Description
The EL3H7-G ries devices consist of an infrared emitting
diode,optically coupled to a phototransistor detector encapsulated with green compound.
They are packaged in a 4-pin small outline SMD package.
Applications
•DC-DC Converters
• Programmable controllers
• Telecommunication equipments
• Signal transmission between circuits of different potentials and impedances
