L 0 001n2d 228d 2 254l where. The length of the coil is 1 cm. L is the inductance in henry s. Enter the coil length distance from first to last winding see diagram.

Single layer and multilayer air core inductors toroidal air core coil inductance inductors on ferrite rings in pot core flat coils on the pcb and also lc tank parameters the program has additional plugins to calculate another manner of coils. Air core inductor coil inductance calculator. The calculator determines the inductance of a single layer coil. Advantages of an air core coil.

Some others are wound on a bobbin made of bakelite plastic ceramic etc. Could this be possible. Air core inductor designer calculator. D is the coil diameter in meters.

Calculate the inductance of a single layer coil of a 10 turn air core coil wound on a cylindrical former with a diameter of 2 cm. Diameter and length of inductor are entered in millimetres along with the number of turns. Enter the number of turns windings. An air core inductor is an inductor that does not depend upon a ferromagnetic material to achieve its specified inductance.

D coil diameter in inches inches l coil length in inches inches n number of turns inductance. Coil32 is a free coil inductor calculator that allows calculating. Enter the coil diameter form diameter wire diameter see diagram. Formula equations for inductance of air core inductor calculator inductance of an air core coil inductor l n2 x d2 18d 40l μh where n number of turns d inductor coil diameter l inductor coil length.

Select the measurement units inches or centimeters. Some inductors are wound without a bobbin and just air as the core. The following is a design tool which calculates the inductance of an air core inductor. Single layer air core inductor calculator the calculation is based on the classic wheeler s formula for single layer inductance air core tightly wound which dates back to the radio days of the 1920s.

The inductor is a common school use transformer 5000 turn coil with wire diameter about 0 15mm the official air core value is 0 6h however when i calculate the iron core got a result of 105h. This calculator is useful when making antenna matching units low pass filters crystal sets antenna traps resonant circuits or anywhere where an air cored single layer inductor is required.
