What are the common categories of chip inductors | GETWELL

What is the common classification of chip inductors, the following professional chip inductors manufacturers to interpret for you.

Chip inductors, also known as surface-mount inductors, are a new type of wireless or short wire microelectronic components suitable for surface mount technology (SMT), like other chip components (SMC and SMD).Its lead end and welding surface in the same plane.

SMD inductors are classified according to their construction forms, and according to their construction and manufacturing process, chip inductors can be divided into two types: insert type three-dimensional inductors and mount type chip inductors.The main manufacturing process for conventional cartridge inductors is winding, in which a wire is wound around a magnetic core to form an induction coil (also commonly a hollow coil).Its main characteristics are wide range of inductance, high precision of inductance value, high power consumption, simple production, short production cycle, and sufficient supply of raw materials.The disadvantage is that the automation production process is low, the production cost is high, not easy miniaturization and lightweight.

According to the manufacturing process of PCBA, there are four main types of chip sensors: wound, laminated, braided and thin film.

The following are the four types of chip inductors

Wound inductor and laminated inductor are commonly used. The former is the product of miniaturization of traditional wound inductor.The latter is made by multi-layer printing technology and laminated production process, and its volume is smaller than that of the wound chip inductor, which is the key product in the field of inductor components.

(1) Wound type:

It is characterized by wide inductance range, high precision, small loss, large allowable current, strong production process inheritance, simple, low cost.But the downside is that you're limited in scaling it up further.Ceramic-based wound inductors can maintain stable inductance and relatively low loss at high frequencies, so they play an important role in high frequency circuits.

(2) laminated type:

Good magnetic shielding, high sintering density, good mechanical strength.Disadvantages are low pass rate, high cost, small inductance, large loss.

Compared with the wound chip inductor, it has many advantages: small size, which is conducive to the miniaturization of the circuit;The magnetic circuit is closed so that it does not interfere with the surrounding components or be interfered by neighboring components.It is conducive to high density installation of components.Integrated structure, high reliability;Heat resistance, good weldability;Regular shape, suitable for automatic surface mounting production.

(3) Braid type:

Its characteristic is that the unit volume inductor below 1MHz is larger than other chip inductors, small volume, easy to install on the substrate.A miniature magnetic element that can be used for power processing.

(4) Thin film type:

Low loss, high precision, high stability and small volume in microwave frequency band.The internal electrodes are concentrated at the same level and the magnetic field distribution is concentrated, which can ensure that the parameters of the components change little after installation and present good frequency characteristics above 100MHz.
