Common mode chokes are electronic components that are used for filtering, restricting and manipulating electrical signals. They are used to reduce the intensity of high frequency noise so as to limit interference to electronic devices and the surrounding environment. The PL8202NL is a common mode choke that is designed to reduce interference in a variety of applications.

This product operates in the frequency range of 47kHz to 100MHz. It can be used in both the single-ended and differential-mode applications, and its choke cores feature a unique design that enables effective suppression of both differential-mode and common-mode currents. The common mode suppression ratio is 75dB at 100MHz, and the differential mode suppression ratio is 50dB at 100MHz.

When used for differential-mode current suppression, the PL8202NL can provide effective filtering against any high-frequency noise, ensuring that the signal at the output is clean and distortion-free. In addition, the device offers excellent power efficiency, with a maximum current rating of 1mA at a low operating voltage of 3.3V.

The PL8202NL is typically used in automotive, consumer electronics, industrial, and medical applications. It is especially suitable for noise suppression in high-speed signal transmission applications, such as digital audio/video, HDMI, and USB 2.0/3.0. Its design allows for good thermal stability, allowing it to remain effective in temperature ranges between -40°C to +125°C.

The working principle of the PL8202NL is based on the principle of flux cancellation. Flux cancellation involves creating a magnetic field in the opposite direction of an existing magnetic field in order to reduce its intensity. In the case of the PL8202NL, this process is used to reduce the intensity of high frequency noise and restrict interference.

The device works by using two coils with an identical winding direction and a magnetic core between them. When a differential-mode current passes through the coils, a magnetic field is created which interacts with the magnetic core. The flux generated from this interaction is then canceled by the flux generated from the opposite winding direction, thus reducing the intensity of the noise.

The PL8202NL also features an integrated ferrite core which helps to further reduce noise, as well as a wide temperature range that allows it to be used in a variety of applications. In addition, the device can also be used in single-ended applications, where it provides an effective solution for suppressing common-mode currents ranging from 47kHz to 100MHz.

The PL8202NL is an ideal solution for reducing noise and interference in high-speed signal transmission applications. Its wide temperature range, coupled with its good power handling and high common mode rejection ratio, make it suitable for a variety of automotive, industrial, consumer electronics, and medical applications. Its effective noise suppression capabilities make it a great choice for ensuring a clean and distortion-free signal.
