Murata Develops World’s Smallest 008004-Inch NTC Thermistor

What happened

Murata Manufacturing has developed the NCU01 series, an 008004-inch negative temperature coefficient (NTC) thermistor measuring just 0.25 × 0.125 mm, described as the world's smallest. Compared with the company's previous smallest 01005-inch product, the new component reduces mounting area by approximately 60% while maintaining equivalent temperature-sensing performance, with both resistance and B-constant tolerances specified at ±1%. The ultra-compact thermistor targets densely integrated devices including smartphones, wearable electronics, IC packages, and SiP modules, allowing temperature sensors to be placed closer to heat-generating components. Murata plans to begin sample shipments in October 2026, followed by mass production in 2027; the initial lineup will include 100 kΩ and 10 kΩ resistance variants, with additional options introduced progressively.
