Page 14 of 15 Cautions Sulphur Reverse Bias ESD Avoid storing or operation the LEDs in a sulphur containing environment. Some materials, such as seals, printing ink, enclosure and adhesives, may contain sulphur. Avoiding the exposure in acid or halogen environment. These LEDs are not designed to operate in reverse bias. Precautions are required to prevent reverse bias in applications and during handling. These LEDs are ESD sensitive. Safe ESD handling precautions are required.
