Ultra-Small Size, Precision Temperature Monitoring for Consumer & Industrial Applications
The MF72-0402 series is an ultra-compact NTC thermistor (Negative Temperature Coefficient) packaged in standard 0402 (1005 metric) SMD dimensions, designed for applications requiring precise thermal sensing in confined spaces. With resistance values ranging from 4.7kΩ to 470kΩ at 25°C, and B constants up to 4250K, these thermistors are ideal for modern portable electronics, wearable devices, IoT sensors, and battery temperature control.
