Micro Coaxial Cable-Micro Coaxial Cable factory-(FRS)-FRS
If you’re researching cables, especially for audio/video, networking, or electronics projects, you’ve likely encountered both “coaxial cable” and “micro coaxial cable.” They sound similar, and they are! But understanding their key differences is crucial for choosing the right cable for your specific needs. Let’s break down micro coaxial vs coaxial cable.
The Short Answer: Micro coaxial cable is a smaller, thinner, specialized version of standard coaxial cable. While they share the same fundamental coaxial structure (center conductor, insulator/dielectric, shield, outer jacket), the primary differences lie in their size, signal capacity, power handling, flexibility, and typical applications.
| Feature | Standard Coaxial Cable | Micro Coaxial Cable | Key Takeaway |
|---|---|---|---|
| Size | Larger diameter (e.g., 5-10mm common) | Significantly smaller (e.g., < 3mm) | Micro coaxial wins where space is critical. |
| Conductor/Shield | Relatively thicker core & shield | Extremely thin core & shield layers | Standard coax offers structural robustness. |
| Signal Capacity | Excellent for moderate-high frequencies | Designed for very high frequencies | Both can handle high frequencies, but micro coax excels in modern high-bandwidth/miniature apps. |
| Power Handling | Can handle significant power | Very limited power handling | Standard coax necessary for antenna feeds/other power transmission. |
| Flexibility | Moderately flexible (depends on type) | Highly flexible | Micro coax is ideal for tight bends/moving parts. |
| Impedance | Typically 50 Ohm (RF) or 75 Ohm (AV) | Most commonly 50 Ohm | Match impedance to your equipment! Crucial for both types. |
| Key Applications | Cable TV/Internet feeds, Antenna connections, RF test equipment, Professional A/V | Internal device wiring (cameras, laptops, mobiles), Miniature RF connectors, High-density interconnects, Thin displays | Standard coax: Infrastructure & power. Micro coax: Internal electronics & miniaturization. |
Imagine a cable built like a shield around a messenger. Standard coaxial cable (often shortened to “coax”) has this core structure:
Why is it great? This design creates a highly controlled “waveguide” for the signal. Electromagnetic fields carrying the signal are largely confined between the center conductor and the shield. This results in:
Where You See Standard Coax:
Common sizes range from a few millimeters (like RG174) up to over a centimeter in diameter. Flexibility varies greatly depending on type (solid core vs stranded core, braid density).
Micro coaxial cable (often abbreviated to “µCoax” or “micro coax”) takes the coaxial design principle and shrinks it dramatically. It has the exact same components:
BUT, everything is manufactured on a much smaller scale with specialized, ultra-thin materials.
Why was it created? The driving force is miniaturization. As electronic devices shrank (think smartphones, digital cameras, laptops, drones, wearables), the bulky connectors and cables used inside became a major constraint. Micro coax solved this problem for high-frequency signals.
