Power inductors are a type of inductor with high inductance values and the ability to handle high currents. They are primarily used in circuits such as power supplies, converters, and inverters to filter out high-frequency noise, stabilize voltage, and limit current, playing a crucial role in ensuring the normal operation of the circuit.

But when using power inductors, we must pay close attention to these matters:

When using inductors, pay attention to factors such as humidity and dryness, high or low environmental temperatures, high or low frequency environments, the inductor's performance perception, or impedance characteristics.

(2) At low frequencies, such as in surface mount inductors, the inductor exhibits inductive characteristics, causing only energy storage and filtering of high-frequency signals. However, at high frequencies, the impedance characteristics become pronounced, leading to phenomena like energy dissipation through heat and reduced inductive effects. Different inductors exhibit varying high-frequency characteristics.

(3) The inductor's setting should withstand the high current it encounters and the corresponding heat generation.

(4) When using magnets, refer to the above magnet section to find the corresponding l value, which corresponds to the material's usage range.

(Note: Pay attention to conductors, commonly including varnished wire, sand-covered wire, or bare conductors.)
