® Kingbright 3.5x2.8mm SURFACE MOUNT LED LAMPS KA-3528 KAA-3528 Description Features lSINGLE COLOR AND BI-COLOR SMT LED. lBOTH CHIPS CAN BE CONTROLLED SEPARATELY. lSUITABLE FOR ALL SMT ASSEMBLY AND SOLDER PROCESS. lAVAILABLE ON TAPE AND REEL. lIDEAL FOR BACKLIGHTING. The Super Bright Green source color devices are made with Gallium Phosphide Green Light Emitting Diode. The High Efficiency Red source color devices are made with Gallium Arsenide Phosphide on Gallium Phosphide Orange Light Emitting Diode. The Yellow source color devices are made with Gallium Arsenide Phosphide on Gallium Phosphide Yellow Light Emitting Diode. The Super Bright Red source color devices are made with Gallium Aluminum Arsenide Red Light Emitting Diode. The Super Bright Yellow source color devices are made with DH InGaAlP on GaAs substrate Light Emitting Diode. The Blue source color devices are made with GaN on SiC Light Emitting Diode. Static electricity and surge damage the LEDS. It is recommended to use a wrist band or anti-electrostatic or anti-electrostatic glove when handing the LEDs. All devices, equipment and machinery must be electrically grounded. Package Dimensions Notes: 1. All dimensions are in millimeters (inches). 2. Tolerance is ±0.25(0.01") unless otherwise noted. 3. Lead spacing is measured where the lead emerge package. 4. Specifications are subjected to change without notice. 1-KA-3528-1 Selection Guide Part No. Dice Lens Type Iv (mcd) @ 20 mA Viewing Angle Min.
