What factors are related to the inductance of air-core inductors?And what is its calculation formula?1. Calculation formula of inductance of air-core inductor: First use paper to make a small cylinder, and then wind an inductor coil on the cylinder to make an air-core inductor. Calculation formula of air-core inductor: LmH)=(.08DD.NN/(3D+ 9W+10H) 1. This can calculate the number of turns of the winding inductor: Number of turns = [Inductance* { (18*turn diameter (inch)) + (40 * turn length (inch))}] ?turn diameter (inch) ) Number of turns = [8.116 * {(18*2.047) + (40*3.74)}] ?2.047 = 19 turns The number of turns can be calculated based on the above points: Number of turns = [Inductance* { ( 18* Turn diameter (inch)) + (40 * loop length (inch))}] ? loop diameter (inch) number of loops

Passive components, also known as passive components, refer to circuit components that do not affect the basic characteristics of the signal and only allow the signal to pass through without changing it.The most common ones include resistors, capacitors, inductors, ceramic oscillators, crystal oscillators, transformers, etc.From the perspective of working characteristics, passive components have the characteristics of not consuming electrical energy themselves, or converting electrical energy into other forms of energy; at the same time, they only need to input signals and can operate normally without the need for an external power supply.According to different industry definitions, the scope of passive components will be different, and sometimes RCL components are equivalent to passive originals.This question will focus on the RCL component market, that is, the market for capacitors, resistors, and inductors.Passive components appearing in this article refer to RCL components.Overall, as the most basic electronic components, the total demand for RCL components has steadily increased, and with the demand for miniaturization and lightweight of downstream end products, chip components have become RCL
