Patch inductor is used in many electronic fields. Patch inductor is also called power inductor, high current inductor and surface mount high power inductor. Patch inductor has the characteristics of small size, high quality, high energy storage and low resistance. The chip inductor is smaller and more suitable for small electronic products. What are the specific characteristics and application characteristics of the chip inductor? Let's have a look.
Characteristics of patch inductance
(1) the flat bottom surface is suitable for surface installation;
(2) Excellent end strength and good weldability;
(3) High Q value and low impedance;
(4) Low leakage magnetism, low direct resistance and high current resistance;
(5) Ribbon packaging can be provided to facilitate automatic assembly;
Chip inductance characteristics
(1) high-power inductors are attached to the surface;
(2) It has miniaturization, high quality, high energy storage and low resistance;
(3) It is mainly used in computer display cards, notebook computers, pulse memory programming and DC-DC converters;
(4) It can provide reel packaging, which is suitable for automatic surface installation;
Inductive impedance characteristics of patch inductor
The inductance of the chip inductor is related to two factors: the inductance L of the chip inductor and the frequency f0 of the alternating current flowing through the chip inductor. The formula for calculating the inductive reactance of the chip inductor is XL=2πFL. In the formula, XL is the inductance of the chip inductor, and f is the inductance of the chip inductor at the frequency of AC current. Through this formula, we can further understand the relationship among inductance, inductance and frequency.
When AC current passes through the patch inductor, the influence of inductor on AC current is similar to that of resistance on current. Therefore, when analyzing the circuit, the inductance of the chip inductor can be understood as equivalent resistance. The resistance in equivalent circuit is related to frequency and inductance, so it is a special kind of inductance resistance.
