Why is the application of SMD power inductors so good? It is inseparable from its own functional advantages!

At present, with the rapid development of electronic technology, electronic products have become more and more inseparable from people's lives, so SMD power inductors have also been used more and more widely. As for the reason?

SMD power inductor applications, SMD power inductors can be used in impedance matching applications to achieve impedance balance of data transmission lines. This is necessary to ensure efficient data transmission between ICs. Generally, the main functions it can undertake include circuit tuning, impedance matching, high-pass and low-pass filters, and can also be used as an RF choke. The Q value is a measure of the performance of power inductors. It is a dimensionless parameter used to compare the oscillation frequency and energy loss rate. The higher the Q value, the closer the performance of the power inductor is to an ideal lossless inductor. In other words, its selectivity in the resonant circuit is better. Another benefit of high Q is low loss, which means that the power inductor consumes less energy. A low Q value will result in a wider bandwidth and a lower resonance amplitude at and near the oscillation frequency. The true measure of a power inductor is of course its inductance value. For audio and power applications, the value of power inductors is usually a few henries, while higher frequency applications usually require much smaller inductances, usually in the millihenry or microhenry range. The power inductance value depends on several factors, including structure, core size, core material, and actual number of turns of the coil.   SMD power inductor applications, when selecting power inductors, the working current should be lower than the rated current in the manual. If the working current exceeds the rated current, the product may be damaged. SMD power inductors have a wider value range than thin-film or air-core coils, but they are not as good as the inductance range or rated current of wire-wound components. SMD technology is becoming more and more popular due to its good electrical characteristics, especially its low cost. However, when purchasing chip inductors, we must pay attention to some details. In order to ensure the quality of the purchased chip inductors, the choice of brand is also very important. Now there are many brands on the market, so everyone chooses Be sure to look for the genuine product when you buy it, in case you buy fake products.
