Power Inductor And High Current Inductor

Power inductor and high current inductor
Chip inductor is a property of the closed loop. When the coil of the inductor is through the current, the magnetic field is induced by the inductance of the inductor in the coil, and the induced magnetic field can generate the induced current to resist the current flowing through the coil. On chip inductor in the circuit is to produce changes in the non steady current through the magnetic field, the magnetic field will also affect the current, inductance in the power circuit in series such as inductance, inductance is direct to DC, the high frequency pulse is high resistance, so the DC resistance of AC pulse the role of.

Summary

This kind of chip inductor is also called: power inductor, high current inductor.

Advantage is:

1, surface mount high power inductors.

2, the characteristics of miniaturization, high quality, high energy storage and low resistance.

3, the main application in the computer display card, notebook computer, pulse memory program design, as well as DC-DC converter.

4, can be used to provide automatic packaging scroll packaging.

Because of the single structure and the coil technology, the low DC impedance and high capacitive current are realized;

Automatic surface loading;

Excellent weldability and environmental resistance;

Suitable for reflow soldering;

European RoHS counterpart;

Lead free terminal;

1, error / accuracy:

2 inductance inductance value: refers to the highway inductance at the frequency of 100Khz test value. Therefore, the brand value of different senses are also different.

3, self harmonic frequency: inductance and inductance of the formation of resonance frequency point. Therefore, in the application, do not exceed the self resonant frequency to use.

4, DC inductance: winding inductance DCR value will lead to heat.

5, saturation current: inductance value decreased by 30% of the current value.
