Tolerance of inductance: 30% |
for 1.7~6.8uH; 20% |
for 10~33uH. |
2. |
Isat is the DC current which |
cause the inductance |
drop 35% typical 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). |
