Inductor Data

It is easy to find the inductance of an inductor using equation shown on Figure 1. However, very often ham use for implementation of the inductor some normalized forms. So, it is possible to do tables that are contained data for such forms.

Table 1 (Reference 1) contains data for inductor coiled on a form in 18 and 20 mm diameter. L- length in mm, N- numbers of turns.

Example: Inductor coiled on the form in 18 mm diameter by 10 turns on length 20 mm has inductance 1.153-μHn.

Table 2 (Reference 1) contains data for inductor coiled on a form in 25 AND 30mm diameter. L- length in mm, N- numbers of turns.

Example: Inductor coiled on the form in 30 mm diameter by 10 turns on length 20 mm has inductance 2.687-μHn.

Table 3 (Reference 1) contains data for inductor coiled on a form in 40 and 50mm diameter. L- length in mm, N- numbers of turns.
