(2)High sensitivity
(3)Thin and small package
(4)Pb free
(5)This product itself will remain within RoHS compliant version
 

ITR20403 Descriptions
The ITR20403 consists of an infrared emitting diode(IR1918C)and a silicon phototransistor(PT1918B) encased in a black thermo-plastic housing. The advantage of the device is the small package. Phototransistor receives radiation from the IR LED only, and avoids the noise from ambient light.
