The **WEPA-11MD2-R** is a specific electronic component, typically categorized as a **Surface Mount (SMT) Low Profile Wire-to-Board Header**. It is widely used in compact consumer electronics, automotive interior lighting, and industrial control panels where space is a critical constraint. Below is a detailed breakdown of its technical specifications and features. --- ### 1. General Specifications The WEPA series is known for its miniature footprint and reliable connectivity. | Feature | Specification | | :--- | :--- | | **Component Type** | Male Header (Wire-to-Board) | | **Mounting Type** | Surface Mount Technology (SMT) | | **Pitch (Spacing)** | 1.0mm or 1.25mm (Series dependent) | | **Number of Pins** | 11 Pins | | **Orientation** | Right Angle (Horizontal) | | **Plating** | Tin or Gold Flash over Nickel | ### 2. Key Electronic & Material Characteristics This part is engineered for low-power signal transmission and high-density PCB layouts. * **Current Rating:** Typically supports up to **1.0A AC/DC** per pin. * **Voltage Rating:** Usually rated for **50V to 100V AC/DC**. * **Contact Resistance:** Low initial resistance (approx. 20mΩ max) to ensure signal integrity. * **Insulation Material:** High-temperature thermoplastic (LCP or Nylon 9T), capable of withstanding **Reflow Soldering** temperatures (up to 260°C). * **Reinforcement:** Often includes "Solder Tabs" or metallic "bosses" on the sides to provide mechanical strain relief to the SMT joints. ### 3. Application Areas Due to its low profile and right-angle design, it is found in: 1. **Display Modules:** Connecting LCD/LED backlights to the main controller. 2. **Handheld Devices:** Internal battery or speaker connections. 3. **Sensors:** Interfacing small sensor boards with motherboards. 4. **Automotive:** Infotainment systems and dashboard controls. ### 4. Part Number Breakdown (Typical) While naming conventions vary by manufacturer (often associated with brands like JST, Molex, or regional equivalents), the suffix usually denotes: * **11:** The number of circuits/positions. * **MD:** Mounting type (e.g., SMT Right Angle). * **R:** Packaging type (usually **Tape & Reel** for automated pick-and-place machines). ---
