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 is measured from point a to point b , as shown on the mechanical

drawing below.

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 e ects) 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.

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

be used.

6. Optional tape and reel packaging can be ordered by adding a “T” su x to the part

number (i.e. PA2509.121NL becomes PA2509.121NLT). Pulse complies to industry

standard tape and reel specification EIA481. The tape and reel for this product has a

width (W=24mm), pitch (Po=16.0mm) and depth (Ko=8.9mm).

7. The temperature of the component (ambient plus temperature rise) must be within the

stated operating temperature range.
