What are the impact of Mini Fakra cable specifications on automotive systems?

The specifications of Mini Fakra cables have the following impact on automotive systems:

Transmission frequency and data rate: Mini Fakra cables can support application frequencies up to 20GHz. It is very important for the advanced driving assistance system (ADAS), auto drive system and high-resolution information entertainment system.

Characteristic impedance: If the characteristic impedance of Mini Fakra cable does not match, it will cause signal reflection, reduce transmission efficiency, and deteriorate signal quality. In the RF communication system of automobiles, such as GPS navigation, V2X communication, etc., accurate matching of characteristic impedance is crucial to ensure effective signal transmission and reception, improve communication stability and reliability, reduce signal interference and bit error rate.

Wire diameter and size: Mini Fakra cables are thinner and lighter than traditional coaxial cables, which allows them to better adapt to the narrow space and complex wiring environment inside cars, making them easy to install and layout in vehicles, especially suitable for dense circuit boards and other size limited applications. At the same time, a smaller wire diameter also helps to reduce the weight of vehicles, which is in line with the development trend of automotive lightweighting.

Insulation resistance: Insulation resistance reflects the insulation performance of a cable. The higher the insulation resistance value, the better the insulation effect of the cable, and the smaller the possibility of leakage. It can effectively prevent safety issues such as short circuits and leakage in the electrical system, ensuring the safe operation of the automotive electrical system.

Shielding performance: Mini Fakra cables typically have good shielding performance, effectively preventing electromagnetic interference (EMI) and electromagnetic radiation (EMR). Inside the car, there are various electronic devices and wiring harnesses that may generate electromagnetic interference with each other. The shielding layer of Mini Fakra cables can isolate the signals transmitted internally from external electromagnetic interference, while also reducing the electromagnetic radiation of internal signals to the outside world, avoiding interference with other electronic devices, and ensuring the electromagnetic compatibility (EMC) of automotive electronic systems.
