(1) Inductance is measured with a a |Z| Analyzer 4291A/ B (Agilent
Technologies) or equivalent. Test frequency at 1MHz, 0.5V
(2) DC Resistance is measured with a milliohmmeter 4338B (Agilent
Technologies) or equivalent.
(3) Maximum allowable DC current is that causes coil temperature to
rise by 40°C .ç (The ambient reference temperature:20°C)
