Add the tolerance of inductance to within the h of the part Number as follows: J=5%, K=10% h J=5%, K=10%
(1)Inductance is measured with a LCR meter 4194A () or 4291A () (2)DC resistance is measured with a Digital Multimeter TR6871 (Advantest) or equivalent. (3)Maximum allowable DC current is that which causes a 10% inductance reduction from the initial value, or coil temperature to rise by 20C, whichever is smaller. (Reference ambient temperature 20C)
