Instructions for EL817(C)

1. Mounting and Handling:

   • Handle the EL817(C) with care to avoid physical damage.
   • Ensure proper alignment during mounting to prevent short circuits or misconnections.

2. Electrical Connections:

   • Connect the LED side (input) in series with a current-limiting resistor to ensure the forward current (IF) does not exceed the maximum rating.
   • The phototransistor side (output) should be connected in a circuit that can handle the output current (IC).

3. Power Supply Considerations:

   • Ensure the power supply voltage is within the operating range to avoid damaging the device.
   • Use appropriate decoupling capacitors near the power supply lines to minimize noise.

4. Heat Management:

   • Keep the operating temperature within the specified range (-40掳C to 85掳C).
   • If necessary, use heat sinks to dissipate excess heat, especially when operating at higher currents.

5. Testing and Troubleshooting:

   • Test the device under controlled conditions to verify its performance.
   • Check for proper connections and correct polarity if the device does not operate as expected.

6. Storage:

   • Store the EL817(C) in a dry, cool place away from direct sunlight and corrosive materials.
