Workshop of high quality and high performance NTC Thermistor
We have the unique process and leader core technology with
proprietary intellectual property rights of ceramic powder
equipment,made of chips,high performance NTC Automatic batch
production.
We have more than 12 series of high performance NTC thermistors
automatic production line,products have the advantages of large
production,high quality,good coherence,high reliability,besides it
can be made of many kinds of NTC temperature sensors,it also can be
supplied to other factories of NTC sensors,and exported in large
quantities to overseas.
