| fixed inductors for surface mounting ? ? nz ; { ????? (1) inductance is measured with a lcr meter 4284a * or equivalent. (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, or coil temperature to rise by 40c, whichever is smaller.
