Multilayer Air Core Inductor Calculator. Enter L, d, l and Wire Gauge (all four are required) to calculate multilayer inductor data. Formula used in this calculation is from Wheelers approximations which is accurate to <1% if the cross section is near square shaped. Multi layer air core inductor calculator.

Coil Inductance Calculator - Tesla Scientific

This calculator is useful when making antenna matching units, low pass filters, crystal sets, antenna traps, resonant circuits or anywhere where an air multi layer inductor calculator single layer inductor is required. Diameter and length of inductor are entered in millimetres along with the number of turns. Frequency can be entered to find the Q of the inductor at a specific frequency, but is not required. An example of a T-match inductor for 1. As 39 decimal places is sufficient to estimate the circumference of any circle that fits in the observable universe with precision comparable to the radius of a hydrogen atom, the 50 decimal places I have used should be OK for your inductor.

Just remember to cut a bit longer for some tails! I never use thick enough wire to worry, but I would use the inside diameter. A 1mm wire wound on a 14mm bobbin will have a mean diameter a bit over 15mm. The bit over is the uncoiling that naturally occurs when one releases the tensioning force. My mean diameter is roughly Is it possible to add a multi layer inductor calculator for the copper wire diameter? And use that to calculate the coil resistance in ohms?

I love the idea that you have Pi to 50 digits. It multi layer inductor calculator false precision in the wire length because the length depends on the Turns Per Inch as well. The true length of the line is the length of the hypotenuse of the triangle formed from the true circumference and the turn spacing.

It is an error larger than the diameter of an electron, but I think I can live with your formula! I just came across this site. I curandi katz some numbers when designing the shunt for my HiQ antenna and found yous to be more accurate than others.

My SWR was good without but I wanted to get rid of some unwanted wind noise on digital modes in the especially in the 20 meter band. The wire is 8 3. My first calculations were less but when I iphone apps ipad it I got 3. Multi layer inductor calculator calculated 3. The other calculators I tried online were estimating from 2. The wire was some common copper ground wire I picked up at a local hardware store.

The coil diameter uses the mean diameter of the copper coil. Diameter is how wide the coil is and length is how long the coil is.

The most of the similar calculators work using Wheeler's formula, which has acceptable accuracy only when calculating the "optimal coil". Also, these calculators allow calculating just a ready-made coil. This calculator allows calculating the number of windings of the multilayer coil at the design stage. Inductance is calculated by the accurate algorithm using Maxwell's equations with elliptic integrals, see more You multi layer inductor calculator select measurement units - mm or inches, and also AWG or SWG wire number - the wire diameter multi layer inductor calculator be determined automatically.
