Common Mode Chokes: PL8210NL Application Field and Working PrincipleCommon Mode Choke, otherwise known as a common-mode filter, is an important electronic component used to filter out noise from power and communication applications. It has become an integral part of modern electronic design, providing both EMI/RFI filtering and ESD protection. This article will discuss the application field and working principle of the Zetex PL8210NL common mode choke, an upgraded version of the popular E-class PL8210 common mode choke which provides higher performance in a compact package.The PL8210NL is an economical solution for filtering unwanted high frequency noise in high-speed digital and mixed-signal circuits. It is designed to suppress common mode noise generated by switching power supplies, various digital controllers and data converters, as well as signal line cross-talk, while still providing high common mode suppression.In terms of application field, the PL8210NL is suited for use in a wide range of consumer electronics, industrial, and automotive products. In consumer electronics it finds widespread use in laptops, mobile phones, and tablets. In industrial applications it can be used to help clean up motor control circuits, as well as process control and industrial control systems. In automotive applications, the PL8210NL can be used to reduce the EMI/RFI generated by ECUs, AC systems, audio systems, and other onboard electronics.The PL8210NL’s working principle is based on electromagnetic coupling. When two coils are placed close to each other, current in one coil creates a magnetic field, inducing an electric current in the other coil. This phenomenon, known as mutual inductance, is the basis for the common mode choke. By placing two identical coils in series, one for each signal, the electric signals can be passed through the device while the current induced by the electric signal is canceled out. This effectively suppresses higher frequencies while allowing lower frequencies to pass through.Another advantage of the PL8210NL is that it has a low DCR (direct current resistance). This is important because it allows for higher currents to be passed with less overheating and voltage drop. It also helps reduce system noise, further improving signal quality.The PL8210NL has a wide range of applications and advantages. Its compact size and economical construction make it an ideal choice for filtering out high frequency noise in high-speed digital and mixed-signal circuits. Its low DCR and electromagnetic coupling design make it an ideal choice for suppressing noise in a wide range of consumer electronics, industrial, and automotive components. Thanks to its impressive performance and ubiquity across the market, there’s no doubt that the PL8210NL is one of the most popular common mode chokes on the market.
