NTC thermistors (Negative Temperature Coefficient thermistors) are resistors whose resistance decreases as their temperature increases.  These components are made from semiconductor materials that change resistance with temperature variations. Key features include high sensitivity, good stability, and fast response time, making them suitable for temperature measurement, compensation, and control applications. Due to their small size and low cost, NTC thermistors are widely used in electronic devices, household appliances, medical equipment, and automotive systems.
