Based on the technical specifications for the **WJT-323-R**, this component is a **Vertical 3-pin AC Power Socket** (often referred to as an IEC C14 inlet or a standard AC power interface) commonly used in power supplies, industrial equipment, and household appliances. ### 1. Key Technical Specifications The electrical integrity of the WJT-323-R is defined by its ability to handle high voltage and current safely. | Parameter | Specification | | :--- | :--- | | **Rated Load** | 10A / 250V AC | | **Contact Resistance** | $\le 30m\Omega$ | | **Insulation Resistance** | $\ge 100M\Omega$ (at 500V DC) | | **Withstand Voltage** | 2000V AC / 1 minute | | **Operating Temperature** | $-25^\circ C$ to $+85^\circ C$ | | **Service Life** | $\ge 10,000$ Cycles | --- ### 2. Physical & Electronic Construction The "electronic" functionality of this part is passive, focusing on conductivity and insulation. * **Housing Material:** Typically made of **PBT (Polybutylene Terephthalate)** or Nylon 66, which are flame-retardant (UL94V-0 rated) to prevent melting or ignition during electrical shorts. * **Conductive Pins (Terminals):** Constructed from **Brass (CuZn)**, usually plated with **Nickel or Tin** to prevent oxidation and ensure low contact resistance over time. * **Pin Configuration:** It features 3 terminals: 1. **Line (L):** Hot wire connection. 2. **Neutral (N):** Return path. 3. **Earth/Ground (E):** Safety ground to prevent electric shock. * **Termination Type:** The "R" in the suffix often denotes the specific terminal orientation or mounting style (Right-angle or specific solder tab layout). --- ### 3. Safety Compliance Electronic components dealing with AC mains must adhere to international safety standards to be used in consumer electronics. The WJT-323-R typically carries certifications from: * **UL/cUL:** North American safety standards. * **VDE:** European electrical standards. * **RoHS:** Restriction of Hazardous Substances (Lead-free). ### 4.
