    INTRODUCTION

    The SMB Straight Plug Crimp Connector for RG178U cable is precision-crafted for cable applications.

    With standard 50Ω impedance and a frequency range of 0-4 GHz, VSWR of 1.22 max and insertion loss of 0.2 dB, it excels at maintaining signal integrity and reliability, achieving optimal signal transmission across various applications.

    For seamless installation, we recommend assembling the center contact to the cable inner conductor via soldering. Additionally, crimp the ferrule onto the cable to ensure secure connections for transmission and fixation, providing robust and lasting connections.

    For durability and exceptional performance, the connector body is manufactured from high-quality brass and beryllium copper, ensuring stability and longevity. Beryllium copper center contact ensures superior electrical conductivity and reliability. PTFE insulation further enhances connector durability and electrical performance.

    With 335V rms working voltage at sea level and 750V rms dielectric withstanding voltage, insulation resistance of 1000 Megohms ensures consistent electrical performance under various conditions.

    Maintaining low contact resistance—center contact resistance below 6.0 milliohms, outer contact resistance below 1.0 milliohms. The connector handles up to 220W power, suitable for applications with higher power requirements.

    Designed for reliability, this SMB connector withstands 500 mating cycles. The construction allows cable retention requiring minimum 6 lbs force, with center contact retention requiring minimum 4 lbs axial force for secure and stable connections.

    Operating seamlessly across temperatures from -65°C to 165°C, this SMB connector suits diverse environmental conditions. Compliant with stringent quality standards including MIL-STD-202 Method 204 Condition B for vibration and MIL-STD-202 Method 101 Condition B for salt spray testing.

    Enhance your connectivity performance with the SMB Straight Plug Crimp Connector, delivering exceptional performance and reliability for communication requirements.
