Amorphous / Nanocrystalline Toroidal Core (Nanocrystalline Ring Core)

Precisely wound from iron-based nanocrystalline ultra-thin ribbons, available in multiple toroidal sizes. It features ultra-high initial permeability, high saturation flux density, low coercivity and low high-frequency loss, with excellent temperature stability and nearly zero magnetostriction. Compared with ferrite and permalloy, it delivers better filtering and sampling performance in a smaller size. Widely used for precision current transformers, common-mode inductors, EMC filters, photovoltaic inverters, charging piles and energy acquisition devices.
