SME2470-021

Overview

SME2470 Series Infrared Emitting Diode, Surface-mount Package, Glass Lens.
The SME2470 series surface mount infrared components are small ceramic packages (0.15 in x 0.10 in x 0.083 in /3.81 mm x 2.54 mm x 2.1 mm) with glass lenses. The lens minimizes cross talk and often eliminates the need for apertures in non-critical applications. The low profile components may be mounted on the printed circuit board, lens up or inverted, allowing flexibility in layouts for multiple channel and custom arrays. When mounted lens down over a hole in the PC board, the lens is hidden, lowering overall package height.

The SME2470 is a high intensity aluminum gallium arsenide infrared emitting diode (IRED) which can be used with either the SMD2440 phototransistor or the SMD2420 photodiode. It supplies optimum optical characteristics and efficient optical coupling. The small size and high power dissipation properties of the IRED promote PC board miniaturization and high density placement.

These components are available in bulk, or on tape and reel for use with automatic placement equipment.
