Common Mode Chokes are a type of transformer based electrical passive device used to reduce unwanted electromagnetic interference (EMI). They are typically used for filtering or “choking” common-mode currents (currents that flow between two points on a circuit) generated by digital circuit switching and radio-frequency (RF) applications. Common mode chokes are deployed in many different applications, such as DC power circuits, telecommunications, and industrial systems where they are used to prevent noise from propagating further down the power supply.

The PE-65950 is a specific type of common mode choke designed to filter out unwanted noise from high-speed applications, such as Ethernet cables, as well as digital signal lines in industrial settings. It is constructed with two cores inserted within a single, common, ferrite toroid. The cores are connected by two windings; one winding is used to block common mode noise, while the other is used to pass DC and single-ended signal currents while blocking the common mode noise. The combination of the two core windings creates a differential filter, helping to reduce EMI noise in the resulting signal.

The PE-65950 is especially useful for applications where there are both power and signal lines in a circuit that intersect and can cause interference. Due to its efficient design, this type of common mode choke allows for a significant reduction in electromagnetic interference and subsequent improvement in the quality of the transmitted signal. In addition, the PE-65950 is constructed from a variety of materials for a range of mechanical and electrical properties, making it well suited for selection in a variety of industrial and commercial settings.

The core of the PE-65950 is constructed from ferrite, which is a type of magnetic ceramic composed of iron oxide and other metal oxides. The material is chosen for its high electrical resistivity, allowing it to act as an effective filter for noise. It also has low power dissipation, allowing it to tolerate higher levels of power and heat without failure. Additionally, the PE-65950 is equipped with a 130°C rated insulation system composed of polyamide-imide (PAI)-tape, providing added protection against shorting and safeguarding the device.

The working principle of the PE-65950 is relatively straightforward: the common mode choke works by blocking common-mode currents while allowing the passage of differential signal currents. The common mode choke does this by interrupting the flow of common-mode currents between the two connected cores. The resulting differential filter works to eliminate the common mode noise and to allow a more accurate signal transmission.

The PE-65950 is used to reduce unwanted EMI in a variety of applications. Particularly, they are utilized in telecom systems, radar systems, DC motors, and other motor systems, digital data signal lines, and networks. The choke produces a differential filter that helps to reduce the amount of noise that could pass through. This helps to ensure a more reliable and accurate signal is transmitted.

Overall, the PE-65950 is a highly effective common mode choke for a variety of different applications. It is designed to suppress common-mode currents, which can interfere with signal transmission in a number of ways. The device is constructed with two cores within a single ferrite toroid, providing both a low power dissipation and an efficient differential filter for noise reduction. The PE-65950 is used widely in many industries, ranging from telecoms to radar systems, providing a highly effective EMI reduction, and the assurance of a reliable and accurate signal transmission.
