How to adjust the inductance value of a larger or smaller inductor coil

Recently, whenever we encounter customers, they always raise a question: How can we adjust the inductance value of the coil in the product? And how can we address such a question?

The inductance is an important performance indicator of an inductor coil. Those who have some knowledge of inductors should all believe that adjusting the inductance of an inductor coil is quite simple, because the magnitude of the inductance of a coil mainly depends on the number of turns (windings) of the coil, the winding method, the presence or absence of a magnetic core, and the material of the magnetic core. Generally, adjusting the number of turns of the inductor coil, the magnetic core, and the material can effectively adjust the inductance.

And today, what we are introducing is how to adjust the inductance of an inductor coil while keeping the number of turns, winding method, presence or absence of a magnetic core, and the material of the magnetic core unchanged.

Method one can achieve different inductance values of the product's inductor coil in the overall circuit by changing the connection method. When multiple inductor coils are connected in parallel, the inductance value is the smallest. When multiple inductor coils are connected in reverse series, the inductance value of the circuit is the largest.

Method 2: By adjusting the spacing of the inductor coils within the product, the magnitude of the inductance can be changed.

Method 3 changes the inductance by adjusting the position of the magnetic core within the inductor coil.

Method 4: In the circuit of the product, the sliding of the switch is utilized to change the number of turns of the coil, thereby altering the inductance.

In fact, there are many other methods for modifying the inductance of the coil. In summary, adjusting the product structure and coil structure is the key consideration. However, not all coil manufacturers can do this because there are many technical issues involved in this process. Although the coil is just a simple electronic component, it plays many roles in electronic products, and a single issue can affect the entire system. Only companies with sufficient R&D capabilities and experimental testing capabilities have the ability to control all aspects. Fuhong Electronics has gained a deep understanding during its long-term process of meeting customer needs.
