1. Measuring condition: at 100kHz.
2. Saturation current: The value of D.C. current when the inductance decreases to 65% (while the
inductance tolerance is 30%) or 75% (while the inductance 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 ).
