NOTES:
1. The nominal DCR has a tolerance of ±6%. This tolerance is guaranteed by design,
but is not a manufacturing production test. The nominal DCR is measured from point
a to point b , as shown below on the mechanical drawing.
2. For manufacturing production test, a maximum DCR value of 0.5mΩ is used.
3. The inductance has a tolerance of ±9%. This tolerance is guaranteed by design, but
is not a manufacturing production test. For manufacturing production test, a toler-
ance of ±20% is used.
4. The rated current as listed is either the saturation current or the heating current
depending on which value is lower.
5. The saturation current is the current which causes the inductance to drop by 20% at
the stated ambient temperatures (25°C and 100°C). 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.
6. The heating current is the DC current which causes the part temperature to increase
by approximately 40°C. This current is determined by soldering the component on a
typical application PCB, and then applying the current to the device for 30 minutes
without any forced air cooling.
7. 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.
8. Pulse complies with industry standard tape and reel specification EIA481.
