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 10% inductance reduction from the initial value, or coil temperature to rise by 40°C,
whichever is smaller. (Reference ambient temperature 20°C).
