Agilent Rolls Out HSDL-4261 High-Speed, 870 Nanometer Infrared Emitter

8/26/2004 - Agilent Technologies Inc. (NYSE: A) introduced a new high-speed LED infrared (IR) emitter. The new product, from Agilent's Semiconductor Products Group, uses the company's high-power aluminum gallium arsenide (AlGaAs) LED technology, which has been optimized for high radiant intensity, speed and low forward voltage.

The Agilent HSDL-4261 IR emitter provides manufacturers with a low-cost illumination source suitable for a broad range of applications, from communication devices and IR LANs to consumer products such as optical mice, IR headphones, microphones and keyboards.

The HSDL-4261 emitter features 15 ns rise time and 45 ns fall time (10 percent to 90 percent), with intensities of up to 180 mW/sr (typical) at ILED=100 mA at a 26-degree viewing angle. It operates at the 870 nm optical wavelength and is supplied in an industry-standard 5 mm (T-1 3/4) form-factor package.

The Agilent IR emitter is built with iron lead frames that dissipate power efficiently over a wide range of currents. The forward voltage is a low 1.40 volts at 20 mA, which, in some applications, allows two or more of the emitters to be connected in series without exceeding the supply-voltage capability.

U.S. Pricing and Availability
The Agilent HSDL-4261 is priced at $0.12 each in moderate volumes and is available now through Agilent's direct sales channel and worldwide distribution partners. Further information about Agilent's infrared products is available at
