NOTES:
1. The rated current as listed is either the saturation current or the heating
current depending on which value is lower.
2. The nominal DCR tolerance is by design. The nominal DCR is measured
from point a to point b , as shown below on the mechanical drawing.
3. The saturation current is the typical current which causes the inductance
to drop by 20% at the stated ambient temperatures (25°C and 100°C).
35
30
This current is determined by placing the component in the specified
ambient environment and applying a short duration pulse current
(to eliminate self-heating effects) to the component.
4. The heating current is the DC current which causes the part temperature
to increase by approximately 40°C. This current is determined by solder-
ing the component on a typical application PCB, and then applying the
current to the device for 30 minutes without any forced air cooling.

NOTES
(continued)
:
5. 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.
To determine the approximate total losses (or temperature rise) for a
given application, the coreloss and temperature rise curves can be used.
6. Pulse complies to industry standard tape and reel specification EIA481.
7. The temperature of the component (ambient plus temperature rise) must
be within the stated operating temperature range.
