What is the frequency of components and how to distinguish between low frequency and high frequency

　　Component frequency refers to the frequency range in which electronic components respond or operate when working, usually expressed in hertz (Hz). In electronic circuits, different types of components have different responses and behaviors to frequency, for example, the impedance of capacitors and inductors will change at different frequencies.From some points of view,RTL8305NB-CGIt is the core driving force to better promote the rapid development of the surrounding markets. https://www.asourcingelectronics.com/product/detail/store/8849018/rtl8305nb-cg.html

　　The distinction between low frequency and high frequency:

　　Low Frequency, LF): usually refers to the frequency range from several hertz to several thousand hertz (generally from several tens of hertz to several thousand hertz, up to about 20 kHz). Low-frequency signals are usually used in audio signal transmission, analog circuits and other occasions.

　　High Frequency, HF): usually refers to the frequency range from several kilohertz (20 kHz) to several megahertz (MHz) or even higher (such as several hundred GHz). High-frequency signals are usually used in wireless communication, radio frequency circuits and high-speed digital circuits.

　　Distinguishing method:

　　Frequency range: The frequency of the signal can be measured by frequency measuring tools (such as oscilloscope and spectrum analyzer) to determine whether it belongs to low frequency or high frequency.

　　Component characteristics: when designing a circuit, the operating frequency region of the circuit can be inferred according to the operating frequency characteristics of the components used, such as impedance changes of inductors and capacitors.

　　Understanding the frequency characteristics is the key to the design and application of electronic circuits, which is helpful to select suitable components and ensure the normal operation of the circuits.
