Infrared Light Emitting Diode in SMD Plastic Package OP270 Series 890nm Wavelength Narrow Beam Angle High Power 1.9mm Water Clear Plastic Package Four Lead Configurations Description: The OP270 series are GaAlAs infrared LEDs mounted in a clear plastic SMT packages. The devices incorporate an integral molded lens which enables a narrow beam angle and provides an even emission pattern. This series is available with four lead configurations and is compatible with most automated mounting equipment. The OP270 Series LEDs are mechanically and spectrally matched to the OP570 series phototransistors.

E is a measurement of the apertured radiant incidence upon a sensing area 0.081 (2.06mm) in diameter, perpendicular to and cen- e(APT) tered on the mechanical axis of the lens, and 0.590 (14.99mm) from the measurement surface. E is not necessarily uniform within e(APT) the measured area.
