PTC (Positive Temperature Coefficient) thermistors are temperature sensors characterized by their increase in resistance as temperature rises. These thermistors are commonly used in overcurrent protection, degaussing circuits, and as heating elements.
PTC thermistors provide self-regulating heating, making them suitable for applications like motor protection, circuit protection, and temperature compensation. Their reliable performance and durability enhance the safety and efficiency of electronic systems.
Leading manufacturers like EPCOS, Littelfuse, and Amphenol Advanced Sensors offer a variety of PTC thermistors designed for various industrial and consumer applications. Their robust design ensures high reliability and longevity.
