1) Test Parameters: 100KHz, 1.0Vrms

2) Irms Amperes for approximately

∆T of 40°C above 85°C ambient

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).

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

case operating conditions verified in the end application.
