The WMF21-5D11MPUP8CB4 with NTC Thermistors Through Hole RoHS, manufactured by Tyohm, is an electric component that contains a NTC (Negative Temperature Coefficient) thermistor. This thermistor is a type of resistor which changes its resistance value with respect to changes in temperatures. The RoHS (Restriction of Hazardous Substances) compatibility ensures that the part does not contain potentially hazardous material that could affect humans and the environment. The WMF21-5D11MPUP8CB4 has a through-hole mounting which allows for the component to be easily mounted onto the PCB by soldering. This part is designed to provide accurate temperature sensing in a wide range of applications.
