The 1812 surface-mount PTC resettable sensor features a full-faced termination design. The Overcurrent Circuit Protection Guide provides a tutorial on the design characteristics and different technologies of both a Positive Temperature Coefficient (PTC) resettable device and fuse. The guide provides a glossary of PTC terms and includes typical PTC ratings for voltage, current, temperature, and other parameters. Applications such as computers and peripherals for PTC resettables are also included.

More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
