The **REB-C4-R** is an electronic component primarily classified as a **High-Frequency Connector** or a specific **Board-to-Board/Interface** component, depending on the manufacturer (most commonly associated with connector series used in communication modules). Below is a breakdown of its technical specifications and electronic properties. --- ### 1. General Specifications | Feature | Details | | :--- | :--- | | **Component Type** | Connector / Interface Header | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Contact Material** | Copper Alloy (typically Gold or Tin plated) | | **Termination Method** | Solder | | **Orientation** | Right Angle or Straight (depending on sub-series) | ### 2. Key Electronic Characteristics The REB-C4-R is designed to handle high-speed data and maintain signal integrity in compact electronic assemblies. * **Contact Resistance:** Engineered to be extremely low (typically < 30mΩ) to prevent power loss and heat buildup. * **Current Rating:** Usually rated for low-power signal transmission (0.5A to 1.0A per pin). * **Dielectric Withstanding Voltage:** Capable of handling 100V - 250V AC for one minute without breakdown. * **Impedance Matching:** Often used in RF or high-speed data circuits where 50Ω impedance matching is critical for minimizing signal reflection. ### 3. Application Areas These parts are commonly found in the following electronic sectors: 1. **Telecommunications:** Used in GPS modules, Wi-Fi cards, and cellular modems to connect the main PCB to the antenna or daughterboards. 2. **Consumer Electronics:** Found in laptops, tablets, and smartphones where internal space is highly restricted. 3. **Industrial IoT:** Integrated into sensor nodes that require robust, vibration-resistant connections. ### 4. Schematic Representation In a PCB design environment (like Altium, Eagle, or KiCad), the electronic part is represented as follows: ```cpp // Typical Pinout logic for a 4-pin interface Pin 1: Signal_High / VCC Pin 2: Data_Negative (D-) Pin 3: Data_Positive (D+) Pin 4: Ground (GND) / Shield ``` ---
