Product Description


LPTC-500 Linear PTC Thermistor 500 Ohm For Transformer Compressor Motor


Descaription Of The Linear PTC Thermistor


Various types of KTY and LPTC temperature sensor chip structures are based on the principle of diffusion resistance. The main component is silicon, which is inherently stable and has an actual online linear temperature coefficient within the measurement range, ensuring high accuracy of temperature measurement. Therefore, this class has the characteristics of "high precision, high reliability and stability, and positive temperature coefficient".

LPTC-Chips***LPTC chip-----used to make in-line chip for sensor. -----Crystal oscillator compensation chip. The chip resistance value depends on the user's parameters. The chip electrode is a Ni-Sn composite electrode with high reliability and good solderability. It is characterized by accurate temperature measurement, small size and rapid response. Its performance characteristics are that according to the temperature change within the measuring range -55℃ to +175℃, the resistance value is roughly linearly changed from about 300Ω to 2000Ω.



Application Of The Linear PTC Thermistor


LPTC silicon temperature sensor is widely used in some special fields. For example, it is mainly used in temperature measurement and control systems in automobiles (oil temperature measurement in oil modules, temperature measurement and transmission of diesel injection systems, and engine cooling systems); in climate control system industry, it is mainly used in overheat protection, heating control System, power supply protection, temperature control of color printing equipment in the field of solar water heater temperature measurement, automotive oil temperature measurement, engine cooling system, engine overheat protection, industrial control system overheat protection, heating control system, power supply protection, etc. In compressor manufacturing, transformers, household appliances and other industries, it is also suitable for temperature measurement of various medium industrial pipelines and equipment in small spaces. Automotive oil temperature measurement, oil module, diesel injection system, transfer temperature measurement, engine cooling system.
