NOTES:
1. The rated current as listed is either 85% of the saturation current or the heating current, depending on which value is lower.
2. The saturation current is the current which causes the inductance to drop by 15% at the stated ambient temperatures (25擄C and 100擄C). This current is determined by
lacing the component in the specified ambient environment and applying a short duration pulse current (to eliminate self-heating effects) to the component.
3. The heating current is the dc current which causes the temperature of the part to increase by approximately 45擄C. This current is determined by mounting the component
on a PCB with .25鈥?wide, 2 oz. equivalent copper traces, and applying the current to the device for 30 minutes with no forced air cooling.
4. In high volt*time applications, additional heating in the component can occur due to core losses in the inductor which may neccessitate derating the current in order
to limit the temperature rise of the component. In order to determine the approximate total losses (or temperature rise) for a given
application, the total copper and core losses should be taken into account. For approximate value of core losses, in a given application, use the core loss graph on page 4.
5. Pulse recommends the followng solderability test: Dip pin tip in flux (mildly active), dip in solder pot (63Sn/37Pb solder) at 245擄C for 5 seconds.
