1) The iron powder materials are used in the tuning core and cup core.

2) This represents the frequency range for Q optimization in tuned or resonant circuits. The inductive properties of the material is effective over a considerably wider frequency range.

3) Nanohenries (10^-9Henries) per turn squared.

4) The minimum inductance is measured in microhenries (10^-6 Henries) per 100 turns with the tuning core tuned out of the winding area but still a part of the assembly.

5) The temperature stability is of the magnetic material, measured in parts per million per degree Celsius (ppm/° C) on a toroidal core and winding. This is only an indication of the temperature stability for a complete wound assembly.

6) The base is moulded from thermoset Diallyl Phthalate (DAP). The 4 or 5 terminals available are half hard brass. .024 inches in diameter tin plated to MIL-STD 202 Method 208 for solderability. Optional base B524 is available with .050 standoffs.

7) The CF115A coil form is a glass reinforced polyester tube with 6-32 internal threads. The NF coil form is self threading nylon 6/6.

8) The tuning core is 6-32 shallow thread coated with Teflon. Tuning-Tool-A is the recommended adjustment tool.
