Notes - Series 752

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

  2. Carbonyl E & J material cores are available 1/4", 5/16", 3/8" or 1/2" long. Aluminum cores are available 5/16" long. Electrical measurements shown were made with 10-32, 3/8" long, carbonyl "E" or "J" core, as noted. Other core lengths and materials are available.

  3. Electrical winding "taps" are available on the 752 series.

  4. Series 752 windings are 22 TPI, and have an O.D. .285". Distance from the mounting surface to the first turn is .07".

  5. The short shoulder indicates the start lead.

  6. Series 752 is "spacewound".

  7. Coil form material is polypropylene.

  8. These coils may be tuned with Standex tuning wrenches 160, 55, 95, 302 or 764.

  9. Standex specifications are subject to change without notice.
