The **W2CE-1C3-R** is an electronic component manufactured by **Kingbright**. It is a specific type of Surface Mount Device (SMD) LED, part of their Subminiature LED series. These are commonly used in high-density applications where space is at a premium. --- ### 1. Technical Specifications The following table outlines the primary electrical and optical characteristics of the W2CE-1C3-R: | Parameter | Specification | | :--- | :--- | | **LED Type** | Subminiature (Dome Lens) | | **Color** | Blue | | **Wavelength** | 470 nm (Dominant) | | **Luminous Intensity** | 400 mcd @ 20mA (Typical) | | **Forward Voltage ($V_F$)** | 3.3V (Typical) | | **Forward Current ($I_F$)** | 30 mA (Max) | | **Viewing Angle** | 20° | | **Package Style** | Gull Wing (Surface Mount) | --- ### 2. Key Features * **Subminiature Design:** The small footprint makes it ideal for backlighting, indicator lights, and wearable electronics. * **Water Clear Lens:** The lens is transparent, allowing for a focused and high-intensity output (20-degree viewing angle). * **Moisture Sensitivity:** Typically rated at MSL 3, requiring proper storage and handling to prevent damage during reflow soldering. * **RoHS Compliant:** The part is lead-free and meets environmental safety standards. --- ### 3. Pinout and Mounting The "Gull Wing" lead configuration is designed for SMD mounting on a PCB. Unlike standard 0603 or 0805 chips, these have physical leads extending from the body. ```markdown [ Lens ] <-- Light output /| |\ / |________| \ / \ [Lead 1] [Lead 2] (Anode) (Cathode) ``` *Note: Always verify the cathode marking (usually a small notch or green line) on the actual physical component before soldering.* --- ### 4. Application Areas 1. **Status Indicators:** Small LEDs for power or data activity in compact routers or modems. 2. **Backlighting:** Used in membrane switches or control panels. 3. **Medical Devices:** Small form factor is useful for handheld diagnostic tools. 4. **Consumer Electronics:** Integration into smart home devices or high-end appliances.
