LED Current Limiting Resistor
A resistor to limit current to the LED is required. The recommended value is 121Ω (±1%) for 254 LPI and 255Ω (±1%)
for 318 LPI. The resistor should be placed in series between the 2.8 V supply and pin 1 of the device (V
result in an LED current of approximately 6mA.
Moisture Sensitive Level
The AEDR-8400 is specified to moisture sensitive level (MSL) 3.
