Measuring condition: at 100kHz.
※2.
Saturation current:The value of D.C. current when the inductance decreases to 65% (while the tolerance
is
±30%)
or 75% (while the tolerance is±20%) of it’s nominal.
※3.
Temperature rise current: The value of D.C. current when the temperature rise is
△t＝40℃(Ta＝20℃).
