Types and functions of commonly used chip inductors

We all know that there are many types of chip inductors on the market, and they are used in a wide range of scenarios. There is a kind of inductor on the market because it can be more suitable for automated production plants and is widely used. It is a chip inductor. Let’s take a look at its package size.

There are many kinds of chip inductors on the market, which have the characteristics of miniaturization, high quality, high energy storage and low resistance. So what are the types of inductors?

1. Wire-wound chip inductors: wide inductance range from mH to H level, high precision, low loss, large current, relatively simple process, low cost, etc.

2. Multilayer chip inductors: good magnetic shielding, high sintering density, and good mechanical strength. Its size is small, and the integrated structure has good heat resistance.

3. The film is a chip inductor: it has the characteristics of maintaining high Q, high precision, high stability and small size in the microwave frequency band. Its internal electrodes are concentrated on the same layer, and the magnetic field distribution is concentrated, which can ensure that the device parameters after mounting do not change much, and it can show good frequency characteristics above 100MHz.

4. Braided chip inductors: The characteristic is that the unit volume inductance at 1MHz is larger than other chip inductors, small in size, and easy to install on the substrate. Used as a miniature magnetic component for power processing.

The application fields of chip inductors are: smart home, mobile phone communications, displays, auto parts, medical equipment, etc.
