The **WJPAD2-10B-R** is a specific electronic component typically identified as a **DC Power Jack** or **Power Connector**. These parts are foundational in electronics for delivering external power to a Printed Circuit Board (PCB). Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. Component Overview The WJPAD series generally refers to high-quality DC power connectors used in consumer electronics, industrial equipment, and peripherals. | Feature | Specification Details | | :--- | :--- | | **Part Number** | WJPAD2-10B-R | | **Component Type** | DC Power Jack (Barrel Jack) | | **Mounting Type** | Through-Hole (PTH) / Right Angle | | **Pin Diameter** | Typically 2.0mm or 2.1mm (Standard) | | **Termination** | Solder | | **Orientation** | Horizontal (Side Entry) | --- ### 2. Electrical Characteristics These parts are designed to handle specific voltage and current thresholds to prevent overheating or electrical failure. * **Current Rating:** Usually rated between **2.5A to 5.0A** (depending on the specific revision). * **Voltage Rating:** Typically rated up to **16V DC or 24V DC**. * **Contact Resistance:** $\leq 30m\Omega$ (initial), ensuring minimal power loss at the connection point. * **Insulation Resistance:** $\geq 100M\Omega$ at 500V DC. * **Dielectric Strength:** 500V AC for 1 minute. --- ### 3. Physical & Material Properties The "R" suffix often indicates **RoHS Compliance** or a specific **Reel/Right-angle** configuration. * **Housing Material:** High-temperature thermoplastic (e.g., PBT or PA66), designed to withstand wave soldering temperatures. * **Contact Material:** Copper Alloy with Silver or Tin plating for high conductivity and corrosion resistance. * **Internal Switch:** Many models in this series include a "shunt" or "normality closed" switch that detects when a plug is inserted (useful for switching between battery and wall power). --- ### 4. Common Applications * **Laptops & Notebooks:** As the primary charging port. * **Networking Equipment:** Routers, switches, and modems. * **Medical Devices:** Portable diagnostic tools. * **Consumer Electronics:** Bluetooth speakers, monitors, and DIY microcontroller projects (Arduino/Raspberry Pi power shields). --- ### 5. Mechanical Drawing Concept While specific dimensions should be verified via the manufacturer's datasheet (e.g., Singatron or similar vendors), the footprint usually follows this logic: ```text [ Front View ] [ Side View ] ________________ _______ | ( ) | | |--[Pin 1: Positive] |________________| |_______|--[Pin 2: Ground] |--[Pin 3: Switch] ``` ---
