Murata's New NTC Thermistor Is 0.25 mm Long, Small Enough to Sit Right Next to the Hot Spot Temperature sensing on a crowded board usually means putting the thermistor wherever there is room, not where the heat is. Murata has announced the NCU01 series, an NTC thermistor in the 008004-inch size (0.25 mm × 0.125 mm, called 0201M in metric), which the company says is the world's smallest based on its own research as of 19 October 2026. Compared with its previous smallest 01005-inch… |

How to Build an IoT Indoor Weather Station Using CircuitDigest Cloud "Is it going to rain, or should I leave the windows open?" we would have asked ourselves numerous times. Now the weather is clear, but sometimes the rain will suddenly start pouring. The standard weather forecast application may give you accurate forecasts near the airport or other places, which are kilometres away from us, but it will not give us accurate forecasts… |
