  • Brief Introduction of PTC Thermistor
    Thermistor can be classified into 2 category, PTC thermistor and NTC thermistor, according to its resistance-temperature characteristics. PTC, abbreviation of Positive Temperature Coefficient. NTC, abbreviation of Negative Temperature Coefficient. PTC thermistor is classified into 2 type
  • Hot tips on IC temp sensors
    a positive temperature coefficient (PTC). A PTC means resistance rises as the temperature climbs. Other materials may have a negative temperature coefficient (NTC). The resistance of NTC material falls as the temperature climbs. The most common device used to sense temperature is the thermistor
  • PPTC Design Considerations for Automotive Circuits
    and overloads. Current limiting can be accomplished by using a resistor, fuse, switch or PTC (positive temperature coefficient) device. Resistors are rarely an acceptable solution because an expensive high-power resistor is usually required, although they are used occasionally for very low power loads
  • Fundamentals of Resettable Functionality in PPTC Devices
    due to excessive current or heat is the primary function of many circuit protection technologies. In the past, this protection took the form of a fuse or fusible link, but in many of today's applications resettable devices such as polymeric positive temperature coefficient (PPTC) devices, ceramic PTC
