead-free and RoHS-compliant projects
- General electronics prototyping and repair
Jargon buster
Plain-language definitions for the technical terms used above.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
