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.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
