Key Features of the SMA-KFD189 HUADA Coaxial Connector
Electrical Data:
Impedance: The SMA-KFD189 operates at 50Ω, ensuring optimal signal integrity.
Interface Frequency (max): It supports frequencies up to 18 GHz, making it suitable for high-speed applications.
VSWR (Voltage Standing Wave Ratio): The VSWR is impressively low, with a maximum value of ≤1.05 + 0.01×f(GHz). This means minimal signal reflection and efficient power transfer.
Voltage Rating: The connector can handle up to 500 V(rms).
Test Voltage: It has been tested and proven safe at 1000 V(rms).
Contact Resistance:
Center Conductor: The center conductor’s contact resistance is ≤3 mΩ, ensuring reliable signal transmission.
Outer Conductor: The outer conductor maintains excellent insulation resistance of ≥5000 MΩ.
Mechanical Data:
Weight: The SMA-KFD189 weighs only 2.3 grams, making it lightweight and easy to handle.
Durability: Designed for longevity, it withstands 500 mating cycles without compromising performance.
Environmental Data:
Operating Temperature: The connector operates reliably across a wide temperature range, from -65°C to 165°C. Whether in extreme cold or heat, it remains dependable.
Material Data:
Body Material: The connector body is made of brass, with a gold plating of 0.2 μm over nickel (2.0 μm). This ensures corrosion resistance and durability.
Center Contact Material: The center contact is crafted from beryllium copper, with a gold plating of 0.5 μm over nickel (2.0 μm). This combination provides excellent conductivity.
Insulator Material: The insulator is composed of PTFE (Polytetrafluoroethylene), known for its high dielectric strength and low loss.
