• All Assemblies sold Un-wound

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 one piece base and coiform is molded from ploycarbonate. The 5 terminals are brass, .02 inches (0.5mm) in diameter, tin plated to meet MIL-STD 202 method 208 for solderability.

7) The Iron Powder tuning cores are a 6-32 shallow thread. The ferrite tuning core is 3.3mm metric. All core are coated with Teflon.
