(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)
