Small in size, great in capability: Vehicle-grade ultra-fine coaxial cable束powers the intelligentization of automotive electronics

Under high-frequency transmission, the full analysis of loss control for extremely thin coaxial cable harnesses is of great significance. With the rapid development of automotive electronics and intelligent technology, signal transmission within the vehicle is no longer limited to traditional power distribution, but has evolved towards high-bandwidth communication with high-speed data and high-definition images. Against this backdrop, vehicle-grade extremely thin coaxial cable harnesses (Micro Coaxial Cable Harness) have emerged and become one of the indispensable core components of intelligent vehicles.

Automotive grade ultra-fine coaxial cable assembly
"Vehicle-grade ultra-fine coaxial cable assembly" can be divided into three key concepts:
Automotive-grade
Products representing the automotive electronics industry's strict standards (such as AEC-Q series certifications) can operate stably for a long time in harsh environments such as high temperatures, strong vibrations, humidity changes, and electromagnetic interference.
Ultra-fine coaxial cable
It is a coaxial cable with an extremely small diameter (usually 0.2mm～1mm), consisting of a central conductor, insulating layer, shielding layer, and outer sheath, which can achieve stable transmission of high-speed signals in narrow spaces.
Cable harness
A cable assembly that integrates multiple extremely thin coaxial cables into a complete signal channel through processing and connector assembly.
In short, the automotive-grade ultra-fine coaxial cable assembly combines high-frequency transmission performance with automotive-grade reliability, and is a precision interconnect solution specifically designed for automotive high-speed signal systems.

High-density and high-performance parallel
Extremely thin coaxial cables are known for their minimal outer diameter and precise structure, making them suitable for vehicle environments that are space-constrained and require high signal integrity. Their multi-layer structure, including the central conductor, insulating medium, shielding layer, and outer sheath, is designed and controlled with precision to ensure excellent electromagnetic compatibility and signal integrity.
Common characteristic impedance is 45Ω or 50Ω, which can meet the application requirements of high-definition video, radar sensors, and high-speed data interfaces.

Excellent anti-interference ability
Compared with traditional wiring structures, ultra-fine coaxial cable bundles have obvious advantages in anti-interference. Each wire has an independent shielding layer, which can effectively resist external electromagnetic interference (EMI). Even in the complex interference environment of vehicle-mounted motors, control units, and radar signals, it can maintain stable signals. This feature is crucial in automotive applications, ensuring the reliable operation of key modules such as cameras, surround-view systems, and ADAS.

Four, wide application and environmental adaptability
Automotive-grade ultra-fine coaxial cable assemblies are widely used in:
Car-mounted high-definition camera and surround-view system
Intelligent cabin display and information entertainment system
Advanced Driver-Assistance Systems (ADAS)
Autonomous driving sensors and control module
In addition, its lightweight, high flexibility, and resistance to bending make it also suitable for medical imaging equipment, industrial testing instruments, and consumer electronic products that require extremely high signal quality.

Five, support for future high-speed interfaces
As high-speed interfaces such as USB4, Thunderbolt, and PCIe gradually enter the automotive application field, data transmission speeds are constantly improving. Automotive-grade ultra-thin coaxial cable bundles, with their characteristics of low loss, low delay, and precise impedance matching, can support data rates of up to tens of Gbps, providing stable and high-speed signal channels for autonomous driving systems and in-car entertainment.

Automotive-grade ultra-fine coaxial cable harnesses are becoming the core interconnection solution for intelligent automotive electronic systems due to their compact size, excellent anti-interference capability, and high-speed transmission characteristics. They not only enhance the reliability of the in-vehicle signal chain but also lay a solid foundation for future more complex electronic architectures and autonomous driving systems.
