注Note：① The values were obtained with toroidal cores at room temerature unless otherwise shown.
② JR2KBF、JR2KBF 1 and JR2KBF 2 are the same as the PC30,PC40,PC44 materials. JR2KBH、JR2KBF 2 JR2KBF、JR2KBF,JR2KBF 2 are the same as the HV22,HV45 materials.
JRXXS Series is high μi and high impedance material.
