Common Mode Chokes are a form of electrical filters designed to reduce the amount of common mode noise that is found in electrical circuits and systems. Common Mode Chokes are used to limit the common mode introduction of electrical noise from sources such as motors, switches, and power supplies. They can also be used to limit the transmission of common mode noise into the device being controlled, resulting in more stable embedded systems performance.

The PL8803 is a high-efficiency, low-impedance common mode choke based on application of high permeability and high-performance saturation-hardened ferrite. This type of common mode choke is designed to fit into a range of board-level applications in a variety of systems including industrial, medical, automotive, and consumer electronics. The PL8803 features a wide range of capabilities, such as providing high-frequency noise rejection, EMI suppression, and providing radio frequency interference (RFI) filtering.

The core of the PL8803 is composed of a special ferrite core material with high-permeability properties, using high performance saturation-hardened ferrite. The ferrite core is also designed to reduce EMI and reduce the amount of current leakage. Additionally, the PL8803 is designed to provide noise suppression and reduce the noise associated with electrical circuits and systems.

The working principle of the PL8803 can be defined as follows: when there is a differential signal in the circuit, the current will flow through the common mode choke in opposite directions. This current will then creates a magnetic field which cancels out the differential signals and suppresses the common mode noise. Additionally, the PL8803 also works to reduce the level of electromagnetic interference (EMI) around the circuit, especially at high frequencies.

The PL8803’s wide range of capabilities makes it an ideal solution for many board-level applications. In addition to providing common mode noise suppression, it also works as an effective EMI shield for both incoming and outgoing signal paths. Its wide operating temperature range also makes it suitable for use in automotive and military applications. Furthermore, the PL8803 also provides a high-frequency noise attenuation feature, ensuring that the circuit is not adversely affected by high frequency signal noise.

In conclusion, the PL8803 is a high-efficiency, low-impedance common mode choke based on application of high permeability and high-performance saturation-hardened ferrite. It provides excellent common mode noise suppression and EMI shielding capabilities, as well as attenuation of high frequency noise. All of its features make it an ideal product for board-level applications in a variety of systems, such as industrial, medical, automotive, and consumer electronics.
