Capacitive load switching sources in military systems: How to extend relay switching life and reliability
With high-performance electromechanical relays continuing to play an important part in military and aerospace applications, it is important for engineers to capture all the electrical requirements. A critical area is extending relay switching life under capacitive transient high inrush current conditions by complying with manufacturers' relay product performance specifications. Capacitors generate high current surges that can adversely affect circuit performance in such applications. These transients, while very brief in nature, can dramatically exceed the steady-state ratings for the contacts in a high-performance electromechanical relay.
It's an unfortunate fact of life that anything of value can - and probably will - be faked at some point. While exciting stories of forged multimillion-dollar paintings and violins might make the news from time to time, the far more pedestrian fact is that counterfeiting of small electronic components is an unfortunately thriving business, and one of enormous potential consequence when lives depend on complex electronic equipment operating as anticipated. It is of absolutely vital importance to major defense contractors and the companies that supply them, not to mention to the warfighters who rely on this equipment, that counterfeit components not make their way into the field under any circumstances.
ARLINGTON, Va. The Magnetic, Miniaturized, and Monolithically Integrated Components (M3IC), a new Defense Advanced Research Projects Agency (DARPA) program, will research miniaturized magnetic components with the goal to catalyze chip-based innovations in radar and other radio frequency (RF) systems.
