PTC thermistor can be ideal devices for temperature detection, monitoring, indicating, limiting and over
(excessive) temperature protection, due it switches at one particular temperature.
PTC (positive temperature coefficient )thermistor switches at one particular temperature. Making use of the characteristics that the resistance of PTC thermistor increases sharply above curie temperature, when ambient temperature increases abnormally, protective circuit installed PTC thermistor will turn on or cut off loop through resistance changing, achieving thermal protection purpose. PTC thermistor protect such equipment and components as motors, transformers, power transistors and thyristors against over-temperature. A PTC thermistor is less expensive than a thermostat, and its switch temperature can be more accurately specified. It is also smaller and easier to design-in to electronic circuitry. Therefore PTC thermistor can be ideal devices for temperature detection, monitoring, indicating, limiting and over (excessive) temperature protection.
Typical Application of PTC Thermistor for Temperature Protection and temperature limiting sensors
·Limit temperature measurement of Industrial electronics application.
·Power supplies, switch power supply.
·Home appliances, such as dish washers, washing machines, ironing machines, electric cookers, etc.
·Electronic data processing and communications engineering (DC/DC converters).
·Motor windings overheating Protection.
·Semiconductor heatsinks, enclosure panels, temperature-limited transistors.
