Cautions (1) The LEDs emit very strong UV radiation. Do not look directly at the LEDs. UV radiation can harm your eyes. To prevent inadequate exposure of UV radiation, wear UV protective glasses. (2) The LEDs are very sensitive to static and surge. Take a full protection against static and surge. (3) The powered LEDs generate heat. Heat dissipation should be considered in the application design to avoid the environmental conditions for operation in excess of the absolute maximum ratings. (4) The leads should be bent at minimum 1.5mm away from the base of header. The LEDs should be soldered at minimum 1.5mm away from the base of header. (5) The LEDs are intended to be used for ordinary electronics equipment. Do not use the LEDs for the applications that may require a higher reliability and security and that the failure or malfunction of the LEDs may threat to life.
