Miniature Low Cost LDR

Photoconductive cadmium sulphide light dependent resistor (LDR) in a miniature epoxy sealed open frame package (4mm dia.). Cell resistance reduces as light falling on the device increases. Typical applications include light control, cameras, toys etc.

Peak spectral response: 540nm.
Light resistance: 50-100Kohm
Dark resistance: 20Mohm min.
Max. voltage: 100V
Power max: 90mW
Working temp. range: -20 to +60°

This device contains cadmium sulphide, which is restricted by the RoHS directive.
