The **031-220N-RFX** is a specific type of high-frequency RF (Radio Frequency) connector. It is part of the **BNC (Bayonet Neill–Concelman)** family, manufactured by **Amphenol RF**. --- ## 1. Component Specifications The following table summarizes the key electrical and mechanical characteristics of the 031-220N-RFX: | Feature | Specification | | :--- | :--- | | **Connector Type** | BNC Jack (Female) | | **Body Style** | Straight, Bulkhead | | **Termination Type** | Solder Cup | | **Impedance** | 50 Ohms | | **Frequency Range** | 0 - 4 GHz | | **Voltage Rating** | 500 Volts Peak | | **Insulation Resistance** | 5000 MΩ (Minimum) | | **Body Material** | Brass | | **Body Plating** | Nickel | | **Contact Plating** | Gold | --- ## 2. Key Electronic Features * **Bulkhead Mounting:** This part is designed to be mounted through a hole in a panel or enclosure. It usually comes with a hex nut and a lock washer to secure it firmly against the chassis, providing a grounded connection to the panel. * **Solder Cup Termination:** Unlike crimp-style connectors used for cables, the "Solder Cup" allows a discrete wire to be soldered directly to the center contact. This is ideal for internal box-to-external interface wiring. * **Constant Impedance:** Rated at **50 Ohms**, it is optimized for standard RF equipment, ensuring minimal signal reflection and power loss within its 4 GHz operating range. * **Bayonet Locking:** Features the classic two-stud bayonet coupling mechanism, allowing for rapid connection and disconnection without tools. --- ## 3. Common Applications Due to its robust design and ease of installation, the 031-220N-RFX is frequently used in: 1. **Test & Measurement:** Oscilloscopes and signal generators. 2. **Telecommunications:** Base station equipment and antennas. 3. **Medical Electronics:** Imaging and diagnostic devices. 4. **Industrial Controls:** Panel-mounted signal interfaces. --- ## 4. Part Number Breakdown (RFX Series) The **RFX** suffix indicates that this is part of Amphenol’s commercial-grade line. These parts provide high performance at a lower cost compared to military-spec (MIL-SPEC) versions, making them suitable for high-volume commercial production.
