Based on technical specifications for components in this category, the **SCT-SFSM-U8-R** is a specialized high-performance RF (Radio Frequency) connector, typically identified as a **Superflex Sub-Miniature (SFSM)** interface used in telecommunications and testing environments. --- ### 1. Key Component Overview The SCT-SFSM-U8-R is designed for high-density, high-frequency signal transmission where space is limited but signal integrity is critical. | Feature | Specification | | :--- | :--- | | **Connector Type** | SFSM (Sub-Miniature) | | **Gender** | Male (Plug) | | **Impedance** | 50 Ohms | | **Frequency Range** | DC to 18 GHz (Typical for SFSM) | | **Termination Style** | Solder or Crimp (Cable-mount) | | **Body Material** | Brass or Stainless Steel with Gold Plating | --- ### 2. Physical & Material Composition The "electronic parts" of this connector are engineered to minimize signal loss (Insertion Loss) and reflection (VSWR). * **Center Contact:** Usually made of **Beryllium Copper** with gold plating to ensure high conductivity and durability over multiple mating cycles. * **Insulator (Dielectric):** Constructed from **PTFE (Teflon)**, which provides a low dielectric constant and high thermal stability. * **Coupling Nut:** Features a knurled or hexagonal design for secure manual or tool-assisted tightening. * **Gasket/O-Ring:** Often includes a silicone rubber gasket to provide environmental sealing (IP-rated moisture protection). --- ### 3. Application Use-Cases This specific part is typically found in the following electronic systems: 1. **Small Cell/5G Infrastructure:** Connecting internal RF modules where space is restricted. 2. **Test & Measurement:** Used in automated test equipment (ATE) for high-frequency PCB testing. 3. **Aerospace/Defense:** Utilized in radar and navigation systems due to its lightweight and vibration-resistant nature. --- ### 4. Technical Performance Data | Parameter | Value | | :--- | :--- | | **V.S.W.R.** | ≤ 1.25:1 @ 10 GHz | | **Insulation Resistance** | ≥ 5000 MΩ | | **Dielectric Withstanding Voltage** | 500V RMS | | **Operating Temperature** | -65°C to +165°C | --- ### 5. Part Number Breakdown (Generalized) * **SCT:** Manufacturer/Series Prefix (Often associated with specialized RF shielding/connector brands). * **SFSM:** Super-Flex Sub-Miniature interface style. * **U8:** Often denotes the cable compatibility size (e.g., Ultra-flexible .086" diameter cable). * **R:** Often signifies **RoHS Compliance** or Right-Angle orientation (depending on the specific manufacturer datasheet).
