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.
