CURRENT (A) |
|
|
1. |
Tolerance of inductance : 15% for 1.2~4.7uH, 10% for 10~1000uH. |
2. |
Irated is the DC current which cause the inductance drop less than 10% of its nominal inductance without current |
|
and the surface temperature of the part increase less than 45oC. |
3. |
Operating temperature: -20oC to 105oC (including self-temperature rise). |
