nwl electrical components, Germany nwl models, nwl prices

nwl electrical components are sensor resistors whose resistance changes with temperature. According to different temperature coefficients, they are divided into positive temperature coefficient thermistors and negative temperature coefficient thermistors. The resistance of a positive temperature coefficient thermistor increases as the temperature rises, while the resistance of a negative temperature coefficient thermistor decreases as the temperature rises; both belong to semiconductor devices. nwl electrical component features 1. The function of a varactor diode is based on the principle that the capacitance between PN junctions is variable; it is a semiconductor device used as a variable capacitor in high-frequency tuning, communication, and other circuits.
