NOTES:

1. Inductance measured at 100kHz, 100mVrms.

2. Inductance at Irated is the value of the inductance at 25°C at the listed rated current.

3. The rated current as listed is either the saturation current (25°C or 100°C) or the heating current depending on

which value is lower.

4. The nominal DCR is measured from point a to point b , as shown below on the mechanical drawing.

5. The saturation current is the typical current which causes the inductance to drop by 20% at the stated ambient

temperatures (25°C, 100°C and 125°C). This current is determined by placing the component in the specified ambi-

ent 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 when used in a typical application.

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 deter-

mine the approximate total losses (or temperature rise) for a given application, the coreloss and temperature

rise curves can be used.

8. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e. PA3779.141HL

becomes PA3779.141HLT).

Pulse complies to industry standard tape and reel specification EIA481. The tape and reel for this product has a

width (W=24mm), pitch (Po=12.0mm) and depth (Ko=8.7mm).

9. The temperature of the component (ambient plus temperature rise) must be within the stated operating tem-

perature range.
