What impact does the operating temperature range of Fakra cables have on their electrical performance?

The impact of the operating temperature range of Fakra cables on electrical performance is mainly reflected in the following aspects:

Transmission loss: In low-temperature environments, the resistance of metal conductors inside cables increases, and the dielectric constant of insulation materials may also change, resulting in increased signal transmission loss and weakened signal strength. At high temperatures, the performance of insulation materials may decrease, leading to leakage and other issues. This can also increase transmission losses and affect signal quality. For example, when a car is driving at high speeds through cold areas, using Fakra cables for a car radio may result in increased signal noise.

Characteristic impedance: Temperature changes can cause changes in the physical dimensions and material properties of cables, resulting in changes in characteristic impedance. When the characteristic impedance does not match, it can cause signal reflection, reduce signal transmission efficiency, and in severe cases, may lead to signal distortion. In car navigation systems, GPS signal positioning may be inaccurate.

Signal delay: Temperature changes can affect the propagation speed of signals in cables, leading to signal delay. In some applications that require high time synchronization, such as ADAS systems in automobiles, signal delay may affect the real-time processing of environmental information around the vehicle, reducing the system's response speed and accuracy.
