Tolerance of inductance : ± 15% for 0.22~8.2uH, ± 10% for 10~100uH
Isat is the DC current which cause the inductance drop less than 10% of it’s nominal inductance without current.
Ir is the DC current which cause the surface temperature of the part increase less than 45 ℃.
Operating temperature: -40℃ to 125℃ (Self-temperature rise included).
