1. Tolerance of inductance: 20% for 1.0~220.0uH.
2. Isat is the DC current which cause the inductance drop 30% typical of its nominal inductance without current.
3. Ir is the DC current which cause the surface temperature of the part increase less than 40
o
C.
4. Rated current : Value obtained when current flows and the temperature has risen to 40
o
C or when DC current
flows and the nominal value of inductance has fallen by 30%, whichever is smaller.
5. Operating temperature: -40
o
C to 125
