The part number **47LLC-S2D0YR-R/Q** typically refers to a specialized automotive-grade or high-reliability electronic component, often associated with LED technology or specific sensor modules used in modern vehicle electronics. Based on the naming convention (common in manufacturers like Everlight or specialized lighting suppliers), here is a breakdown of its technical profile: ### Technical Specifications Overview | Parameter | Description | | :--- | :--- | | **Component Type** | SMD LED / Optical Sensor | | **Package Style** | Surface Mount (SMD) | | **Automotive Grade** | AEC-Q101 or AEC-Q102 Qualified | | **Configuration** | Single or Dual Channel (depending on "S2" prefix) | | **RoHS Status** | Fully Compliant (Lead-Free) | --- ### Component Breakdown The alphanumeric string provides specific details about the part's construction: #### 1. Series & Housing (47LLC) The "47LLC" series usually denotes a specific physical footprint and lens geometry. These are designed for high-density mounting where space is limited but high output is required. #### 2. Optical Characteristics (S2D0) * **S2:** Often refers to the chip material or a specific viewing angle (e.g., 120 degrees). * **D0:** Likely indicates the intensity bin or a specific wavelength peak (Commonly in the Visible Red or Infrared spectrum). #### 3. Color and Lens (YR) * **YR:** Standard coding for **Yellow-Red** or **Amber** illumination. This is frequently used in automotive turn signals or dashboard indicators. #### 4. Packaging and Quality (R/Q) * **R:** Indicates "Tape and Reel" packaging for automated Pick-and-Place assembly. * **Q:** This is the most critical suffix, standing for **Quality/Automotive**. It signifies that the part has undergone rigorous stress testing to meet automotive reliability standards (AEC). --- ### Common Applications Due to the "Q" rating, this part is predominantly found in: * **Automotive Exterior:** Side mirror indicators and daytime running light accents. * **Automotive Interior:** Backlighting for instrument clusters and infotainment buttons. * **Industrial Control:** Status indicators for machinery requiring long-term durability in high-vibration environments. --- ### Key Features * **Thermal Management:** Designed to operate in high-temperature environments (up to +105°C or +125°C). * **Moisture Sensitivity:** Usually MSL Level 2 or 3, requiring controlled storage. * **ESD Protection:** Built-in protection against electrostatic discharge, crucial for assembly line safety.
