Tolerance of inductance: 15% for 1.0~8.2uH, 10% for 10~100uH. 2. Isat is the DC current which cause the inductance drop less than 10% of its nominal inductance without current. 3. Ir is the DC current which cause the surface temperature of the part increase less than 45oC. 4. Operating temperature : -20oC to 105oC (including self-temperature rise). DELTA ELECTRONICS, INC.
