TT electronics Optek Technology has developed a miniature half-watt surface-mount LED package. The OVS5MxBCR4 measures 3.5 × 3.5 × 1.2 mm and is available with white, warm-white, blue, green, red, amber and yellow LEDs. It features a 120° viewing angle and a water-clear lens. Power dissipation at 150 mA is 0.48 W for the white, warm- white and blue, 0.51 W for the green, and 0.33 W for the red, amber and yellow. Typical luminous intensity is 4000, 4500 and 5000 mcd for the red, amber and yellow LEDs, respectively. Luminous flux for the white, warm-white, blue and green models is 25, 25, 6 and 25 lm, respectively. Operating temperature ranges from –40 to 100 °C.
