Application fields of power inductors and precautions to be taken

Chip inductors are also known as power inductors, high current inductors, and surface mounted high-power inductors. Featuring miniaturization, high quality, high-efficiency energy storage, and low resistors. So let's follow the editor to understand where power inductors are used and what precautions should be taken in their application.

Power inductor application field

The products are widely used in digital products, PDAs, laptops, mobile phones, network communication, graphics cards, LCD backlights, power modules, automotive electronics, security products, office automation, home appliances, walkie talkies, electronic toys, wireless communication, information technology equipment, radar detectors, automotive electronics, cellular phones, pagers, audio equipment, sports equipment, and medical instruments. Overall, power inductors are widely used.

Precautions for power inductance

(1) When using inductors, attention should be paid to humidity and dryness, high or low ambient temperatures, high-frequency or low-frequency environments, perception of inductance performance, or impedance characteristics, etc;

(2) The frequency characteristics of inductors exhibit inductance characteristics at low frequencies, similar to chip inductors, which only cause energy accumulation and filter out high-frequency characteristics. However, impedance characteristics appear significantly at high frequencies. There are phenomena such as energy heating and reduced sensory effects. Different inductors have different high-frequency characteristics;

(3) The high current that the inductance should withstand and the corresponding heating conditions;

(4) When using a magnet, find the corresponding l value based on the magnet section above, which corresponds to the range of use 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;
