Notes:
1. 1.6 mm below seating plane.
2. It is essential that a bypass capacitor 0.01 µF be connected from pin 2 to pin 3 of the receiver.
Receiver Electrical/Optical Characteristics 0°C to 70°C, 4.5 V ≤ VCC ≤ 5.5 V unless otherwise

Notes:
1. Measured at the end of the fiber optic cable with large area detector.
2. Optical flux, P (dBm) = 10 Log P(µW)/1000 µW.
3. Because of the very high sensitivity of the HFBR-25X3, the digital output may switch in response to ambient light levels when a
cable is not occupying the receiver optical port. The designer should take care to filter out signals from this source if they pose a
hazard to the system.
4. Including current in 3.3 k pull-up resistor.
