The Rohm Semiconductor 331066 is an infrared (IR) side-view LED designed for optoelectronics applications. It has a forward voltage of 1.2V and a viewing angle of 24 degrees. The wavelength of the LED is 950nm, and it has a radiant intensity of 0.9mW/sr at 20mA. The LED is mounted on an SMD (SMT) package and comes in a reel - TR packaging. The 331066 is obsolete (EOL) and has a temperature range of -30°C to 85°C (TA). The maximum continuous forward current of the LED is 40mA, and its popularity is medium. However, there is a 54% fake threat in the open market, and the supply and demand status is limited.
