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.
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
