IEC Releases Corrigendum for Voltage Variations Immunity Tests Standard
The IEC recently released a corrigendum for the electromagnetic compatibility standard IEC 61000-4-34, titled “Testing and measurement techniques - Voltage dips, short interruptions and voltage variations immunity tests for equipment with mains current more than 16 A per phase.”View and download the corrigendum at the IEC Web site. … [Read more...]
Internet-Enabled Transient Generator
The TRA3000 system by EMC-Partner brings the power of the Web to the EMC laboratory. An Ethernet interface and internal Web server enable control, communication and report generation without proprietary software. A modular architecture enables on-site upgrades for any combination of ESD, EFT, surge, ac/dc dips, interrupts and variations, common mode and both ac and impulse … [Read more...]
MEMS Spread Spectrum Oscillators (2.0mm x 2.5mm)
Ecliptek Corporation expanded its EMS MEMS spread spectrum low EMI output surface mount oscillator, theEMS4 series. The EMS4, in a miniature 2.0mm x 2.5mm package, reduces EMI at the clock source instead of locations later down the clock stream, potentially eliminating the use of supplemental shielding enclosures and/or filtering components. This greatly reduces system costs … [Read more...]
EMI Shielding Gasket Product Line Expanded
Laird Technologies, Inc., recently announced the addition of three new products to its EMI Sentry™ Form-In-Place gasket family. This Form-In-Place gasket family provides EMI shielding while offering heat and humidity resistance, excellent adhesion strength, and a minimal compression set. These qualities improve reliability by increasing the durability and longevity of … [Read more...]
Next-Generation Bus Converter with Integrated EMI Filter
Emerson Network Power recently enhanced its dc-dc bus converter portfolio with the release of the ATC250. The company says the high-density, dual-input converter offers board manufacturers a ruggedized, compact solution for generating on-board power in high-density AdvancedTCA® (ATCA®) environments and other space-constrained systems that typically employ distributed power … [Read more...]
Movement to Tighten Up Regulations on EMI above 1GHz Could Be Spreading
High-frequency EMI radiated by electronic devices, noise above 1GHz, is attracting increased scrutiny, reports Nikkei Electronics Asia. Revisions to EMI standards have expanded the scope of regulated frequencies into the GHz waveband. EMI standards are getting increasingly tough with recent revisions, striving to minimize interference in the GHz communication wavebands used by … [Read more...]
Liquid Metal CPU Cooler Reduces EMI
The Danish company Danamics ApS recently announced its first liquid metal product, the LMX, a new CPU cooler. The cooler uses the air to cool the CPU, but the “secret sauce” lies hidden within the heat pipes: liquid metal. The LMX features improvements over the previous model, including the reduction of electromagnetic interference by 1,000 percent over their earlier product, … [Read more...]
Aircraft, Satellites Could Use Nanotubes for EMI Shielding
Aerospace and aircraft companies as well as the military have been challenged to find ways of effectively shielding sensitive electronic equipment, such as radar and radios from electromagnetic interference without adding a lot of weight to aircraft and satellites (the more massive they are, the more fuel they need to stay in the air or achieve orbit, respectively). Whereas EMI … [Read more...]
Unmanned Chopper Finds Improvised Explosive Devises
The U.S. military is testing an unmanned helicopter that can detect electromagnetic emissions from Improvised Explosive Devises (IEDs). Roadside bombs have long represented the greatest killer of soldiers in Iraq and Afghanistan, but there's hope beyond the sturdy little demolition bots that already work with their human handlers. The Pentagon now has two aerial drones on the … [Read more...]
