Ohmite Manufacturing (Arlington Heights, IL) adds a new non-inductive option to their Maxi-Mox series of thick-film axial terminal resistors. This alternative to the standard configuration is ideal for high frequency applications and controls. Features include a resistance range of 250 ohms to 1 Teraohm.
NK Technologies (San Jose, CA) introduces APT Series Power Transducers. The APT measures three phases of current and voltage and produces an industry standard analog signal proportional to the watts used. The monitor uses current transformers to measure the amperes, and the line voltage connects directly to the transducer, up to 600 VAC.
Linear Technology Corporation (Milpitas, CA) announces the LTC3784, a high-power, two-phase, single-output synchronous step-up DC/DC controller that replaces rectifying boost diodes with high efficiency N-channel MOSFETs. This device can produce a 24V output at 10A from a 12V input at up to 97% efficiency without any heat sink.
Several Powerex (Youngwood, PA) SiC Modules have now been certified RoHS (Restriction of Use of Hazardous Substances) compliant. RoHS regulations ban new electrical or electronic equipment containing more than agreed upon levels of specific substances, including lead....
Scientists have created a microbattery that packs twice the energy compared to current microbatteries used to monitor the movements of salmon through rivers in the Pacific Northwest and around the world. The battery, a cylinder just slightly larger than a long grain of rice, is certainly not the world's smallest battery, as engineers have created batteries far tinier than the width of a human hair.
Meeting the unrelenting demands of tight design schedules will always be a challenge for developers of board-mounted power architectures with point-of-load (POL) DC-DC power modules. As board complexities grow—driving drastic increases in the number of POL power rails—designers must rapidly respond....
Phoenix Contact (Middletown, PA) introduced RIFLINE Complete, a modular ice cube-style relay system with a broad range of accessories. The system is available as either completely assembled modules, which can save assembly time and labor costs, or as individual components, to
Molex’ (Lisle, IL) Mega-Fit wire-to-board, mid-range power connector is presented as filling a significant power void in today’s interconnect marketplace by delivering 23 A in a small 5.7-mm footprint. The connectors are appropriate for
MicroPower Direct’s (Stoughton, MA) MB5000RU Series delivers 50 W of isolated, tightly regulated output power in a 1 x 2 x 0.4 inch case. The converters are designed for applications requiring very wide inputs, compact size, high
Coilcraft (Cary, IL) introduces the XAL1010 Series of high-temperature, shielded power inductors which combines excellent current handling and exceptionally low DC resistance in a rugged, molded package. Features include thirteen inductance values from 0.22 to 15 µH.
Studio diip — a company specializing in image-recognition products — developed the "Fish on Wheels", a self-driving car for fish. The system uses a webcam, batter power Beagleboard, and an Arduino controlled robot vehicle, and the vehicle basically turns in whatever direction the fish swims.
The concept of energy harvesting has been around for as long as windmills and waterwheels were used to harness energy. In the last decade, the possibilities of using low-power harvested energy have greatly expanded in the industrial market as devices became smaller, autonomous and required less power.
Many end applications — such as IP phones, motor control circuits, active clamp switches, and load switches — need to offer higher energy efficiency in a smaller footprint in order to meet manufacturers’ demands. Fairchild Semiconductor (San Jose, CA) developed the FDMC86xxxP series of P-channel PowerTrench MOSFETs....
Advanced Power Electronics Corp. (San Jose, CA) is introducing a new current mode step up converter for small, low power applications. The input voltage of the APE1913-3 converter can range from 2.6V to 5.5V, while the output voltage can be adjusted up to 27V.
Wind power has been booming in Germany since the beginning of the energy transition. However, the voices of critics have been growing along with the increasing number of wind turbines. Citizens' initiatives in Lower Saxony and Baden-Württemberg for instance have founded a umbrella association meant to provide local groups with a political say.
Micro-machining could be used to create almost flat, Fresnel lenses, that boost the electrical efficiency of solar panels, according to researchers in China. Fresnel lenses were invented by French engineer and scientist Augustin-Jean Fresnel in the early nineteenth century....
Do you ever feel like your fish is jealous of the cat and dog who can walk freely about the house just because they have the ability to “breathe oxygen”? Have you caught your fish eyeing the parrot and his high flying, free-wheeling ways? Is he jealous of the hamster in the ball who gets to roll around the house?
