Winding wire:
Enameled copper wire – low losses, good solderability, high reliability; standard for most applications
CCA wire
(Copper Clad Aluminum) – lighter weight and lower material costs; higher resistance than copper
Insulation / Varnish System
Polyester, polyurethane, or polyamideimide – depending on temperature class, dielectric strength, and chemical exposure
Coil formers
polyamide, PBT, or other temperature-resistant insulating materials; ceramics and high-performance plastics for special applications
Every application has its own requirements. The following parameters are specifically designed to meet your specifications:
