Understanding SMD Power Inductors From Their Structure and Selection | Zxcompo
SMD power inductor, as a surface mount electronic component, has been widely used in various types of electronic equipment due to its miniaturization, high power processing capabilities, and high energy storage.
They generally have low impedance characteristics and play a key role in computer display boards, notebook computers, digital cameras, pulse memory programming, and DC-DC converters.
In addition, SMD power inductors are also commonly used in various electronic circuits such as buck-boost converters, liquid crystal displays, and handheld note-taking devices.

SMD power inductors can be divided into many types based on their structure and manufacturing processes. Common ones include wire-wound type, multilayer type, braided type and film chip inductors. Among them, wire-wound type and multilayer type are the two most commonly used types.
Wire-wound inductors have the characteristics of wide inductance range, high precision, low loss and large allowable current, but they are limited in further miniaturization.
The multilayer inductor has the advantages of small size, good magnetic shielding, high mechanical strength and good heat resistance, but the inductance is relatively small and the Q value is low.

When selecting SMD power inductors, key factors to consider include inductance value, rated current, DC resistance and other parameters. The current rating is particularly important as it relates to the thermal stability of the inductor under normal operating conditions.
Generally, there are two rated currents for inductors, one is the heating current defined based on the thermal effect of the inductor temperature rising, and the other is the saturation current, which is the current value when the inductor value drops by 30%. The correct selection of the appropriate inductor current rating is crucial to ensure efficient and stable operation of electronic equipment.
To sum up, SMD power inductors are diverse in type and unique in function. When selecting, multiple technical parameters need to be comprehensively considered to ensure their correct application and performance in the circuit.
