Amorphous magnetic sheet
This iron‑based amorphous magnetic sheet is an exclusive upgrade component for common‑mode inductors, designed to directly replace conventional PBT insulating spacers. It transforms a single‑layer insulation structure into an integrated composite architecture that combines electrical isolation, high‑frequency magnetic shielding, and optimized magnetic circuitry. While fully complying with safety standards for insulation, creepage distance, and dielectric strength, it enhances the common‑mode inductor’s electromagnetic performance, thermal management, and structural reliability, making it ideally suited for high‑frequency, high‑power, and high‑density industrial and automotive power‑supply applications. It represents a core upgrade solution for optimizing EMI filtering in premium power supplies.

Amorphous magnetic sheet
The core advantage of using an amorphous magnetic sheet to replace the PBT (or similar insulating material) separator between the two windings of a common-mode inductor’s magnetic core.
First, let’s clarify the structure: In a conventional common-mode choke with magnetic cores, the two windings are separated by a PBT plastic spacer. By replacing this with amorphous (iron‑based amorphous) thin magnetic sheets sandwiched between the windings, we essentially upgrade the insulating spacer into a composite component that provides “insulation + magnetic shielding + magnetic optimization.” The key advantages lie in… Stronger common-mode rejection, lower leakage inductance, reduced temperature rise, improved EMI performance, and a smaller footprint. 。
(1) Enhance electromagnetic performance and optimize EMI filtering effectiveness.
(2) Low losses and low temperature rise, enhancing equipment stability and service life.
(3) Structural Upgrading: Balancing Miniaturization and Reliability
(4) Comprehensive cost optimization for greater value.
