Introduction of inductor wire diameter and number of turns| GETWELL

The thicker the inductance wire diameter is better or better; What does it have to do with the number of turns? Now the inductor distributor gives you a description.

Inductance wire diameter

Those who know about inductance should know that an inductor is usually composed of skeleton, winding, shield cover, magnetic core, packaging materials and other components. Toroidal Inductance material is particularly important, and the wire diameter of enameled wire is often discussed.

We have been looking for a period of time on the market to see if we can make the wire diameter of the Toroidal inductor very thin. We have tested many types of inductors, but none of them reached the expectation, which led to the failure of the whole project. Some products are a high voltage output power supply, inductance wire diameter requirements is to be good performance, wire diameter to be fine.

At present, the conventional inductor wire diameter of the industry is 0.1-0.6mm, which is also the main specification of most inductor manufacturers. The line diameter below 0.1mm and above 0.6mm is considered as the factory production scale, because not most inductor manufacturers have the technical ability to do this. At present, the inductor wire diameter can be 0.03mm, the thickest can be 2.0mm.

The thickness of inductance wire diameter will affect inductance inductive value, resistance, temperature rise, inductance size, etc., so it is not practical significance to discuss inductance wire diameter without considering the specific use environment. It is necessary to select the appropriate wire diameter based on the actual use requirements. However, it is certain that whether the inductor wire diameter is thinner or thicker, the production capacity and research and development capacity of the factory are tested.

The relationship between inductance and number of turns

The inductance is proportional to the square of the number of turns, that is, the inductance is proportional to the square of the number of turns, and is independent of the number of turns per volt of the transformer.

Transformer per volt turns is related to the size and quality of the core, and the inductance per turn is also related to the size and quality of the core. Transformer with more turns per volt has less inductance per turn.

If the iron core remains unchanged, increasing the number of turns of the winding can provide greater inductance and more energy, which is good, but it increases the internal resistance, which is bad. With the windings unchanged, the wafer core has fewer magnetic vortices, lower losses, and can pass through higher frequencies. But occupy a large number of gaps, magnetic circuit is also long. A lot of people go for low internal resistance to get a better high-frequency response, and high inductance to get more current to increase the low frequency sensitivity." Around the heat will be small, the internal resistance will become large, the power becomes smaller, the influence of large dynamic. The more the primary winding number is, the greater the inductance will be, and the greater the obstacle to AC will be. Therefore, excessive winding number will inevitably lead to the decline of output power and the supply of large current.

The above is a simple introduction of inductor wire diameter and number of turns. If you want to know more information about inductors, please contact our inductor suppliers. I believe we can give you more professional and detailed information.
