Murata<\/a><\/strong> announces the development of the world’s smallest 008004-inch size (0.25mm \u00d7 0.125mm) NTC thermistor, the NCU01 series. Compared with Murata’s previous smallest 01005-inch size (0.4mm \u00d7 0.2mm) product, the new series reduces mounting area by approximately 60% while achieving equivalent temperature-sensing performance, with resistance tolerance of \u00b11% and B-constant tolerance of \u00b11%. Its ultra-compact size enables temperature sensing to be positioned in increasingly restricted spaces and closer to heat-generating components, supporting more accurate and responsive thermal monitoring in smartphones, wearable devices, and other densely integrated electronic devices.<\/p>\n\n\n\n

Murata plans to begin sample shipments in October 2026 and mass production during 2027. The lineup will be expanded progressively, beginning with 100k\u03a9 and 10k\u03a9 resistance values.<\/p>\n\n\n\n

As electronic devices continue to become smaller and more sophisticated, component density on circuit boards and inside modules continues to increase. As a result, mounting space for electronic components is limited, making it difficult to place NTC thermistors close to heat-generating components. If a thermistor must be placed farther from the heat source, the measured temperature can differ from the actual component temperature, while rapid temperature changes may also take longer to detect. <\/p>\n\n\n\n

This creates a demand for smaller NTC thermistors that can be positioned closer to critical components without consuming valuable board space. However, continued miniaturization makes high-precision processing and manufacturing more difficult, making it more challenging to maintain consistent sensing characteristics. For NTC thermistors, tight resistance and B-constant tolerances are critical to enable stable temperature sensing. <\/p>\n\n\n\n

Murata addressed these challenges through its proprietary ceramic materials technology, high-precision processing, and optimization of the component structure and manufacturing process to develop the world’s smallest 008004-inch size NTC thermistor. Despite its significantly smaller footprint, the new NCU01 series maintains the \u00b11% resistance and B-constant tolerances achieved by Murata’s previous 01005-inch size product.<\/p>\n\n\n\n

By reducing the mounting area by approximately 60%, the NCU01 can be placed in locations that are difficult to accommodate with larger thermistors, including closer to heat-generating components. This can help reduce the temperature difference and detection delay associated with more distant measurement points while contributing to the stable operation of electronic devices with high-density component layouts.<\/p>\n\n\n\n

Primary applications include temperature monitoring on circuit boards in smartphones and wearable devices, as well as in integrated circuit (IC) packages and system-in-package (SiP) modules.<\/p>\n","protected":false},"excerpt":{"rendered":"
