As electronic devices develop towards thinness, high performance, and high frequency, micro coaxial cable (极细同轴线) has become an important choice for applications such as laptops, mobile phones, VR/AR, and data centers due to its combination of ultra-fine size and excellent electrical performance. I-PEX's CABLINE®-UA II series provides high-reliability interfaces for micro coaxial cable, with the 20497-040T-30 model being a typical representative.
This article will be analyzed from three aspects: product features, coaxial structure advantages, and practical application value.
Product Introduction of I-PEX 20497-040T-30
Product positioning: CABLINE®-UA II series plug housing (plug housing), compatible with 40-pin micro coaxial cable, usually used with 20496-040T-40 cable assembly.
Physical characteristics: Contact spacing of only 0.3 mm, with a height of 1.37 mm, it can support multiple AWG #44 50Ω ultra-thin coaxial cables, with current carrying capacity of approximately 0.19 A, compact size for easy application in slim devices.
Environmental Certification: Passed RoHS, REACH and Halogen-Free (Halogen-Free) certification, covering all models of the CABLINE®-UA II series, including 20497-040T-30.
The importance of ultra-fine coaxial coaxial structures
Coaxial means having the same axis, referring to the inner conductor responsible for signal transmission, surrounded by a shielding layer formed by the outer conductor, and covered by a sheath. Its advantages include:
Excellent anti-interference ability: internal and external metal shielding effectively isolates EMI.
Stable impedance: Common 50Ω design ensures high-frequency signal matching and reduces signal reflection.
Suitable for high-frequency applications: capable of transmitting signals up to several GHz, applicable to high-speed interfaces such as eDP, USB-C, PCIe, and Wi-Fi.
Therefore, coaxial cable is not only a structural design, but also a key to stable transmission of high-frequency signals, while "micro" emphasizes its extreme thinness, which is convenient for wiring in small spaces.
III. Advantages of CABLINE®-UA II in Practical Application
Small volume: 0.3mm spacing with 1.37mm height, compatible with slim laptops, foldable phones, and AR/VR devices with limited space.
Support high-speed transmission: Complemented with micro coaxial cable, it can achieve several Gbps transmission, meeting the needs of high-definition video, data transmission, and high-speed interfaces.
3. EMI has strong anti-interference ability: multi-point grounding and metal shielding structure reduce electromagnetic interference and improve signal stability.
Reliable connection: mechanical locking design prevents loosening, suitable for mobile or industrial applications.
Environmental compliance: Meets international green manufacturing requirements through RoHS, REACH, and halogen-free certifications.
The coaxial design of extremely fine coaxial lines not only ensures signal integrity but also provides a reliable foundation for high-speed interconnect solutions.
I-PEX CABLINE®-UA II series 20497-040T-30 interface, with its compact size, high-speed transmission capability, excellent anti-interference performance, and reliable connection, is an ideal choice for modern slim electronic devices and high-speed signal applications. Understanding the coaxial structure of micro coaxial cable helps better design and application of high-speed interconnect systems.
