Questions


Question by Martin Wood
11 November 2013

QI would like to create a flashing 1.8mm LED tail lamp on a model railway truck. I propose to power this with the coin cell type battery, (2 x 1.5v) will this unit work? I am also wishing to create a lvel crossing warning light with 2 alternate flashing LED's, could I also use this component?
AHi Martin, thanks for your question. This component can be used to make the LEDs flash. We also offer flashing LEDs which have the IC built in to make them flash independently: A 3mm version and 5mm version.

THESE DEDICATED IC'S ARE IDEAL FOR SMALL 3VOLT BATTERY DRIVEN LED FLASH CIRCUITS, NO CURRENT LIMIT RESISTORS ARE NEEDED HENCE VERY LOW COMPONENT COUNT. -THE ONLY PROBLEM WE FOUND IS THAT IF YOU REQUIRE ADDITIONAL STATIC LEDS TO BE POWERED FROM THE SAME SUPPLY THE CURRENT DRAIN TO TOO GREAT MAKING THE STATIC LEDS DIM
