    • A thermistor is disclosed, which comprises a resistance element having upper and lower surfaces and showing a resistance varying characteristics according to the change of temperature; first and second conductive layers formed on the upper surface of the resistance element and engaged to each other with a non-conductive gap interposed therebetween; first and second electrodes formed on the lower surface of the resistance element and electrically separated from each other; a first connector for electrically connecting the first conductive layer to the first electrode; and a second connector for electrically connecting the second conductive layer to the second electrode. Thus, the thermistor has a structurally point-symmetric shape, so it is possible to prevent the Tombstone phenomenon, caused by an asymmetric structure. Since the conductive layers having opposite polarities are engaged to each other with the non-conductive gap therebetween, the flow of current is increased and the resistance of the thermistor is decreased.
    • 公开了一种热敏电阻器,其包括具有上表面和下表面的电阻元件,并且根据温度变化显示出电阻变化特性; 第一和第二导电层形成在电阻元件的上表面上并且彼此接合,并具有插入其间的非导电间隙; 第一和第二电极形成在电阻元件的下表面上并彼此电分离; 用于将所述第一导电层电连接到所述第一电极的第一连接器; 以及用于将所述第二导电层电连接到所述第二电极的第二连接器。 因此,热敏电阻具有结构上点对称的形状,因此可以防止由不对称结构引起的墓碑现象。 由于具有相反极性的导电层之间具有非导电间隙而彼此接合,所以电流的流动增加并且热敏电阻的电阻降低。
