FEATURES
• Integral current limiting resistor (No external resistor required)
• Operates with 5 volt & 12 volt supplies
• Wide viewing angle
• Solid state reliability
DESCRIPTION
These T-1 3/4 LED lamps contain an integral
resistor. Operation at 5 volts (MR3X50) or 12 volts
(MR3X51) is possible without the use of an exter-
nal current limiting resistor. The epoxy lens is tint-
ed and diffused to provide color identification and
a wide viewing angle.
