The **FL-R-PC-10** is a specialized ultra-miniature surface-mount coaxial connector, part of the **FL Series** (often associated with manufacturers like Hirose or compatible generic high-frequency components). It is primarily designed for high-frequency signal transmission in space-constrained electronic devices. --- ### 1. Key Technical Specifications The following table outlines the primary electrical and physical characteristics: | Feature | Specification | | :--- | :--- | | **Connector Type** | Coaxial Receptacle (Female) | | **Mounting Type** | Surface Mount (SMT) / PCB Mount | | **Frequency Range** | DC to 6 GHz | | **Nominal Impedance** | 50 Ohms | | **V.S.W.R.** | 1.3 Max (0 to 3 GHz) / 1.5 Max (3 to 6 GHz) | | **Mated Height** | ~0.9mm to 1.5mm (depending on mating plug) | | **Contact Plating** | Gold Plated (for low resistance and oxidation prevention) | --- ### 2. Physical Construction The FL-R-PC-10 is engineered for extreme miniaturization. Its construction involves three main parts: 1. **Center Contact:** A small gold-plated pin that carries the signal. 2. **Insulator:** Usually made of a high-performance liquid crystal polymer (LCP) or PTFE to maintain impedance and withstand soldering heat. 3. **Outer Shell/Ground:** A metal casing that provides the ground connection and acts as a shield against Electromagnetic Interference (EMI). --- ### 3. Applications Due to its small footprint and high-frequency capabilities, this part is commonly found in: * **Mobile Devices:** Smartphones and tablets for internal antenna connections. * **Wireless Modules:** Wi-Fi, Bluetooth, and GPS modules. * **IoT Hardware:** Compact sensors requiring external antenna routing. * **Wearables:** Smartwatches and medical monitoring devices. --- ### 4. Comparison with Similar Connectors The FL series is often compared to the more common **U.FL** series. While they serve similar purposes, the FL-R-PC-10 is generally used in applications requiring an even lower profile or specific automated pick-and-place requirements during PCB assembly. ---
