NOTES:

1. Inductance is measured at 500kHz, 100mVrms.

ambient temperatures (25°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.

2. The PA0766 consists of two separate and independent inductors inte-

grated into a single package. The two inductors can be used for two

separate phases within dual output or multi-phase application or they can

be connected in series or parallel to form a single inductor within a single

phase application.

7. 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.

3. The nominal DCR has a tolerance of 9ꢀ. 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.

8. In high volt*time applications, additional heating in the component can

occur due to core losses in the inductor which may neccessitate derat-

ing 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.

4. For manufacturing production test, a maximum DCR value of 0.9mW per

phase is used.

9. Pulse complies with industry standard tape and reel specification EIA481.

5. The rated current as listed is either the saturation current or the heating

current depending on which value is lower.

10.The temperature of the component (ambient plus temperature rise) must

be within the stated operating temperature range.

6. The saturation current is the current which causes the inductance to drop

a maximum of 26ꢀ from the nominal inductance at 0Adc at the stated
