• Repeatable Inductance and High Q
• Superior Temperature Stability
• This Series a Toko 10mm Equivalent
• Winding Capacity table
• Q vs Frequency Graphs
• All Assemblies sold Un-wound

1) The iron powder or ferrite 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 molded in phenolic thermoset. The attached coiform is molded in polypropylene. The 5 terminals are brass, ".027 inches (.07mm) in diameter, tin plated to meet MIL-STD 202 method 208 for solderability."

7) The Iron Powder tuning cores are 8-32 shallow thread. The ferrite tuning core is 3.7mm metric. All core are coated with Teflon. Tool-A is the recommended adjustment tool.
