Murata Manufacturing Co., Ltd. announces an ultra-high precision version of its NCP Series This new model features precision chip both a resistance tolerance and B-constant* tolerance of less than ±1%, making it the world’s first ultra-high precision chip thermistor. These thermistors make it possible to keep detection temperature error at high temperatures to a minimum, allowing for increased design freedom..
In recent years, the miniaturization and performance improvement of electronic equipment has been accompanied by an increasingly important need for countermeasures against heat generated in circuits. Chip NTC thermistors are widely used as temperature sensing devices in equipment that tends to generate relatively high internal heat, such as mobile equipment, rechargeable batteries, and automobiles.
Current Murata chip thermistors have a resistance tolerance and B-constant tolerance of ±1%. By refining our ceramic materials and laminating processes Murata developed NCP Series models of ultra-high precision chip thermistors with both a resistance tolerance and B-constant tolerance of less than ±1%.
By using these NCP Series ultra-high precision chip thermistors, it is possible to keep detection temperature error at high temperatures to a minimum, which makes it possible to reduce the design margin for detection of anomalies caused by overheating. In addition, stable operation can be achieved at temperatures close to the application’s maximum rating. Because the NCP series enables the accurate detection of any temperature rise that exceeds the rating, it may be used with circuits with higher temperature-related performance.
