Notes - Horizontal - Series 618

  1. Minimum inductance is measured with the core halfway out of the coil form.

  2. Electrical measurements were made with the material and length shown in the electrical specifications. Outside diameter and thread of the core used in series 618 is 6-32.

  3. Winding O.D. of series 618 coils is .211". Pitch is determined by the turn count.

  4. Series 618 coils may be tuned with Standex tuning wrench 996.

  5. Coil form material is polypropylene. Higher temperature material is available on some series

  6. Standex specifications are subject to change without notice.
