Notes:

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

on which value is lower.

2. 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 s hort duration

pulse current (to eliminate self-heating effects) to the component.

3. The heating current is the DC current which causes the part temperature to increase by

approximately 40

°C.

4. 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 formula

can be used:

ΔB (Gauss) = K2 * ΔI

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

the stated operating temperature range.

6. Add “T” suffix to the part number for Tape & Reel version (i.e. PA2050.582NLT).
