Description
These devices are developed for the automotive industry
and other industries which use 12 V sources.
The TLR.440. series contains an integrated resistor for
current limiting in series with the LED chip. This allows
the lamp to be driven from a 12 V source without an exter-
nal current limiter.
Available colors are red, soft orange, yellow, green and
pure green. The luminous intensity of such an LED is
measured at constant voltage of 12 V.
These tinted diffused lamps provide a wide off-axis view-
ing angle.
These LEDs are intended for space critical applications
such as automobile instrument panels, switches and oth-
ers which are driven from a 12 V source.
