Description

These devices are developed for the automotive
industry and other industries which use 12 V sources.

The TLRP4900 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 external current limiter.
The luminous intensity of such an LED is measured
at constant voltage of 12 V.
These untinted non diffused lamps provide a wide off­axis viewing angle.
These LEDs are intended for space critical
applications such as automobile instrument panels,
switches and others which are driven from a 12 V
source.
