2427

      The 2427 series(Insert Molded Coil) are tested by the equipment of Q meter (HP 4342A), which is measured in this way: inductance below 0.1uH calculated from readings taken at 50MHz; Inductance greater than 0.1uH read at recommended Q meter frequency; Q and L measured with 1/2" long of TCW#16 soldered along the coil leads and with one end flush with the bottom of the coil then bent 1/4" down from stand off at an angle of 90°; L min. measured with core halfway out of the top of the form.
      The 2427 series possess features of Plastic molded, High reliability, Low cost. The  electrical specification of the 2427 series are got. 2427-01(L Min. (uH):0.056, L Nom. (uH):0.058, L Max.
