LED Lighting WL-SWTP White, Warm 2700K 3V 20mA 120° 1206 (3216 Metric) The 158301227 is a surface-mount white LED manufactured by Würth Elektronik, belonging to the WL-SWTP series of top-view PLCC-packaged light-emitting diodes designed for general illumination, backlighting, and signal indication applications in compact electronics. It is built on a gallium nitride semiconductor chip, the standard chip technology used in high-efficiency white LED production, which achieves white light emission by combining a blue GaN die with a phosphor conversion layer that down-converts a portion of the blue photons into broader-spectrum yellow light, with the combined blue and yellow output perceived by the human eye as white light. This particular variant is characterized by a warm white Sunrise color temperature, placing it in the lowest color temperature tier of the WL-SWTP family. Warm white light at this color temperature produces a yellowish, incandescent-like appearance that is widely preferred in residential, hospitality, and ambient lighting applications where a soft, comfortable visual environment is desired. This makes the device a natural fit for LED-based replacements for incandescent and halogen light sources in T5 and T8 fluorescent tube form factor products, as well as indoor display backlights, decorative architectural lighting, and other applications where a warm light quality is specified or preferred by end users. The WL-SWTP series features fast switching, no infrared radiation, high color rendering index, slim and miniature size, low power consumption, suitability for all SMT assembly methods, a top-view emission direction, and a wide viewing angle. The high color rendering index characteristic of this device means that objects illuminated by it appear with colors close to how they would look under natural daylight illumination, which is an important quality metric in retail, museum, medical examination, and other environments where accurate color representation enhances user experience or functional accuracy. Texas Instruments The PLCC package style used in this device is a molded plastic leaded chip carrier format that provides a well-defined, mechanically stable footprint for surface-mount assembly, with the optical emitting surface oriented perpendicular to the PCB plane in the top-view configuration. This top-view orientation makes the device suitable for direct illumination of surfaces positioned above the PCB, such as diffusers, light guides, or display panels mounted parallel to the LED board. The compact 3014 package footprint allows high-density LED arrays to be assembled on narrow PCB strips or modules, which is typical in LED tube light and edge-lit backlight designs. The device is supplied on tape-and-reel packaging suitable for automated high-speed pick-and-place assembly at production volumes.
