(2) The rated current is the approximate DC current at which T is approximately 60C. This current is determined by soldering (3) Isat is the saturation current at which inductance rolls off approximately 30% from its initial unbias inductance value. the unit on a typical application PCB, and then applying the current to the unit for 30 minutes. * Low cost version We reserve the right to change specifications without prior notice.
