## Technical Overview: C4SMT-RJS-CS0V0BB2 The **C4SMT-RJS-CS0V0BB2** is a high-performance, **Red Oval Through-Hole LED** manufactured by **Cree LED (formerly Cree Inc.)**. It is specifically designed for outdoor video screens and signage due to its high brightness and wide viewing angle. --- ### Key Specifications | Parameter | Value | | :--- | :--- | | **Color** | Red (621nm Typ.) | | **Luminous Intensity** | 770 - 2130 mcd | | **Viewing Angle** | 70° (Horizontal) / 35° (Vertical) | | **Package Type** | 4mm Oval Through-Hole | | **Forward Current ($I_F$)** | 50 mA | | **Forward Voltage ($V_F$)** | 2.1V (Typical) | | **Lens Appearance** | Tinted / Diffused | --- ### Component Features 1. **Optical Design**: The "Oval" shape is intentional. It provides a wide horizontal viewing angle ($70^\circ$) and a narrower vertical angle ($35^\circ$), which is optimal for roadside displays and billboards where the audience is usually at eye level but spread across a wide area. 2. **UV Resistance**: The epoxy resin contains UV inhibitors, making it suitable for direct sunlight exposure without significant degradation or yellowing over time. 3. **Material**: This LED uses **AlGaInP** (Aluminium Gallium Indium Phosphide) technology, which is the standard for high-efficiency red, orange, and yellow LEDs. 4. **Environmental Stability**: It is built to withstand outdoor conditions, featuring high moisture resistance. --- ### Pinout and Mechanical Data The device follows a standard 2-pin through-hole configuration: * **Anode (+)**: Longer lead. * **Cathode (-)**: Shorter lead, usually marked by a flat side on the LED base. ```text _____ / \ | | <-- 4mm Oval Lens |_______| | | | | | | <-- Leads (Anode/Cathode) + - ``` --- ### Common Applications * **Electronic Passenger Information Signs**: Bus stops and train stations. * **Full-Color Video Screens**: Large-scale outdoor billboards. * **Variable Message Signs (VMS)**: Highway traffic management displays. * **Digital Signage**: Commercial advertising boards. ---
