(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). unit: mm solder pad no paste no paste solder pad note: =p3 is added to each part number to indicate tape and reel packaging.
