(1) Inductance is measured with a LCR meter 4284A (Agilent
Technologies) or equival ent.
Test frequenc y at 100kHz
(2)
DC resistanc e is measured with 34420A (Agilent Technologi es) or
3541(HIOKI). (Reference ambient temperature 25°C)
(3)
Maximum allowable DC current is that which causes a 30%
inductance reducti on from the initial value, or coil temperature to
rise by 40°C, whichever is smaller. (Reference ambient
temperature 20° C)
