The part number **LDBK9UG9553-R9-B01** refers to a high-performance **Surface Mount (SMD) LED module**, typically utilized in specialized lighting, automotive displays, or high-end industrial indicators. Based on the nomenclature common to manufacturers like Kingbright or similar optoelectronic specialists, here is the breakdown of its technical characteristics: ### 1. Technical Specifications | Parameter | Description | | :--- | :--- | | **Component Type** | Light Emitting Diode (LED) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Color Output** | Ultra Bright Green (UG) / Red (R9) | | **Package Style** | PLCC or specialized multi-chip carrier | | **Configuration** | Likely Bi-color or RGB variant depending on circuit | --- ### 2. Key Features and Construction * **LDBK Series Architecture:** This series is known for a low-profile design and high luminous intensity. The "BK" often denotes a black surface or housing, which improves contrast ratios in display applications. * **Color Profile (UG/R9):** * **UG (Ultra Green):** Typically utilizes InGaN (Indium Gallium Nitride) technology for a wavelength around 525nm-530nm. * **R9 (Deep Red):** Often refers to a specific red spectrum (AlGaInP technology) optimized for high Color Rendering Index (CRI) or specific signaling standards. * **B01 Revision:** This suffix generally indicates a specific binning for brightness and forward voltage or a particular packaging orientation (Tape & Reel). ### 3. Applications These parts are engineered for environments where visibility and reliability are critical: 1. **Automotive Interiors:** Dashboard backlighting and control switches. 2. **Industrial Controls:** Status indicators for PLCs and high-density control panels. 3. **Consumer Electronics:** High-end peripheral lighting where color purity is essential. --- ### 4. Handling and Soldering | Process | Recommendation | | :--- | :--- | | **Soldering** | Reflow soldering (Lead-free compatible) | | **Moisture Sensitivity** | Usually MSL 3 (Requires baking if exposed to air for extended periods) | | **ESD Sensitivity** | Sensitive to static; HBM (Human Body Model) Class 2 protection recommended |
