Saturation Current 3
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).
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 soldering the component on a
typical application PCB, and then applying the current to the device for 30 minutes
without any forced air cooling.
5. In high volt*time applications, additional heating in the component can occur due to
core losses in the inductor which may necessitate 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
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.
8. For part marking only the PA0513 series has the name ‘Pulse’ marked on the part.
Due to component size, the remaining series’ of parts are marked only with the Pulse PN,
Date Code and Country of Origin.
