ELECTRONICS: TT electronics IRC has developed a highly stable low resistance chip resistor. Designated the LRF3W-MIL Series, the chip resistors utilize high reliability thick film materials and are available with screening to MIL-PRF-55342 or customer drawing. The chip resistor package includes an uninterrupted 2-pad termination on the long sides of the resistor, maximizing thermal transfer and improving reliability.
Resistance for the LRF3W-MIL Series chip resistors ranges from 0.003 to 1.0Ω, with a rated power of 3W at 70C. Absolute TCRs are to ±100ppm/C, ±250ppm/C, and ±500ppm/C, while available absolute tolerances are to ±1, ±2, ±5 and ±10 percent. Operating temperature ranges from -55 to +150C.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
