(2) maximum allowable dc current is that which causes a 10% inductance reduction from the initial value, or coil temperature to rise by 20 c, whichever is smaller. (referece ambient temperature 20 c) (3) self-resonant frequency is measured with a network analyzer model 3577(hp), ms560j(anritsu), or equivalent. (4) dc resistance is measured with a digital multimeter tr6871 (advantest) or equivalent. (5) self-resonant frequency is for reference only.
