The **W2SP-113-R** is an electronic component primarily classified as a **Wire-to-Board (W2B) Connector** or a specific type of **Miniature Power Connector**. It is commonly used in industrial and telecommunications applications where space-saving and high-reliability connections are required. --- ### 1. Key Technical Specifications The electrical and mechanical characteristics define its performance within a circuit. | Parameter | Specification (Typical) | | :--- | :--- | | **Connector Type** | SMT (Surface Mount Technology) | | **Pitch** | 2.5mm - 3.0mm (Varies by series specific) | | **Voltage Rating** | 250V AC/DC | | **Current Rating** | 3A - 5A (Depending on wire gauge) | | **Termination Style** | Right Angle (indicated by "-R") | | **Number of Pins** | Defined by the "113" configuration (variant dependent) | --- ### 2. Physical Design & Composition The "R" suffix in the part number typically denotes a **Right Angle** orientation, which is crucial for low-profile PCB designs where vertical space is limited. * **Housing Material:** High-temperature Thermoplastic (UL94V-0 rated), allowing it to withstand reflow soldering temperatures. * **Contacts:** Phosphor Bronze or Copper Alloy, usually plated with Tin or Gold to prevent oxidation and ensure low contact resistance. * **Mounting Type:** SMT with Solder Tabs. These tabs provide mechanical strain relief so that plugging and unplugging the cable doesn't tear the pads off the PCB. --- ### 3. Functional Features * **Polarization:** The housing is keyed to prevent accidental reverse insertion (mating error). * **Friction Lock:** Often includes a small "bump" or latching mechanism to ensure the plug stays secure under vibration. * **Low Profile:** Designed specifically to reduce the "Z-height" on a printed circuit board. --- ### 4. Common Applications Due to its robust but small form factor, the W2SP-113-R is found in: 1. **LED Lighting Strips:** Connecting power drivers to LED boards. 2. **Internal Power Rails:** Connecting batteries to motherboards in portable electronics. 3. **Industrial Sensors:** Providing a detachable interface for field-swappable sensors.
