Characteristics and features of surface mount inductors

The characteristics and features of chip inductors are used in many electronic fields, also known as chip power inductors, high current inductors, and surface mounted high-power inductors. Surface mount inductors have the characteristics of small size, high quality, high energy storage, and low resistance. What are the specific characteristics and usage features of chip inductors, which are smaller and more suitable for small electronic products?

Characteristics of SMT inductors:

1. Flat bottom surface is suitable for surface installation;

2. Excellent end face strength and good welding performance;

3. Has a high Q value and low impedance;

4. Low leakage magnetic flux, low direct resistance, and high current resistance;

5. Can provide braided packaging for easy automatic assembly.

Characteristics of SMT inductors:

1. Surface mounted high-power inductors;

2. It has the characteristics of miniaturization, high quality, high-energy storage, and low resistance;

3. Mainly used for computer display cards, laptops, pulse memory program design, and DC-DC converters;

4. Can provide scroll packaging, suitable for automatic surface mounting.

The anti inductance of surface mount inductors:

The induction size of the chip inductor is related to the inductance l of the chip inductor and the frequency f0 of the alternating current flowing through the chip inductor

The five calculation formulas are as follows: XL=2π FL。

XL is the inductive impedance of the chip inductor: f is the frequency of the alternating current flowing through the chip inductor; L is the inductance of the chip inductor. Through this calculation formula, we can further understand the relationship between inductance, inductance, and frequency.

When AC current passes through the chip inductor, the effect of induced resistance on AC current is similar to the obstruction of resistance on current. Therefore, when analyzing circuits, the induced resistance of the chip inductor can be equivalently understood as resistance. The resistance in an equivalent circuit is related to frequency and the size of inductance, making it a special type of inductive resistance.
