    The latest issued in the wide temperature range showed low loss characteristics of the vehicle with the soft ferrite magnetic core material, and the establishment of a production system. The material is expected to be used in automotive electronic devices such as transformers and inductors to achieve higher efficiency and reliability, and become smaller and lighter.
     
    Automotive electronic components will also be used near the engine room, so car manufacturers want to improve their performance and reliability over a wider range of temperatures. The core components such as transformers and inductors using magnetic field occurs loss, this loss of energy will be converted into heat, causing the surrounding temperature rise, therefore, manufacturers need to develop in a high temperature environment is also very low core loss material.
    Mn Zn ferrite (Mn-Zn) material, the ratio of powder technology and heat treatment technology and the latest development. The core loss is reduced by more than 15% and the saturation magnetic flux density is increased by more than 20% under the condition of high temperature of 140 DEG C. Curie temperature is 250 degrees.
