Common Mode Chokes

Common mode chokes are a type of electrical filter that impedes common-mode noise from power lines. The PL8201NL is a common mode choke designed to suppress common-mode currents in ±24V power supplies, reducing noise in electrical systems. This device is ideal for applications with strict EMC performance requirements, such as industrial and military applications.

PL8201NL Application Field and Working Principle

The PL8201NL common mode choke is suited for a wide range of applications, including AC/DC converters, DC/DC converters, DC/AC inverters, and Class D audio amplifiers. It is designed to effectively reduce common-mode noise in a compact package. The PL8201NL is especially well-suited for applications in harsh environments, where high levels of electromagnetic radiation can interfere with circuits.

The PL8201NL utilizes power line common-mode chokes, also known as EMI filters, to reduce common-mode voltages and currents in power lines. The device works by providing an impedance to common-mode noise on the power line. This impedance is created by an inductor, a high-frequency disc capacitor, and a varistor. The inductor traps the high frequency noise, while the high-frequency disc capacitor blocks the high-frequency components of the current. The varistor serves as an adjustable resistor that can be used to limit the amount of current the filter can handle. This effectively limits the amount of noise that can travel on the power line.

The PL8201NL is designed to reduce differential-mode noise along with common-mode noise. The device works to eliminate both types of noise by placing an impedance between the power line and the ground, creating what is known as a common-mode choke filter. The filter will effectively suppress both the common-mode and the differential-mode noise in power lines.

The PL8201NL is capable of operating at temperatures between -40°C and +85°C, making it well-suited for a wide range of environmental conditions. The device also meets the requirements of RoHS, EMI/RFI, and other safety certifications, making it suitable for use in industrial and military applications. Additionally, the PL8201NL is compliant with the CE safety standards.
