NTE3186 & NTE3187 Discrete Blue LED Indicators Description: The NTE3186 and NTE3187 are blue source color light emitting diodes made with GaN on SIC. It is recommended that a wrist strap or anit–electrostatic glove be used when handling these devices as static electricity and surge will damage these devices. All devices, equipment, and machinery must be electrically grounded.
