Description

The NTC Thermistor 10K (MF52A103J3950) is a highly reliable temperature-sensitive resistor designed for accurate temperature measurement and control. With a negative temperature coefficient (NTC), its resistance decreases as temperature increases, making it ideal for sensing and compensation applications. Commonly used in Arduino projects, home appliances, and industrial systems, this thermistor offers stable performance and fast response.
