INDUCTANCE (uH)
1. Tolerance of inductance: 30% for 10~82uH, 20% for 100~820uH, 10% for 1000~3900uH.
2. Irated is the DC current which cause the inductance drop 10% typical of its nominal inductance without current
and the surface temperature of the part increase less than 45
o
C.
3. Operating temperature : -20
o
C to 105
o
C (including self-temperature rise).
