Abstract

Sensor and temperature compensation applications have developed into one of the more promising markets in the electronic industry. In the past, since applications were limited, the materials used were usually developed to meet the unique requirement with narrow application focus. With broader market needs, design of the materials can be done independently of the application. This is especially true for temperature sensors. Sensing and compensation circuits define general requirements, e.g. high thermistor constant, wide range of resistivity, and good reproducibility. To address these needs, DuPont has applied it's extensive thick film resistor technology base to develop an NTC thermistor series NTxx composed of 3 members: 1, 10, 100 Kohms (NT30,NT40 and NT50). The series offers high beta, and is fully blendable for both beta and R for all members. This provides design and manufacturing flexibility for sensor and temperature compensation applications. Various electrical, blendability data are presented. In addition, a method for laser trimming these materials is discussed.
