Shanghai Bing Wire & Cable Co., Ltd

Product Introduction
Bing SR and SFT Series Semi-Rigid Coaxial Cables are high-performance, near-ideal coaxial solutions for RF and microwave engineering. These cables are available in a wide range of impedances (50Ω, 10Ω, 15Ω, 25Ω, 75Ω, 100Ω) and outer diameters from 0.50mm to 9.90mm, with a maximum continuous length of 30 meters. The outer conductor can be made of copper, aluminum, or stainless steel, with optional plating layers per customer requirements. These semi-rigid cables serve as direct equivalents to popular international specifications, making them the preferred choice for demanding RF/microwave applications.


Core Features
1. Low & Ultra-Low Loss Performance: 50Ω semi-rigid cables reduce attenuation by up to 20%, with an extended operating temperature range up to 250°C.
2. High-Temperature Resistance: "DS" high-precision semi-rigid cables withstand 150°C for 1-hour high-temperature testing, preventing copper tube cracking or bulging.
3. Customizable Solutions: Non-magnetic options available for MRI and sensitive environments; Tailored solutions for specific inner conductor strength and bending radius requirements
4. Wide Impedance & Size Range: Impedance options from 10Ω to 100Ω, with outer diameters ranging from ultra-miniature 0.50mm to high-power 9.90mm.
