The **WRPPB-JM5AN-R** is a specific surface-mount (SMT) connector component, primarily associated with high-density board-to-board or board-to-FPC (Flexible Printed Circuit) applications. It is part of the **WP** series (or similar micro-pitch families) often manufactured by companies like **JAE (Japan Aviation Electronics)** or specialized connector firms. --- ### 1. Component Overview This part is a **plug/receptacle connector** designed for miniature electronic devices where space is at a premium. | Feature | Specification | | :--- | :--- | | **Part Number** | WRPPB-JM5AN-R | | **Type** | Board-to-Board / Board-to-FPC Connector | | **Contact Pitch** | Usually 0.4mm or 0.5mm (High Density) | | **Mounting Type** | Surface Mount Technology (SMT) | | **Orientation** | Straight / Vertical | | **Packaging** | Tape and Reel (indicated by the "-R") | --- ### 2. Detailed Technical Breakdown #### A. Mechanical Construction * **Housing:** High-temperature thermoplastic (LCP - Liquid Crystal Polymer) capable of withstanding lead-free reflow soldering. * **Contacts:** Copper alloy with gold plating to ensure low contact resistance and prevent oxidation over time. * **Shielding:** Many variants in this series include a "hold-down" or metal armor to protect the plastic housing from damage during accidental drops or rough mating. #### B. Electrical Characteristics * **Current Rating:** Typically 0.3A to 0.5A per contact. * **Voltage Rating:** Generally 50V AC/DC. * **Dielectric Withstanding Voltage:** 250V AC for 1 minute. * **Insulation Resistance:** 100MΩ minimum. #### C. The "R" Suffix The **-R** at the end of the part number is critical for manufacturing. It stands for **Reel**. This means the parts are delivered in embossed carrier tape compatible with automated "Pick and Place" machines used in mass production assembly lines. --- ### 3. Common Applications Due to its small footprint and reliability, this part is commonly found in: * **Smartphones:** Connecting the main PCB to the display or camera module. * **Wearables:** Smartwatches and fitness trackers. * **Medical Devices:** Compact diagnostic handhelds. * **IoT Modules:** Small-form-factor sensor boards. --- ### 4.
