◎Glass encapsulation,capability of operating in the bad environment of high temperature and high humidity because of the glass encapsulation framework.

◎High precision of temperature testing,good stability and broad range of resistance.

◎Small size,fast response,high sensitivity.

◎ Without leads,convenient for SMT automatic installation.

Applications

◎ Automatic work faciities (such as lap-top,copycat, printer and so on)

◎ Digital equipment(such as mobile phone,PDA and etc.)

◎Rechargeable battery (lithium battery,ni-mh battery)

◎Temperature compensation of loops of instrument,integrated circuit,quartz crystal monofier and thermocouple.
