Description
These devices are developed for applications with 5 V
sources.
The TLR.445. series contains an integrated resistor for
current limiting in series with the LED chip. This allows
the lamp to be driven from a 5 V source without an
external current limiter.
Available colors are red, high efficiency red, yellow and
green. The luminous intensity of such an LED is
measured at constant voltage of 5 V.
These tinted diffused lamps provide a wide off-axis
viewing angle.
These LEDs are intended for space critical
applications such as portable sets, switches and oth-
ers which are driven from a 5 V source.
