Specifications @ 25°C

Notes:

(1) Inductance is measured at 100kHz, 0.1Vrms

(2) The Heating Current is the DC current which causes the component 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

(3) The saturation current (Isat) is the approximate current at which the inductance will be decreased by 20% typical from

its initial (zero DC) value

(4) DCR is measured at room temperature 25°C
