1. Tolerance of inductance: 30% for 1.0~4.7uH, 20% for 6.8~47uH.
2. Isat is the DC current which cause the inductance drop 30% typical of its nominal inductance without current.
o
3. Ir is the DC current which cause the surface temperature of the part increase less than 40 C.
o
4. Rated current : Value obtained when current flows and the temperature has risen to 40 C or when DC current
flows and the nominal value of inductance has fallen by 30%, whichever is smaller.
oo
5. Operating temperature: -40 C to 125 C (including self-temperature rise).
