As electronic products continue to trend towards thinness and miniaturization, ultra-fine coaxial cables (Micro Coaxial Cable) have gradually become the preferred signal connection wire materials for the internal circuits of various precision equipment, thanks to their unique structure and excellent performance. So, what is ultra-fine coaxial cable? What are its core advantages? This article will give you a comprehensive analysis.
What is ultra-fine coaxial cable?
Extremely thin coaxial cables are a type of precision coaxial cable with extremely small diameters, usually ranging from 0.2mm to 1.37mm in outer diameter. The internal structure still maintains a typical coaxial structure——center conductor, insulation layer, shielding layer, and outer sheath arranged coaxially. They are widely used in scenarios with extremely high space requirements and stringent signal transmission performance requirements, such as medical endoscopes, ultrasonic probes, laptops, smartphones, drones, monitoring equipment, and wearable devices.
Detailed illustration of ultra-fine coaxial structure:
Center conductor: usually made of silver-plated copper or copper alloy
Inner insulator: high-performance polymers, such as FEP, PFA
Woven shielding layer: silver-plated copper wire or tin-plated copper wire
• Outer sheath: thermoplastic or polyurethane
The core advantages of ultra-fine coaxial lines
Extremely small diameter, occupying very little space
The fine line diameter makes it very suitable for electronic products with limited internal space.
Excellent signal transmission performance
Even with extremely thin wire diameter, it still has good high-frequency signal transmission capability, effectively reducing signal loss and interference, ensuring stable data transmission.
Excellent flexibility and bendability
Extremely thin coaxial cables are soft and easy to bend, capable of adapting to complex internal wiring in equipment, and their bend fatigue life can reach tens of thousands of times.
Strong electromagnetic shielding effect
Multi-layer shielding design effectively resists electromagnetic interference, ensuring stable signal quality.
Reliable high temperature and corrosion resistance properties
Using high-temperature polymer insulation and sheath, it can be used for a long time in complex environments such as high temperatures and humidity.
Extremely thin coaxial cables, with features such as "small diameter, high performance, strong shielding, high temperature resistance, and ultra-softness," have become an indispensable key component for signal transmission in high-end medical equipment, intelligent wearable devices, 5G terminals, and drones and other high-tech products. As electronic products continue to become thinner and more miniaturized, their application prospects will also become broader.
