Legamaster electrical components German Legamaster models Legamaster prices

Legamaster electrical components are sensor resistors whose resistance changes with temperature. Based on different temperature coefficients, they are classified into positive temperature coefficient thermistors and negative temperature coefficient thermistors. The resistance of a positive temperature coefficient thermistor increases as temperature rises, while the resistance of a negative temperature coefficient thermistor decreases as temperature rises; both belong to semiconductor devices. Legamaster electrical component principle: Light emission principle of laser diodes: The P-N junction in a laser diode is formed by two doped gallium arsenide layers. It has
