260°C Maximum reflow temperature per J-STD020
Schematic Diagram
Notes:
Inductance measured at 100kHz, 100mVrms at 20°C.
DCR (DC resistance) are maximum @ 20°C.
Irms is the current applied to produce a typical 30°C
temperaturer rise from nominal inductance.
Isat is a maximum applied AC + DC current.
Isat is the current applied to produce a typipcal 10% drop
in nominal inductance
Tolerance suffix of M = ±20%.
