1. Open Circuit Inductance Test Parameters: 100kHz, 0.25V, 0.0Adc. 

2. Inecessary for AC currents. PCB layout, trace thickness and width, air-flow, rms: DC current for an approximate ∆T of 40°C without core loss. Derating is and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed 125°C under worst case operating conditions verified in the end application. 

   4. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K*L*∆I, Bp-p (mT), K: (K factor from table), L: (Inductance in μH), 

   - ∆I (Peak to peak ripple current in Amps). 

   5. Part Number Definition: DR124-xxx-R 

   - DR124 = Product code and size; -xxx = Inductance value in uH; 

   - R = decimal point; If no R is present, third character = # of zeros. 

   - “-R” suffix = RoHS compliant 

3. Isat Amps peak for approximately 25% rolloff (@25°C).
