Ultra Fine 0.03mm Enameled Copper Magnet Wire For Earphones
For winding custom coils, or very fine-pitch rework, we always reach for magnet wire. Magnet wire is very very thin copper wire with a very thin layer of insulation. It's used for a range of electronics, hacking and making applications. Commonly these are used for winding transformers, inductors, motor or solenoid coils, speakers, hard disk head actuators, electromagnets, pickups, among other things. However, this wire is also really good for when you have to do PCB repair, jumper wires, or solder directly to SMT pads.
