Description

These devices are developed for the automotive
industry with special requirements as for EMC (electro
magnetic compatibility) in motor vehicles with 12 V
supply voltage.
They are resistant against transient conduction (high
voltage spikes) and interferences by conduction and
coupling.
The TLR.442. 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.
Available colors are red, soft orange, yellow and
green. These tinted diffused lamps provide a wide
off-axis 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.
