26 Jan 16. Vishay Intertechnology, Inc. (NYSE: VSH) introduced a new metal-core-based cool white LED power module featuring 12 high-brightness LEDs with high luminous flux of 4000 lm each at 1 A. To simplify designs and manufacturing processes, the Vishay Semiconductors VLSL12A03-3Q3T-50A can be combined with off-the-shelf LEDiL quadruple lenses, while its integrated small thermal sensor (NTCS0603E347JHT) and fourfold plug-in connector (87438-0443) eliminate the need for additional soldering.
Optimized for illumination in internal building lighting, street lighting, tunnel lights, industrial lighting, and general lighting applications, the 12 LM80-certified LEDs of the VLSL12A03-3Q3T-50A are serially connected on an aluminum metal-core, single-side PCB measuring 161 mm by 50 mm by 2 mm and featuring a shiny white surface. To allow for a variety of emission patterns, this layout is compatible with LEDiL 2×2 STRADA and High Bay quadruple lenses.
Based on InGaN (indium gallium nitride) technology, the VLSL12A03-3Q3T-50A provides a maximum current of 1500 mA, color temperature from 4700 K to 5500 K, power dissipation of 55 W, and forward voltage from 33.6 V to 40.8 V at 1 A. The LED module offers an angle of half intensity of ± 60° and luminous flux binning. RoHS-compliant, halogen-free, and Vishay Green, the device provides ESD withstand voltage up to 2 kV in accordance with JESD22-A114-B.
Samples and production quantities of the VLSL12A03-3Q3T-50A are available now. Design engineers may request samples by sending an email to . Lead time for production quantities is six to eight weeks.
26 Jan 16. USAF’s MET at Udeid Air Base in Qatar begins operations. The US Air Force’s (USAF) first fully funded modernisation enterprise terminal (MET) installed at Al Udeid Air Base, Qatar, has commenced operations. Part of the US Department of Defense’s (DoD) MET programme, the terminal valued at $15m will provide secure communication capabilities including voice, video and data services, to the US Central Command. The system uses the latest technology and features anti-jamming software. 379th Expeditionary Communications Squadron plans and programmes manager Vernon Jones said: “It provides tremendous capability and reliability to the warfighter.
“It ensures the CENTCOM commander has the communication capability to get his guidance to his subordinate commanders to execute the mission.
“It also provides the assurance to the warfighter that when an extraction team or a rescue helicopter is needed, it will be there.”
The MET programme is aimed at enabling US military forces the advantage of increased data capabilities of its constellation of Ka-band wideband global communication satellites.
DoD’s MET programme 379th ECS commander lieutenant colonel Carlos Alford: “The programme’s goal is to install new terminals around the world.
“The MET will simultaneously handle both X and Ka-band signals which use WGCS.
“The previous Defense Satellite Communications System could only handle X-band and one WGCS satellite is equal to about 10 DSCS satellites in terms of bandwidth it provides.”
Work to set up the terminal began towards the end of 2012.
A second MET is expected to be installed at Al Udeid AB in 2018 to further increase CENTCOM’s communication capabilities. (Source: naval-technology.com)
