The HFL-113/50-TT micro coaxial cable is a highly versatile, budget-friendly 50 Ohm RF cable designed for massive consumer electronics production and internal antenna interconnects. Constructed with a 1.13mm outer diameter, this flexible micro coaxial wire incorporates a tinned copper stranded core (7/0.083mm) wrapped in high-grade Fluorinated Ethylene Propylene (FEP) insulation, delivering reliable electrical performance and ease of processing across frequencies up to 6 GHz.
Featuring a 90% coverage tinned copper braid shield, the HFL-113/50-TT balances effective electromagnetic shielding with lower manufacturing costs compared to silver-plated alternatives. Its superior solderability makes it the ideal candidate for automated termination with IPEX MHF, Hirose U.FL, and PCB solder pads in Wi-Fi routers, smart home gadgets, and wireless telemetry hardware. HiFlexlink provides consistent batch-to-batch impedance control (50 ± 2 Ohm) and complete OEM micro-coaxial cable assembly services.

Frequently Asked Questions about HFL-113/50-TT
What is the main advantage of choosing HFL-113/50-TT over silver-plated 1.13mm cable?
HFL-113/50-TT uses a tinned copper inner conductor (TT), which offers significantly better cost-efficiency and easier soldering properties during automated mass production, making it ideal for budget-sensitive consumer antenna projects.
How does 1.13mm HFL-113/50-TT compare to 1.37mm micro coaxial cable?
The 1.13mm outer diameter is roughly 18% thinner than 1.37mm cable. It fits smaller connector crimp barrels (like Hirose U.FL or IPEX MHF) and is easier to pass through tiny hinge mechanisms in laptops and flip-shell devices.
Is HFL-113/50-TT compatible with standard IPEX MHF and Hirose U.FL connectors?
Yes. The 1.13mm outer diameter is the classic industry-standard size for IPEX MHF I / Hirose U.FL micro RF connectors, ensuring a reliable crimp and tight strain relief.
Can HiFlexlink provide pre-cut lengths and terminated assemblies of HFL-113/50-TT?
Absolutely. HiFlexlink offers custom cutting, automated stripping, tin dipping, and full connector crimping according to your engineering drawings.
