0.4W High Power SMD LEDs

The Seoul Semiconductor STW8Q2PA and SFT825N are 0.4W high power SMD LEDs featuring ultra slim size and high reliability. Seoul Semiconductor STW8Q2PA LEDs are white LEDs suitable for all SMT assembly and soldering methods. STW8Q2PA 0.4W SMD LEDs offer high color rendering index (CRI) and are ideal for electric signs and signals, interior automotive, office automation, electrical appliances, and industrial equipment. Both the STW8Q2PA and SFT825N feature a viewing angle of 120º. Seoul Semiconductor SFT825N 0.4W full color LEDs perform with high reliability in a wide temperature range of -40ºC to 100ºC. SFT825N full color LEDs are optimized for use in indoor and outdoor displays, automotive applications, LCD backlights, and signage and channel letter applications.
