Low Resistance Values Ideal for Portable Consumer Electronics
The CSRF Series is a surface mount current sense resistor series that utilizes foil on ceramic carrier technology. This structure allows for very low resistance values in small case sizes while maintaining good TCR. The 0402 size is available in the popular 10 milliohm value, while the 0603 size is available in values down to […]
High-performance DACs reduce board space and lower system costs
Texas Instruments today introduced a new family of digital-to-analog converters (DACs) that enables engineers to increase the accuracy and performance of programmable logic controller (PLC) I/O modules, field sensors and transmitters, and building automation systems, while decreasing overall system size and cost. The DAC8760 family is also the industry’s first to provide simultaneous voltage and […]

How to avoid errors when specifying sensor products
There are three things designers/engineers should seek to do when specifying sensor products. These are: thermal hysteresis, board mounts that are moisture sensitive, and sensors that are A/D convertible. The ability of the sensor to come back to the same output after a thermal change is called thermal hysteresis. Designers underestimate errors due to thermal […]
8 Inventions electronically inspired
Electrical engineering components are everywhere and is used in many platforms on a daily basis. Here are some things that EEs have designed and created with power, automation, microelectronics, communication, and computer engineering techniques. The Hand of Man The perfect way to crush cars by hand was created in 2007, by Christian Ristow, an artist […]
Six useful videos about power supplies
There are some useful videos on power supplies, ranging from computer usage to fundamental background in circuit design. This is my list of videos that were brief and impressive. Converting computer ATX power supply to lab bench power supply was a nice video that gave background information on how and why to wire the supplies […]
Three design tips for power converters
Designing a power converter requires three key elements when producing a quality product. A power converter needs component de-rating, calculation for the power factor, and EMI/EMC (electromagnetic interference/compatibility). Without these requirements, the design may not work at all. De-rate components is one of the most common steps in power converter designs. Engineers often stop after […]
Video: NI’s myGrid/myDAQ Demonstration
Hello, I am Natasha Townsend, Associate Electrical Engineering Editor at Design World. In this DAQ series, National Instruments has provided its myDAQ and myGrid minisystems as a demonstration of how DAQs work in everyday applications. The intent and purpose of the minisystems platform is to present engineering theory and principals into real life applications. The […]
