M22759/12 wires have extruded PTFE isulation for high-temperature applications where the additional abrasion resistance of mineral-filled PTFE insulation is not required.These wires are especially well-suited in applications where smoke emission, overload stability, and flammability are major concerns. These wires are similar to M22759/9 and /10 wires, but have a thinner-wall insulation and 600V voltage rating.
