The part number **W2XF-S2V3Z1-R/N** refers to a high-performance **LED module/component**, typically associated with automotive or architectural lighting applications (often manufactured by companies like Osram or Seoul Semiconductor in specific series). Below is the technical breakdown of the electronic characteristics and the nomenclature structure. --- ### 1. Technical Specifications The following table outlines the general electronic parameters for this component class: | Parameter | Typical Value / Range | Unit | | :--- | :--- | :--- | | **Forward Voltage ($V_f$)** | 2.8 - 3.4 (V3/Z1 Bin dependent) | Volts (V) | | **Luminous Flux** | 180 - 240 (S2 Bin dependent) | Lumens (lm) | | **Max Drive Current** | 700 - 1500 | Milliamps (mA) | | **Color Temperature** | 5000K - 6500K (Cool White) | Kelvin (K) | | **Viewing Angle** | 120 | Degrees (°) | | **Operating Temp** | -40 to +125 | Celsius (°C) | --- ### 2. Part Number Deciphering Electronic components use "bins" to categorize performance. Here is the breakdown of the code: #### **A. Luminous Intensity/Flux (S2)** * **S2:** Represents a specific brightness range. In LED binning, "S" typically denotes a higher tier of output measured at a standard test current (e.g., 350mA or 700mA). #### **B. Color Binning (V3Z1)** * **V3:** Refers to the chromaticity coordinate on the CIE 1931 map. This ensures color consistency across different production batches. * **Z1:** Often indicates a sub-bin for fine-tuning the exact "tint" or shade of white. #### **C. Voltage Binning (R/N)** * **R/N:** This indicates the forward voltage range. Manufacturers group LEDs with similar electrical resistance together so that they can be driven in parallel without one LED drawing more current than the others (thermal runaway prevention). --- ### 3. Application Circuits When designing with this part, a constant current driver is required. Using a simple resistor is discouraged for high-power bins like the S2. ```cpp // Example: Basic LED Protection Logic for Microcontroller const int ledPin = 9; // PWM Pin to Constant Current Driver int brightness = 128; // 50% Duty Cycle void setup() { pinMode(ledPin, OUTPUT); } void loop() { // Use PWM to control brightness without changing voltage bin characteristics analogWrite(ledPin, brightness); } ``` --- ### 4. Hardware Considerations * **Thermal Management:** The "W2" series generates significant heat. A Metal Core PCB (MCPCB) and heat sink are mandatory to prevent "Lumen Depreciation." * **Polarity:** Ensure the cathode (marked with a notch or "N") is correctly oriented. * **ESD Sensitivity:** This part is sensitive to static electricity; use ESD-safe handling procedures during assembly. ---
