Many people still lack understanding of the different types of SMD inductors. For example, they think that this type of product is only suitable for restricted products. In fact, the inductor principle is the same.
SMD inductor, full name Surface Mounted Device Inductor, refers to an inductor made using printed circuit manufacturing technology, directly mounted on the surface of the circuit board, and connected to other components through pins. It is usually composed of a magnetic core and a cover plate. The magnetic core is wound with a winding of high conductivity wire, which has an inductance effect on signals of a specific frequency.
The main functions of an inductor are boosting, filtering, and energy storage. Simply put, it is a passive component that works when current passes through it, blocking noise and alternating current, while allowing stable and tributary currents to pass through and blocking communication.
The working principle of SMD inductors is based on the law of electromagnetic induction. When an alternating current passes through an SMD inductor, an alternating magnetic field is generated in the inductor. Due to the change in this magnetic field, an alternating voltage is generated inside the inductor. The magnitude of this alternating voltage is related to the input alternating current, and the resistance of the inductor itself will also affect the working effect of the SMD inductor.
Inductors use this effect to store and release magnetic field energy.
Inductors play a very important role in circuits, but people often overlook their role. Many solution companies choose substitutes to further save costs in batches after choosing a company’s product production plan.
In fact, the inductor products produced by different brands of SMD inductor manufacturers are not the same. Some high-quality manufacturers (including Zxcompo) will use high-grade raw materials and mature processes. On the premise of ensuring product quality and after-sales service, the unit price of inductors often hopes that the manufacturer’s other sizes are opposite and the volume is smaller.

Any inductor can be used in any electronic product. As long as the machine can be installed on the board and the parameters such as inductance, current resistance are consistent, there will be no problem.
SMD inductors are widely used in various electronic devices, such as mobile phones, laptops, TVs, digital cameras, etc. Its main function is to filter digital and analog signals, such as reducing power supply ripple and removing high-frequency noise. In addition, in RF circuits, SMD inductors can also be used for coupling and matching circuits, because it can change the impedance characteristics of the circuit.
Industrial-grade products generally have higher requirements for SMD inductors. There are scientific research, aerospace, and higher requirements for the stability, temperature resistance, and weather resistance of inductors. Therefore, shielded or die-cast inductors must be used.
