Dongguan JH Amorphous offers high-performance nanocrystalline cores specifically designed for common mode chokes (CMC), which are used to suppress electromagnetic interference (EMI) and ensure compliance with EMC standards. These cores are made from Fe–Cu–Nb–Si–B nanocrystalline soft magnetic alloys, featuring ultra-fine grain structures (12–25 μm) that provide exceptional magnetic properties. They are ideal for use in power electronics such as inverters, switching power supplies, and EMI filters, contributing to improved energy efficiency, reduced system size, and enhanced thermal stability in electrical systems.
With a high initial permeability (μi = 80,000) and a high level of permeability, these cores allow for achieving higher inductance with fewer turns, reducing coil size and copper losses. This results in a smaller volume, higher impedance, and lower winding capacity, making them an ideal choice for compact and efficient common mode chokes.
