What is an inductor in IC knowledge popularization? 2

However, inductors also have their limitations. For example, their physical size is usually larger than capacitors or resistors, which can be a problem in size limited circuit board designs. In addition, when current passes through an inductor, heat may be generated in the coil, which requires consideration of heat dissipation during design. diode

Inductors can be classified based on their construction, application, or characteristics. Some common types include:

1. Fixed inductor: The inductance value of this inductor is fixed and cannot be adjusted, and it is widely used in various circuits.

2. Variable inductor: This type of inductor allows users to adjust the inductance value and is typically used in applications such as wireless receivers that require fine tuning.

3. Hollow coil: This type of inductor has no magnetic core and is composed only of coils, typically used in high-frequency applications.diode

4. Iron core inductors and ferrite inductors: These inductors use iron or ferrite as the magnetic core to store more magnetic energy and are typically used in power electronics and low-frequency applications.

Choosing the appropriate type and specifications of inductors is crucial when designing circuits. Designers need to consider factors such as inductance value, maximum current carrying capacity, self resonant frequency, DC resistance, and size.

In short, inductors are indispensable components in electronic design, playing an important role in the transmission, regulation, and storage of electrical energy. With the development of electronic technology, the demand for inductor performance is constantly increasing, which promotes the advancement of materials science and manufacturing technology.diode
