Description
The EL3H7-G series 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
