Application areas of power inductors

Chip inductors, also known as power inductors, high current inductors, and surface chip high power inductors. It has the characteristics of miniaturization, high quality, high efficiency energy storage and low resistance. The power inductors are widely used in digital products, PDAs, notebook computers, mobile phones, network communications, graphics cards, LCD backlights, power modules, automotive electronics, security products, office automation, home appliances, walkie-talkies, electronic toys, wireless communications, information technology equipment , Radar detectors, automotive electronics, cellular phones, pagers, audio equipment, sports equipment and medical equipment. Generally speaking, the application of power inductors is very extensive.

Power inductor precautions

(1) When using an inductor, pay attention to humidity and dryness, high or low ambient temperature, high or low frequency environment, perception of inductor performance, or impedance characteristics, etc.;

(2) The frequency characteristic of the inductance at low frequencies, like a chip inductor, presents inductive characteristics, only causing energy accumulation and filtering high-frequency characteristics. However, the impedance characteristics appear significantly at high frequencies. There are phenomena such as energy heating and reduced inductive effects. Different inductors have different high frequency characteristics;

(3) The large current that the inductance setting should bear and the corresponding heating condition;

(4) When using a magnet, find out the corresponding l value according to the magnet part above, which corresponds to the use range of the material;

(5) Pay attention to wires (enameled wires, sandbags or bare wires), commonly used enameled wires. To find the most suitable wire diameter.
