UL Environment recently presented an Environmental Claims Validated Mark (ECV) to Positronic, which will aid power connector users in evaluating contact efficiency as it relates to energy consumption. The ECV lists the average contact resistance for Positronic’s VPB series size 16 power contacts at less than one milliohm each. This low contact resistance is achieved by use of … [Read more...]
Intel Concerned with EMI’s Effect on Cable Speed
Intel plans to introduce new technology in a few months that could keep broadband speed racing along for years with a switch to fiber optics. Why the change? Intel says today’s electrical cables are approaching speed limits due to electromagnetic interference, which can disrupt what’s being transmitted.Read more at MercuryNews.com. … [Read more...]

Electronics Experts Discuss EMI in Sudden Acceleration Incidents
When it comes to sudden acceleration, automakers claim absence of a detectable fault proves absence of design defect. Not true, said a panel of electronics experts who gathered Tuesday at the National Press Club in Washington, D.C., to demystify some of the electronics issues they say are likely responsible for Toyota – and other automakers -- sudden acceleration … [Read more...]
Selecting the Right RF Coaxial Connector and Cable
RF coaxial connectors and cables provide a vital link within the communications, EMC test and measurement, commercial and military fields. Although there are a variety of RF coaxial connectors, they are characterized by a few key parameters. An article in Dataweek shows how these characteristics, along with connector durability and cost, must be considered in light of the … [Read more...]
