※1. Inductance 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℃).
