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 25C TT Electronics BI Technologies General Note A-1445, Jalan Tanjung Api, TT Electronics reserves the right to make changes in product specificaoti n without 25050 Kuantan, Pahang Darul Makmur, Malaysia nocti e or liability.
