Notes:<br />
1 - The rated current is the saturation current @ 25oC. 2 - The I(Saturation) is the current at which the inductance drops by 20% maximum of its value at 0ADC. This current is measured at the<br />
stated ambient environment and by applying a short duration pulse current to the component, minimizing the self-heating effects.<br />
3 - The I(Temp. Rise) is the current at which the temperature of the part increases by a maximum of 50oC. This test is per<strong>for</strong>med with the<br />
part mounted on a PCB with 0.250" wide, 0.004" thick copper traces and applying the DC current <strong>for</strong> a minimum of 30 minutes.<br />
4 - Inductance is measured at 100 KHz and 1.0 Vrms.<br />
5 - The additional Temperature Rise due to <strong>High</strong> ET (Voltage x Time) can be estimated using the following <strong>for</strong>mula:<br />
DCR Loss = Idc2 Trise (<br />

I = Delta I across the inductor<br />
F = Switching <strong>Frequency</strong> (kHz)<br />
