Part No:High BS low loss factor MnZn material ferrite coreApplication information :PCB board, power swich, car component,heater,and other need transformer equipments.General instruction:UY cores such as UY16, are kind of MnZn alloy core, which can as EMI bead core rod core,coil cores,SM core,tape wind magnetic core. Round leg allows easy winding ,also of strip conductors,because of the high voltage involved,the round shape helps to prevent corona effect, High saturation magnetic flux density.Bobbin:Vertical,horizontal.Size:UY12,UY12.5,UY13.
