Characteristics
◎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.
