NTE NTE3187

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.
Features:
D Low Power Consumption
D Solid State Blue Light Source
NTE3186 (Blue Diffused)
NTE3187 (Clear Blue)
D Suitable for use in Full Color LED Displays and Indicators in Diagnostic/Analytical Equipment
