What is negative temperature coefficient?
A negative temperature coefficient (NTC) refers to any physical value that decreases as the temperature increases or vice versa. In electronics, NTC usually refers to a material’s decreasing resistance as the temperature rises. This article examines how NTC device performance is quantified and compares with other technologies like resistance temperature detectors (RTDs) and positive temperature […]
