ELECTRONICS: Electronic components distributor Digi-Key Corp. now stocks Stackpole Electronics’ RNCS series of passivated Nichrome chip resistors, a low-cost alternative for expensive and hard-to-find tantalum nitride chip resistors. Digi-Key is stocking the most commonly used values of this series in sizes 0603, 0805 and 1206 packaged on 1K reels. These products are also available in cut tape quantities. A smaller quantity can also be ordered for same-day shipment on a custom Digi-Reel®. The RNCS series employs a special manufacturing process to ensure high precision, ultra-stable performance and long life in the harshest environments. In moisture comparison testing, the lead-free and RoHS-compliant RNCS series outperformed Nichrome chip resistors and demonstrated the anti-corrosive claims characterized by tantalum nitride resistor products.
The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
