Common Mode Chokes are a type of EMI (Electromagnetic Interference) suppression device, used to reduce or eliminate noise and interference in electronic equipment. The PL8209 is a custom-designed common mode choke with a wide application range. It works in two different ways; to reduce noise or restrict signal transmission from components. This article looks at the PL8209’s application field, working principle, and features.

Application Field of the PL8209

The PL8209 is designed for use in both high-side and low-side applications that require a filter that will reduce common-mode noise and interference signals. It is especially useful when long input/output lines are present, where its unique common-mode noise filter is effective in cleanly eliminating any unwanted interference. Commonly used in industrial, automotive, and embedded/RF applications, the PL8209 enables reliable signal transmission between components.

Working Principle of the PL8209

At the heart of the PL8209’s two roles – reducing noise and controlling the signal – is a unique common-mode choke design. This device is available with a common-mode inductance value up to 130 nH. The unique copper windings used in the PL8209’s design form an efficient L-C resonance circuit, which is the key to its effectiveness in reducing noise. The copper windings also play a critical role in the limitation of signal frequency, ensuring data transmission is kept within a specific range.

Features of the PL8209 Common Mode Chokes

equipped with a wide operating temperature range of -40℃ to +125℃, the PL8209 features extremely low ESR (equivalent series resistance) values of 0.6Ω maximum, making it ideal for use in high-speed communications systems. In addition, its high operating frequencies (up to 400MHz) and extreme precision voltage breakdowns make the PL8209 an ideal choice for both linear and nonlinear applications. Finally, due to its simple and easy-to-install design, no special equipment is necessary for installation and maintenance.

Conclusion

The PL8209 is a custom-designed common mode choke designed to reduce noise and control signal transmission from components. Its common-mode inductance levels up to 130 nH, low ESR values of 0.6Ω, and wide operating temperature range make it a great choice for a wide range of applications, from automotive and industrial to embedded/RF applications. In addition, its easy installation and maintenance make thePL8209 an ideal choice for any project that requires signal transmission between components.
