Pressure is mounting to meet the tightening requirements of the European RoHS directives, which are pushing towards elimination of cadmium altogether. Cadmium is particularly dangerous when airborne in dust form. It can cause lung disease, kidney failure, and even death. To replace the cadmium content while maintaining conductivity and corrosion resistant properties, Corsair … [Read more...]

High Optical Output IR Emitters
Opto Diode announces the third in the family of three super-high-power infrared (IR) emitters. Based on gallium aluminum arsenide (GaAlAs) technology, the new OD-250 features a wide angle, very uniform optical beam with ultra high optical output. Total power output is 250mW (typical) with a minimum output at 160 mW. Peak emission wavelength is 850nm, making this IR emitter … [Read more...]
High Current DC, Single and Three phase AC Filters
LCR Electronics, Inc. has released a new product line of high current DC, single and three phase AC filters. LCR’s high performance, dual stage AC and DC filters were designed with higher inductance common mode coils to reduce excessive common mode emissions generated by high power SCR’s (Silicone-Controlled Rectifiers), and meet the stringent attenuation requirements of … [Read more...]
Arizona Legislators Move to Protect Army Test Facility from Interference
The Arizona state senate passed a bill in 2008 that would protect the U.S. Army's radio and electronic testing site from interference. Senate Bill 1387 requires cities, town, or counties to notify Fort Huachuca commanders when they receive an application to alter property in the military electronics range. Fort Huachuca's unique topography ringed by metal rich mountains … [Read more...]
DO-160 Lightning Simulation Testing added to list of EMI/EMC services
Oct 2007 - When lightning strikes, everyone needs to be confident that important systems will not be damaged. This is especially critical in the Aerospace and Military arenas, where there is a constant need to qualify systems that may be exposed to the indirect induced effects of a lightning strike, and must be tested to demonstrate the ability to function properly under such … [Read more...]
Integrated Design Changes Military Connectors
To meet the prerequisites of commercial aviation with customers like Airbus, Boeing and Dassault, interconnect solutions need to provide full system integration with engine control systems, radar facilities, power distribution networks, in-flight entertainment, wing and engine ice protection mechanisms as well as landing gear and braking control systems. In this context, … [Read more...]
Navy Seeks to Develop Integrated Radar Antennas to Reduce RF Interference
Shipboard radar experts at the U.S. Office of Naval Research (ONR) are asking a select group of 18 U.S. defense contractors to turn their attention to advanced shipboard radar technology that reduces the number of radar antennas on Navy ships by using integrated, multi-function, multi-beam arrays. ONR officials issued a request for information for the Integrated Topside … [Read more...]
