STANDARD PARTS SELECTION GUIDE

(1) Inductance is measured by LCR-meter 4284A (Agilent) or equivalent.

(2) DC resistance is measured by Digital Multimeter TR6871 (Advantest) or equivalent.

(3) Maximum allowable DC current is that which causes a 30% inductance reduction from the initial value,

or coil temperature to rise by 40°C, whichever is smaller. (Reference ambient temperature 20°C).

Rated DC current for a 10% inductance reduction is provided as well.
