The HFL-083L micro RF coaxial cable is an ultra-fine, precision 50 Ohm coaxial wire specifically designed for space-critical and non-magnetic signal routing. Featuring a sub-millimeter outer diameter of just 0.83mm, this ultra-miniature cable incorporates a silver-plated copper stranded conductor (7/0.06mm) and high-grade Fluorinated Ethylene Propylene (FEP) insulation, delivering reliable electrical stability and low signal attenuation in extremely confined spaces.
Engineered with a dense silver-plated copper braid shield, the HFL-083L provides effective electromagnetic shielding without adding rigid bulk. Its low-magnetic construction makes it the specialized cable of choice for medical MRI coil repair, endoscopic diagnostic tools, ultra-thin laptop hinges, and wearable RF telemetry. HiFlexlink maintains strict 50 ± 3 Ohm impedance control and offers fully customized OEM micro-coaxial cable jumper assemblies fitted with IPEX MHF4, Hirose W.FL, or custom solder terminals tailored to your exact application specs.

Frequently Asked Questions about HFL-083L
What is the primary difference between HFL-083L and other 50 Ohm cables?
HFL-083L features an ultra-thin 0.83mm outer diameter using silver-plated copper inner conductor (7/0.06mm composition) and FEP insulation, making it specifically optimized for high-frequency micro-RF signal transmission where space and weight are critical constraints.
How does 0.83mm HFL-083L compare to 1.13mm or 1.37mm micro coax cables?
HFL-083L is significantly smaller, reducing the outer diameter to 0.83mm. This allows it to fit into sub-miniature connectors like IPEX MHF4/MHF5 and Hirose W.FL, whereas 1.13mm and 1.37mm cables are too thick for these micro connector barrels.
What connectors are compatible with the 0.83mm HFL-083L cable?
It is specially sized for fourth and fifth generation micro RF connectors, including IPEX MHF IV (MHF4), IPEX MHF5, Hirose W.FL, and micro-solder pads on high-density PCBs.
Can HiFlexlink customize the length or connector terminals for HFL-083L?
Yes. HiFlexlink provides complete OEM/ODM services, offering precision pre-cut lengths, micro-stripping, automated tinning, and factory-tested connector crimping according to your engineering drawings.
