IMPEDER CORES FOR
HIGH FREQUENCY WELDING
TDK has introduced IPH2 material, which has lower reluctance than the original IPH material at higher temperatures. IPH2 material is tuned to have lower loss closer to the application temperature. It has a slightly higher saturation flux density than the well-accepted IPH material currently in use in the industry.
IPH2 material will also allow using an extended range of frequency compared to IPH material in welding applications. As a result of these improved features, IPH2 material will further improve the efficiency of the welding process.
TDK materials properties
Measurements are based on a toroidal core.
