High Initial Permeability Nanocrystalline Core

High Initial Permeability Nanocrystalline Core

Similar to permalloy, our nanocrystalline cores have high initial permeability, but the price is much lower, as the material is based on iron. Due to excellent magnetic properties, our cores are widely used for miniature current transformers, inductors, and so on. With more than 15 years experience, we can design and manufacture customized cores, and provide samples with a couple of days.
