Air Core Coil Calc

Air core inductor coil inductance calculator.

Air core coil calc. Could this be possible. Get help for the inductor designer close. 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. The calculator determines the inductance of a single layer coil.

Coil inductance calculator to calculate the inductance of a single layer air core coil. Advantages of an air core coil. Diameter and length of inductor are entered in millimetres along with the number of turns. L is the inductance in henry s.

L is the coil length in meters 0 8radius n is the number of turns. Some others are wound on a bobbin made of bakelite plastic ceramic etc. The following is a design tool which calculates the inductance of an air core inductor. 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.

An air core inductor is an inductor that does not depend upon a ferromagnetic material to achieve its specified inductance. Some inductors are wound without a bobbin and just air as the core. 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. 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.

The length of the coil is 1 cm. L 0 001n2d 228d 2 254l where. 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. Select the measurement units inches or centimeters.
