Inductors are components that can convert electrical energy into magnetic energy and store it, and are widely used in various electronic devices, such as filters, oscillators, transformers and so on. They play the role of energy storage, filtering, oscillation, etc. in the circuit.
Thermistors are sensor resistors whose resistance value changes with temperature. According to the different temperature coefficients are divided into Positive Temperature Coefficient thermistor (PTC thermistor, that is, Positive Temperature Coefficient thermistor) and Negative Temperature Coefficient thermistor (NTC thermistor, that is, Negative Temperature Coefficient thermistor)
