Welcome to wholesale electronics low profile smd inductor, low resistance smd power inductor, low dcr smd power inductor, high-current smd shielded inductor, magnetic shielded surface mount inductor from our factory.

Chip inductors are surface-mounted inductors that are divided into power inductors, high-power wound inductors and high-current winding inductors, shielding inductors, and so on. It has the characteristics of small size, high quality, high energy storage and low resistance, convenient and quick placement.

The hollow coil in the general electronic circuit, or the coil core, can only withstand a lower voltage through a lower current; the power inductor also has an air-core coil, and also has a magnetic core, the main feature is to use a thick wire winding. It can withstand tens of amps, hundreds, thousands, or even tens of thousands of amps.

Power chip inductors are divided into two types: shielded and unshielded. They are mainly made up of magnetic core and copper wire. In the circuit, it mainly plays the role of oscillation and filtering anti-interference.

Matters need attention of chip inductor:

1. The design of chip inductor should consider large current and the corresponding heat generation.

2. When using the magnetic ring for the chip inductor, compare the magnetic ring part to find the corresponding value of l, and the corresponding scope of use of the material.

3, pay attention to the wire (enamel wire, yarn package or bare wire), commonly used enameled wire. To find the most suitable line.

4, Pay attention to the environment humidity , the temperature of the environment, high-frequency or low-frequency environment, the inductance of the sensory, or impedance characteristics, etc.

5. When the chip inductor is at low frequency, the chip inductor generally exhibits an inductive characteristic, which only functions as energy storage and high frequency filtering. However, at high frequencies, its impedance characteristics are very obvious. There are energy consumption and heat generation, and the inductive effect is reduced. The high frequency characteristics of different inductors are different.
