1.13mm Micro-Coaxial Cable

Description

The 1.13mm Micro-Coaxial cable is a high-performance RF interconnect designed for 50 Ohm systems where space is at a premium but low signal loss is still required. With a nominal outer diameter of 1.13mm, it strikes an ideal balance between the ultra-thin 0.81mm series and the slightly larger 1.32mm or 1.37mm cables. The cable features a stranded silver-plated copper center conductor, providing exceptional flexibility and mechanical endurance for routing through laptop hinges and tight enclosures.

The internal construction utilizes a high-stability FEP (Fluorinated Ethylene Propylene) dielectric and jacket, ensuring excellent thermal stability and chemical resistance. Signal integrity is maintained by a high-density silver-plated copper braided shield, which offers superior RF isolation and protection against interference. This cable is most commonly used in micro-pigtail assemblies and is the standard interface for U.FL (IPEX MHF) and MHF4 connectors in consumer electronics.

Key Technical Advantages

• Optimal Balance of Size and Loss: Provides lower attenuation than 0.81mm cables while remaining thin enough for the most compact consumer electronics.

• High Flexibility: The stranded center conductor allows for a tight bend radius and repeated movement, making it perfect for flip-top or rotating device hinges.

• High-Frequency Performance: Optimized for stable impedance and low VSWR across the 2.4GHz, 5GHz, and 6GHz bands, including WiFi 6E/7 and 5G sub-6GHz.

• Silver-Plated Signal Path: Silver plating on both the conductor and the braid maximizes conductivity and provides superior resistance to oxidation.

• Durable FEP Construction: The FEP jacket is resistant to heat and abrasion, ensuring a long operational life in high-density electronic environments.
