1.13 mm coaxial cable technical specs

　　Hope this email finds you well. We understand you're interested in 1.13 mm coaxial cables, and we're here to provide you with comprehensive technical specifications.

　　1. Physical Structure

　　Inner Conductor: Composed of 7 strands of 0.08 mm silver - plated annealed copper wires. This construction ensures low resistance and good electrical conductivity, which is crucial for minimizing signal loss during transmission. The silver - plating not only enhances conductivity but also provides better corrosion resistance, prolonging the cable's lifespan.

　　Dielectric: The dielectric material is PFA (Perfluoroalkoxy) with a diameter of 0.68 mm. PFA offers excellent electrical insulation properties, effectively separating the inner and outer conductors. It helps in maintaining the integrity of the electrical signal by reducing signal leakage and interference.

　　Outer Conductor: Made of silver - plated annealed copper with a thickness of 0.05 mm and a shield coverage of 95%. The high - coverage shield is vital for protecting the inner conductor from external electromagnetic interference, ensuring a clean and stable signal transmission.

　　Sheath: The outer sheath is also made of PFA with an outer diameter of 1.13 mm. PFA's chemical resistance, high - temperature stability, and mechanical durability make it an ideal choice for the sheath. It protects the internal components of the cable from environmental factors such as moisture, chemicals, and physical abrasion.

　　2. Electrical Characteristics

　　Impedance: The impedance of our 1.13 mm coaxial cable is 50 ± 3 ohm. Maintaining a consistent impedance is essential for efficient signal transfer. A well - matched impedance between the cable and the connected devices minimizes signal reflection, ensuring that the transmitted signal is effectively received.

　　Nominal Capacitance: It has a nominal capacitance of 95.6 pf/m. Capacitance affects the signal's speed and distortion. Our cable's optimized capacitance value helps in achieving high - speed and low - distortion signal transmission.

　　Velocity of Propagation: The velocity of propagation is 70% of the speed of light in a vacuum. This indicates how fast the electrical signal travels through the cable relative to the speed of light. A higher velocity of propagation is beneficial for applications where quick signal transfer is required.

　　Insulation Resistance: Our cable offers excellent insulation resistance, which prevents electrical leakage between the inner and outer conductors. This high - level of insulation is crucial for maintaining signal integrity and preventing short - circuits.

　　Inner Conductor Resistance: The inner conductor has a low resistance, ensuring that the signal strength remains high as it travels through the cable. Low resistance in the inner conductor is essential for long - distance signal transmission without significant attenuation.

　　Outer Conductor Resistance: Similarly, the outer conductor also has a low resistance, which contributes to the overall efficiency of the cable in terms of signal shielding and ground return.

　　3. Attenuation Performance

　　The attenuation of our 1.13 mm coaxial cable varies with frequency. Here are the attenuation values at different frequencies:

　　At 1000 MHz, the attenuation is 230 dB/100 m (70.1 dB/100 ft).

　　At 2000 MHz, it is 310 dB/100 m (94.5 dB/100 ft).

　　At 3000 MHz, the attenuation reaches 390 dB/100 m (118.9 dB/100 ft).

　　At 4000 MHz, it is 460 dB/100 m (140.2 dB/100 ft).

　　At 5000 MHz, the attenuation is 510 dB/100 m (155.4 dB/100 ft).

　　At 6000 MHz, it is 580 dB/100 m (176.8 dB/100 ft).

　　These attenuation values are within the industry - standard range, making our cable suitable for a wide range of applications where high - frequency signal transmission is involved.

　　4. Mechanical and Environmental Characteristics

　　Operating Temperature Range: Our 1.13 mm coaxial cable can operate in a temperature range from - 55 °C to + 180 °C. This wide temperature range makes it suitable for various environments, whether it's in extremely cold outdoor settings or high - temperature industrial applications.

　　Test Insulation Voltage: The cable has been tested to withstand an insulation voltage of 1000 V. This high - voltage resistance ensures the safety and reliability of the cable, especially in applications where high - voltage signals may be present.

　　Minimum Bend Radius: The recommended minimum bend radius of the cable is 6 mm. It's important to note this value during installation to avoid damaging the cable's internal structure, which could lead to signal degradation or cable failure.

　　Our 1.13 mm coaxial cables are of high quality and are widely used in applications such as telecommunications, aerospace, medical equipment, and high - speed data transfer systems.
