(1) Inductance is measured with a LCR meter 4284A* 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 30% inductance reduction from the initial value, coil temperature to rise by 40°C, whichever is smaller. (Reference ambient temperature 20°C)
