Power chip inductors, also known as power inductors, are called chip inductors in English; It is a high-current inductor and a high-power inductor with surface patches. It has the characteristics of miniature, high quality, efficient energy storage and low resistance. Under normal circumstances, the inductance in the electronic circuit is an air-core coil or a coil with a magnetic core, which can only pass a small current and bear a low voltage; Power inductors also have air-core coils and coils with magnetic cores, which are mainly characterized by being wound with thick wires and can withstand tens, hundreds, thousands or even tens of thousands of amps. Then, what are the application and precautions of power chip inductor? The following is answered by Xiaobian.
Application of Power Chip Inductor
Power chip inductors are widely used in digital products, PDA, notebook computer, mobile phone, network communication, graphics card, LCD backlight, power module, automotive electronics, security products, office automation, household appliances, walkie-talkies, electronic toys, wireless communication, information technology equipment, radar detectors, automotive electronics, cellular phones, pagers, audio equipment, sports equipment and medical equipment, etc. Generally speaking, power chip inductors are widely used.
Matters needing attention in the use of power chip inductor
(1) When using inductors, please pay attention to humidity and dryness, high or low ambient temperature, high or low frequency environment, sensing inductance performance, impedance characteristics, etc.
(2) The frequency characteristic of inductance is at low frequency, for example, the chip inductance shows inductance characteristic, which only causes the characteristics of energy filtering and high frequency filtering. But the remarkable characteristics of high-frequency impedance are accumulated. There are phenomena such as measurement characteristics. Have a low temperature feeling, low temperature feeling;
(3) The high current and corresponding heating conditions that the inductor should bear;
(4) When using magnets, find the corresponding L value according to the above magnet parts, which corresponds to the application range of materials;
(5) Pay attention to wires (enameled wires, sandbagged wires or bare wires), and enameled wires are commonly used. Find the most suitable diameter;
