PTC Thermistor

PTC Ceramics, positive temperature coefficient functional ceramics, is a new type of thermistor  and could be made into component with relevant temperature and shape. Its resistivity is going up along with the increasing of temperature to reduce the current and keep the inside ceramic plate on a constant temperature. The main element of PTC thermistor is BaTiO3,(PbSrCaBa)(TiSnO3 and V2O5. Via dopeding and modifying, it has constant temperature ,no over-heat ,little power expenditure and safety . Hence, its application covers widely  in electrical industry, medical area, home appliance , oil industry and auto test ,etc.
