Würth Elektronik’s new WL-SFTW and WL-SFTD series of RGB LEDs are targeted at accent and decorative lighting, optical displays as well as industrial applications. Thanks to their PLCC contacting design, the two series of individually controllable LEDs are well suited for SMT assembly and reflow soldering.
The WL-SFTW series offers three standard packaging designs: 3528 with four pins, and 3528 and 5050, each with six pins. The WL-SFTD series, in the 3535 package, may be of particular relevance to lighting designers as it is characterised by its IPX6 protection class.
RGB LEDs can be used to create any colour by additive colour mixing, which is appealing for a variety of decorative applications. With the WL-SFTW series LEDs, Würth offers compact components with high light intensity. The 5050 package, in particular, is ideal for applications in areas with bright ambient light.
The IPX6 protection class of the WL-SFTD series makes it suitable for outdoor applications and insensitivity to water. The encapsulation resin of the RGB LED with diffuse lens also contains UV inhibitors to minimise the effects of long-term exposure to direct sunlight. This supports stable light yield throughout the service life of the LED. A wide beam angle and high intensities make these LEDs ideal for outdoor and indoor full-colour displays.
