NTC/PTC Thermistors & Polymer PTC Resettable Fuse (PPTC)
NTC/PTC thermistors are temperature-sensitive resistors that change their resistance based on thermal variations, used for monitoring and controlling temperature in electrical circuits. PPTC (Polymeric Positive Temperature Coefficient) fuses are resettable fuses that protect electrical circuits from overcurrents by increasing their resistance during an overload, automatically resetting when normal conditions are restored.
