1) Open Circuit Inductance test parameters: 100KHz, 1.0V, 0.0Adc

2) Irms: DC current for an approximate DT of 40°C without core loss. Derating is

necessary for AC currents. PCB layout, trace thickness and width, air-flow, and

proximity of other heat generating components will affect the temperature rise. It is

recommended that the temperature of the part not exceed 155°C under worst case

operating conditions verified in the end application.

3) Isat Amperes Peak for approximately 15% rolloff (@20°C)

4) Isat Amperes Peak for approximately 30% rolloff (@20°C)

5) Applied Volt-Time product (V-µS) across the inductor. This value represents the

applied V-µS at operating frequency necessary to generate additional core loss

which contributes to the 40°C temperature rise. De-rating of the Irms is required

to prevent excessive temperature rise. The 100% V-uS rating is equivalent to a

ripple current Ip-p of 20% of Isat (30% rolloff option).
