Common Mode Chokes are passive electrical devices that are used to block or attenuate common mode signals on a data or computer bus system. They are typically found in power supplies, Ethernet cables, and other data communication systems where common mode signals often occur. The ET2432-020 is a specific type of Common Mode Choke designed for automotive applications.

The ET2432-020 uses a unique combination of magnetically bonded Toroidal materials along with proprietary cores to generate a self-resonating effect, which increases its inductance and helps suppress common mode noise. It is designed to operate within the frequency range of 150kHz to 25MHz, and can perform as both an AC and a DC-coupled filter. The choke also features a very low DCR, or resistance, which ensures minimal signal degradation.

The ET2432-020 is designed to provide a cost-effective solution that meets the requirements of automotive EMC regulations worldwide. It has been tested and certified to meet the requirements of ISO 16750-2, along with several other global automotive standards. It is also RoHS and REACH compliant.

The ET2432-020 can be used to attenuate or reject any type of common mode noise on a data or computer bus system, such as in an automotive system or a home network. It is a very effective device for filtering out EMI noise, and can be used to reduce the effect of crosstalk between different data lines.

The working principle of the ET2432-020 is fairly straightforward. It works by creating a 3-terminal choke that effectively blocks or attenuates unwanted common mode signals. This is accomplished through the use of two separate core materials, which are magnetically bonded together to form a self-resonating effect. The core materials act as a high-impedance barrier against the common mode signals, while allowing signals to pass through them without ill effect. The two core materials also create a distributed capacitance across the choke, which helps to minimize changes in the inductance as the operating frequency changes.

In summary, the ET2432-020 is a type of Common Mode Choke designed specifically for automotive applications. It is designed to provide a cost effective solution for suppressing common mode noise on a data or computer bus system. It features a low DCR, or resistance, and operates over a wide frequency range. It has been certified to meet the requirements of ISO 16750-2, as well as several other global automotive standards. The ET2432-020 is very effective at attenuating or rejecting unwanted common mode signals, and is a great choice for automotive EMC systems where limiting crosstalk is essential.
