### Technical Overview of CP41B-ADS-CM0P0454 The **CP41B-ADS-CM0P0454** is a high-brightness **Amber (Yellow/Orange) LED** manufactured by **Cree LED (Wolfspeed)**. It belongs to the P4 family of "Super Flux" or "Piranha" LEDs, known for their distinctive square package and four-lead design which provides excellent stability and heat dissipation. --- ### Key Specifications | Parameter | Specification | | :--- | :--- | | **Emitted Color** | Amber (Yellow) | | **Wavelength** | 584nm - 596nm (Dominant) | | **Luminous Flux** | 4.4 lm - 11.0 lm | | **Viewing Angle** | 45 Degrees | | **Package Type** | P4 (Square 7.6mm x 7.6mm) | | **Forward Current** | 70mA (Test Current) | | **Forward Voltage** | 2.1V - 2.6V (Typical) | | **Lens Appearance** | Water Clear | --- ### Core Electronic Characteristics #### 1. Thermal Management Unlike standard 5mm round LEDs, the CP41B uses a **4-lead frame**. This design allows heat to be transferred more efficiently from the LED die to the PCB. This makes it suitable for high-duty cycle applications where thermal stability is critical. #### 2. Optical Performance * **Radiation Pattern:** The 45-degree viewing angle provides a directional but slightly diffused beam, making it ideal for signaling rather than wide-area illumination. * **Intensity:** With a luminous flux reaching up to 11 lumens at 70mA, it is significantly brighter than standard indicator LEDs. #### 3. Material Composition * **Chip Material:** AlInGaP (Aluminum Indium Gallium Phosphide). This technology is standard for high-efficiency red, orange, and amber LEDs. --- ### Typical Applications * **Automotive Lighting:** Exterior turn signals, stop lamps, and side markers. * **Electronic Signs:** Variable Message Signs (VMS) and traffic signals. * **Amusement Lighting:** Decorative lighting for parks and gaming machines. * **Industrial:** Status indicators that require high visibility in bright environments. --- ### Dimensions and Footprint The package is a **7.6mm square**. The four pins are arranged to provide a robust mechanical fix to the circuit board, reducing the risk of failure due to vibration or shock.
