(1) Inductance is measured with a LCR meter 4284A (Agilent Technologies)

or equivalent.

Test frequency at 100kHz

(2) DC resistance is measured with a Digital Multimeter TR6871 (Advantest)

or equivalent.

(3) Maximum allowable DC current is that which causes a 10% inductance

reduction from the initial value, or coil temperature to rise by 40°C

whichever is smaller.(Reference ambient temperature: 20°C)
