Among electronic components, the bead inductor is a very important passive component. This component can store and release energy by generating an induced magnetic field in the circuit, which can effectively implement filtering, amplification, regulation and protection functions, and play a key role in many applications.
Bead inductors are inductive components made by enclosing ferrite particles on a layer of windings. Ferrite particles have a high magnetic induction intensity, and this winding structure increases the value of the inductance. Bead inductors are widely used, mainly in the field of power supply, communications, consumer electronics and medical fields.
In this article, we will list the top 15 bead inductors companies in the world to help you choose the right supplier. Also if you are looking for a professional PCBA manufacturer, then IBE will be a good choice.
