※1:Measuring frequency: 2.2μH～8.2μH at 7.96MHz

10μH～1.0mH at 1kHz

※2: Rated current: The DC current at which the inductance decreases 90% of it’s initial value or when

t=40△℃, whichever is lower(Ta＝20 )℃

※3:Please give sufficient consideration to the thick wire used when mounted into the P.C.B..
