LAP-401MD ROHM

Single Digit High Brightness LED Numeric Display LAP-401 D / N Series Datasheet LAP-401 D / N series are the numberical display units featuring ROHMs in-house 4-element(AlGaInP) high-brightness LED dies.Their luminous intensity is top class in the industry while degradation is considerably slow, which helps to keep illumination vividness almost unchanged and the image of sets high over a long period of time. Features 1) 10.16mm for letter height, single-line LED numerical displays. 2) About 10 times more luminous intensity than the conventional products by use of 4-element LED dies. (in case of orange color) 3) The same luminous intensity as the conventional products at their 1/10 of current, which contributes lots to energy-saving of sets. 4) Light-leakage from segments probable with the small display packages is very rare. 5) Both anode common type and cathode common type are available in lineup for each color.
