Software with the fastest execution time isn’t necessarily the greenest. There once was an assumption among computer programmers that a faster program is also an energy efficient program. The idea transmuted over to software programming languages—surely a faster language was a greener one, the logic went. That all changed in 2017 thanks to a group […]
Low-cost 30-W dc-dc converter features 4:1 input range
30-W dc-dc converters in the new THL 30WI series come in a standard 1×1-in footprint. This next-generation product greatly improves the “cost/performance” ratio in the 30-W, 1×1-in industry standard product area. Combined with safety approvals to the latest IEC/EN/UL 62368-1 standards, the product is a candidate for mobile equipment, instrumentation, distributed power architectures and industrial […]
World’s highest-power MEMS switch handles 10 A
The new MM9200 is the world’s first micromechanical power switch capable of handling 10 A in a miniature 5×5-mm surface-mount package. With its ultra-low 0.010-Ω contact resistance, the new MM9200 is said to be the lowest-loss and highest power capable micro-mechanical switch ever created. The MM9200 targets a wide range of applications including industrial automation, […]
SMT “auto” blade fuse holders feature low insertion force
A full line of fuse clips and holders now includes low insertion force, reliable and compact automotive blade fuse holders for Maxi style automotive blade fuses. Manufactured to ensure secured positioning during soldering, these holders support Voltage up to 500 Vac and 40 A of current, as well as fully insulated clips to protect fuses and reduce […]
Test gear speeds EMC tests under real driving conditions
New test gear supports automated testing with simulation of real driving conditions while covering typical automotive standards. The AVL PUMA 2 automation controls the test cycle and stores the measured data, in synchronization with the R&S ELEKTRA EMC test software to exchange information between the testbed and the EMC measurement equipment. The ELEKTRA software has […]
Why you don’t need a variable-speed drive to change a fan’s speed
To engineers schooled in modern motor control methods, it may be hard to grasp why three-speed fans designed to move air around in a room can be inexpensive. After all, these fans are powered by as motors, and the go-to method for changing the speed of industrial ac motors is via variable-frequency drives. VFDs work […]
5G LPWA ALT1350 chipset boasts ultra-low power consumption
The ALT1350 is the world’s first cellular LTE-M/NB-IoT solution to enable additional LPWA communication protocols, as well as satellite connectivity (NTN), in a single chipset, opening the door to further innovation in the connected world. The ALT1350 by Sony is the most advanced cellular IoT solution on the market, with an architecture that resolves IoT […]
Step attenuators feature attenuation accuracy of ±5 dB
New step attenuators feature attenuation accuracy of ±5 dB, making them candidates for high-reliability applications demanding accurate adjustment of attenuation values. Additional superior performance characteristics for the step attenuators include 1 dB maximum insertion loss and a maximum VSWR of 1.4:1. These high-reliability step attenuators offer wide coverage and high power with an operating frequency […]
Temperature-compensated RF amps cover 0.5 GHz to 40 GHz
A series of temperature-compensated amplifiers address precision performance and test-and-measurement applications. Fairview’s new series of coaxial packaged, temperature-compensated amplifiers covers broadband and ultra-broadband frequencies ranging from 0.5 GHz to 40 GHz. Designs incorporate pin diode attenuation circuitry that senses and adjusts broadband gain levels and maintains a minimum gain level of 35 dB over the […]
Researchers claim to beat dendrite battery blues
Dendrites are projections of metal that can build up on the surface of lithium anodes and penetrate into the battery electrolyte, eventually crossing from one electrode to the other and shorting out the battery cell. What gives rise to these metal filaments has been somewhat of a mystery, and there has been little progress on…
