Key Features of the SMA-KFD80 Coaxial Connector

Impedance: The SMA-KFD80 has an impedance of 50Ω, which ensures efficient signal transmission.
Interface Frequency (max): It operates up to 18 GHz, making it suitable for high-frequency applications.
VSWR (max): The Voltage Standing Wave Ratio is impressively low, with a maximum of 1.05 + 0.01×f(GHz). This minimizes signal loss.
Voltage Rating: It can handle up to 500 V(rms) safely.
Test Voltage: The connector withstands 1000 V(rms) during testing.
Contact Resistance: Center Conductor: The center conductor’s contact resistance is ≤3 mΩ. Outer Conductor: The outer conductor maintains excellent insulation resistance (≥5000 MΩ).
Weight: The SMA-KFD80 weighs 3.4 grams, making it lightweight and easy to handle.
Durability: It can withstand 500 mating cycles, ensuring long-lasting performance.
Operating Temperature: The connector operates reliably in a wide temperature range, from -65°C to 165°C.
Body: Made of brass with a gold plating (0.2 μm over nickel 2.0). This ensures corrosion resistance.
Center Contact: Beryllium copper with gold plating (0.5 μm over nickel 2.0) for optimal conductivity.
Insulator: The insulator material is PTFE (Polytetrafluoroethylene), known for its high dielectric strength.
