T-1 3/4

For right-angle and vertical viewing, the QT Optoelectronics LED circuit board indicators come in T-3/4, T-1 and T-1 3/4 lamp sizes, and in single, dual and multiple packages. The indicators are available in AIGaAs red, high-efficiency red, bright red, green, yellow, and bi-color at standard drive currents, as well as at 2 mA drive current. To reduce component cost and save space, 5 V and 12 V types are available with integrated resistors. The LEDs of T-3/4, T-1 and T-1 3/4 are packaged in a black plastic housing for optical contrast, and the housing meets UL94V-0 flammability specifications.
