Miles Platts AMCC coil bobbins are specifically designed and manufactured for amorphous metal C-core style which are typically used in high efficiency, medium frequency power conversion applications.

Our amorphous metal core coil bobbins, also known as AMCC bobbins are available in 18 sizes from C4-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 moulded with a robust mechanical structure to ensure efficient winding of the coil to guarantee a high quality and repeatable finish. This robust structure also guarantees a high level of electrical isolation (35kV/mm) between the core and the magnet wire.

Typical AMCC bobbin applications include:

• Grid power and distribution transformers
• EV charging
• Telecommunications power
• Aviation
• Rail applications

What are amorphous metal cores?

Amorphous metal cores are typically made from metallic alloys like iron or nickel and are described as non-crystalline materials which have an irregular atomic structure. While operating they generate less heat ensuring increased efficiency due to their lower core loss. By using tape-wound amorphous metal alloys, electrical conductivity is increased while also improving 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 which ultimately results in a smaller and more energy-efficient design when compared to traditional materials.
