Nanocrystalline cores are a choice solution for applications such as common mode chokes and current transformers as they exhibit high permeability, low power loss, and high saturation. Nanocrystalline cores are a lower cost alternative to permalloy and exhibit improved accuracy compared to silicon steel. The material’s low AC losses result in excellent efficiency, and the option of durable cases - available in polyester (<130°C) and rynite polyester (<155°C) - makes cores suitable for winding with thick wire.

Available in toroids and split cores from 5 mm to 145 mm, Magnetics’ nanocrystalline cores can also be used in switched-mode power supplies (SMPS), uninterruptible power supplies (UPS), solar inverters, frequency converters, EMC filters, and automotive and welding applications.
