Category: Material
Help edit

µ = Magnetic flux
（The calculator refers to Amidon products to calculate, with other company products can refer to this calculation results. ）

App Description

Input data: the amount of inductance you want, in mH; (ferrate) ferrite core size model ;Please select→Material Unit μ = Magnetic Flux

Output Data:

Actual inductance value, unit mH; number of turns; ring diameter, unit mm; AL inductance, unit mH/1000 turns

Usage example

The amount of inductance you want to get [mH] :100

(Ferrite) Ferrite Core Size Model : FT-23

Please select →Material :43::μ=850

μ = magnetic flux, time

Actual inductance value [mH] : 100.2

Number of turns [1] :73

Ring diameter [mm] : 5.84

AL inductance coefficient [mH/1000 circle]: 188

Note
