Common Mode Chokes are electronic components used to suppress common mode noise on communication lines. The RD7147-36-0M2 series is a common mode filter for automotive applications, which is designed to reduce electromagnetic interference (EMI) and electrostatic discharge (ESD) that can cause communication errors. It is an advanced shield module that combines an inductor with a capacitor in a three-layer printed circuit board (PCB) for fast response.

The RD7147-36-0M2 series filter is suitable for automotive communication control in CAN, LIN, Ethernet, and infotainment systems. It offers superior ESD protection over competitors and reduces EMI on signal lines. This reduces the risk of signal corruption due to noise interference and protects the signal integrity of the automotive communication system.

The RD7147-36-0M2 series is designed to provide strong common-mode suppression over a wide frequency range from DC to 2MHz. It has a low cut-off frequency of 1.0 MHz and a high cut-off frequency of 2.0 MHz. This ensures that the device can block any noise due to ESD, EMI and other sources. The RD7147-36-0M2 also has a low insertion loss and high signal transmissibility, which minimises signal distortion. Furthermore, it is designed to withstand a high surge current to enable the module to meet the requirements of automotive applications.

The RD7147-36-0M2 common mode filter consists of a three-layer printed circuit board with two inductors and one capacitor. The inductor and the capacitor are arranged in a way such that the signal moves along the inductor, while the capacitor blocks any external noise coming in. The device operates on a principle called high-frequency impedance transformation. When the signal is passed through the inductor and capacitor, the high-frequency signal is reduced and the low-frequency signal is unaffected. This reduces the EMI and ESD interference from the signal, while maintaining the signal integrity.

The RD7147-36-0M2 can be used in a wide range of automotive electronic systems, such as powertrain control modules, body control modules, and infotainment systems. It is also suitable for the protection of critical data signals, such as CAN bus, Ethernet, LIN bus, and other high-speed communication. The device is RoHS compliant and is supplied in surface mount packages.

The RD7147-36-0M2 common mode filter offers effective EMI and ESD protection for automotive communication systems. It has a wide frequency range and provides strong common mode suppression. The filter has low insertion loss and a high signal transmissibility, and can withstand high surge current. It is suitable for a wide range of automotive electronics systems and is RoHS compliant.
