AMCC Series Bobbins

Miles Platts’ amorphous metal core coil (AMCC) bobbins are specifically designed and manufactured for amorphous metal C-core style, typically used in high efficiency, medium frequency power conversion applications. 
These AMCC bobbins are available in 18 sizes from C4 to C320, in glass-filled, engineering PET polymer (>PET-GF30FR<) providing UL94V0 flammability rating, Class N +200°C isolation class.

Miles Platts’ AMMC bobbins are precision injection molded with a robust mechanical structure to ensure efficient winding of the coil, guaranteeing a high quality and repeatable finish. This robust structure also guarantees a high level of electrical isolation (35 kV/mm) between the core and the magnet wire.

Amorphous metal cores are typically made from metallic alloys like iron or nickel and are described as non-crystalline materials with irregular atomic structures. While operating, they generate less heat, ensuring increased efficiency due to their lower core loss. Using tape-wound amorphous metal alloys increases electrical conductivity and improves magnetic density, optimizing overall performance.

This type of core is compatible with Miles Platts’ AMCC bobbins as they are designed for use with single-phase tape wound cut C-cores available from several core manufacturers. The combination of amorphous alloy cores and Miles Platts’ AMCC bobbins provides higher permeability, resulting in a smaller and more energy-efficient design than traditional materials.
