In the current trend of miniaturization, lightweighting, and high-speed signal transmission in electronic devices, this "invisible hero" is quietly evolving. Perhaps you haven't noticed, but there is a super thin coaxial cable with a diameter of only 0.2mm in your smartphone, drone, medical equipment, and even smart wearable devices. So, how strong is this super thin wire material? Let's explore the truth through real data!
What is a 0.2mm ultra-fine coaxial cable?
Extremely fine coaxial cables (0.2mm) are a typical type of coaxial cable structure, consisting of an inner conductor, insulation layer, outer conductor, and sheath arranged concentrically. As the name implies, its outer diameter is only 0.2mm, slightly thicker than a hair strand (about 0.07mm), but it can transmit high-definition video, high-speed data, and even withstand repeated bending. It is widely used in applications that require extremely high space and weight, such as smartphone cameras, endoscopes, and drone image transmission.
Secondly, let's look at the actual test data to see how strong it really is!
• Tensile strength: The tensile strength of a single 0.2mm coaxial cable is ≥ 25N, which means a thin thread can lift a load of about 2.5 kilograms, comparable to a bottle of mineral water!
Bend life: Under ±90° bending and a 30mm bending radius, it can withstand more than 100,000 bends without breaking and maintain stable signal transmission.
Impedance stability: Typical impedance of 50Ω±5Ω, differential signal rate up to 6Gbps, ensuring smooth and uninterrupted video transmission for high-definition cameras or drone imagery.
High temperature resistance: Continuous resistance to 125°C, short-term resistance to 150°C, suitable for complex high-temperature environments.
• Shielding effect: High-density silver-plated copper braiding + aluminum foil shielding, shielding effect ≥ 90dB, strong anti-interference, ensuring high-speed signal does not drop frames.
Application scenarios, strength as evidence
0.2mm ultra-fine coaxial cables have been widely used in:
• Phone camera module internal wiring
Drone transmission system
Medical endoscope
TWS earphone battery connection line
This extremely fine coaxial cable not only achieves the ultimate thinness but also takes into account high strength, long service life, high-speed transmission, and anti-interference capability. With the continuous development of the 5G, AIoT, intelligent medical, and drone industries, the application scenarios of 0.2mm ultra-fine coaxial cables will become more and more numerous, and they may appear in more unexpected devices in the future.
