The **W2PA-16A-R/N** is a specialized power distribution component, typically classified as a **Power Entry Module (PEM)** or a **Filtered IEC Inlet**. These parts are essential for managing AC power input while providing electrical safety and noise suppression for sensitive electronic equipment. --- ### 1. Key Technical Specifications Based on the part number nomenclature, the following technical parameters generally apply: | Parameter | Specification | | :--- | :--- | | **Current Rating** | 16 Amperes | | **Voltage Rating** | 250V AC | | **Connector Type** | IEC 60320 C20 (Inlet) | | **Mounting Style** | Panel Mount (Screw or Snap-in) | | **Filter Type** | RFI/EMI Suppression Filter | | **Termination** | Quick-connect terminals or Solder tabs | --- ### 2. Functional Breakdown #### A. Power Input (IEC C20) The "16A" designation indicates a high-capacity current handling. The **C20 inlet** is the standard for 16A-20A applications (common in servers and medical imaging devices), which is larger and handles more heat than the standard 10A C14 inlet found on desktop PCs. #### B. EMI/RFI Filtering The "R/N" often denotes the internal circuitry layout regarding the **Resistor (R)** and **Neutral (N)** line configurations or specific leakage current ratings: * **Noise Suppression:** It contains capacitors (X and Y types) and an inductor (choke) to prevent electromagnetic interference from entering the device or leaking back into the power grid. * **Safety:** It protects the internal electronics from high-frequency transients. #### C. Safety Compliance These parts are usually engineered to meet international safety standards such as: * **UL/CSA:** North American safety standards. * **VDE/ENEC:** European electrical standards. * **RoHS:** Restriction of Hazardous Substances compliant. --- ### 3. Common Applications Due to its high amperage rating (16A), this component is typically found in: * **Data Centers:** High-end servers and Blade chassis. * **Industrial Equipment:** Large-scale CNC machines or control panels. * **Medical Devices:** Diagnostic equipment requiring low leakage current and high power stability. * **Telecommunications:** Network switches and routers. --- ### 4. Schematic Representation Internally, the electronic structure follows a standard Pi-filter or LC-filter circuit: ```text L (Line) ---- [ Inductor ] ---- [ Load ] | | [Cx] [Cy] | | N (Neutral) ---- [ Inductor ] ---- [ Load ] | [GND] ``` ---
