When first mandated in the 1990s, the stated objective of the EU’s Directive governing EMC was, in broad terms, that commercial and domestic equipment, and certain industrial systems, should neither cause interference or be susceptible to interference. They should not emit radiated or conducted energy at RF frequencies and they should be immune to such emissions, within … [Read more...]
DC/DC Converter with Integrated FETs Provides Power Efficiency
Texas Instruments Incorporated’s new synchronous 50-mA, 60-V SWIFT™ step-down regulator has high efficiency and low noise performance in a solution size of 125 mm2. The TPS54062 integrates both the high-side and low-side power MOSFETs, providing efficient power conversion and transient protection to noise-sensitive industrial automation and sensor control, smart meter, telecom, … [Read more...]
EU Begins Enforcement of Toy Safety Directive
The member states of the European Union will begin applying on July 20 the new measures of the Toy Safety Directive 2009/48/EC, regarding toys for children age 14 and under.The new Directive, which came into force in July 2009 and was implemented into national legislation in January 2011, brings in particular more references on chemicals by limiting the amounts of certain … [Read more...]
Ferrite Testing Reveals Significant Performance Variations
Recent empirical testing of FerriShield Ferrites shows that there is a notable increase in Ohms of impedance when compared to the exact same competitive alternative. Due to an industry‐wide shift in raw material formulation and manufacturing processes, many RFI/EMI ferrites on the market are delivering lower performance across a wide‐band frequency range. This variation is an … [Read more...]
FCC Proposes Rules Changes to Improve Wireless Coverage
The Federal Communications Commission adopted a Notice of Proposed Rulemaking (NPRM) to facilitate the development and deployment of well-designed signal boosters, which hold great potential to empower consumers in rural and underserved areas to improve their wireless coverage. Coverage gaps exist within those service areas and continue to pose a problem for residents, … [Read more...]
Electromagnetic Fields Offer Next Big Game Controller Technology
Kinect, Microsoft is working toward the next evolution in gaming control: electromagnetism. Thanks to modern conveniences like electrical outlets, light fixtures and computers, almost every building in existence is covered in electromagnetic fields. Microsoft's team of researchers has developed a device that detects a person's position in relation to these fields. By attaching … [Read more...]
Japan Disaster Hinders Supply of Crystals Commonly Used in Cell Phones and PCs
Disruptions spurred by the Japan earthquake and tsunami caused shipments of crystals to be delayed by four weeks in April. The average lead time for megahertz and kilohertz crystals rose to 12 weeks in April, up 50 percent from eight weeks in March. Unusually long lead times can lead to delivery delays and short supplies of electronic products. Delivery delays, in turn, are … [Read more...]
High Power Electromagnetic (HPEM) Threats to the Smart Grid
This paper is focused on the threats and impacts of High Power Electromagnetic (HPEM) environments on the U.S. Power Grid and further introduces the implications of making the power grid “smarter” through the introduction of additional electronics. These Smart Grid electronics may introduce additional vulnerabilities if the grid is exposed to the high power EM threats of … [Read more...]
EMC Business Bulletin – April 20, 2011 – Volume 11
EMV Show Review, Europe Market Study Offer Promising Signs There are two key indicators that the European EMC market is showing signs of steady growth this year. 1. The 2011 EMV Show At the EMV show, which took place in Stuttgart last month, the number of workshop attendees increased 15% over the last time this event was held in 2009, up from 923 people to 1082. … [Read more...]
iPad 2’s Compass Susceptible to EMI
A number of iPad 2’s parts are in short supply after the Japanese earthquake. One such component, the tablet computer’s compass, cannot be replaced with other units because it is compasses are susceptible to EMI. Also, the iPad 2's compass works in close coordination with the tablet's accelerometer and gyroscope. This makes it impossible to simply replace one manufacturer's … [Read more...]
