The WMZ12A-75S222NUP600B3.5-G5B is a through hole PTC thermistor with RoHS (Restriction of Hazardous Substances) compliance manufactured by Tyohm. This thermistor is designed with a resistance of 75 ohms, positive temperature coefficient, and a tolerance of +/-22%. Its voltage rating is 600V AC/DC and the power rating is 3.5W. The thermistor is more robust than other similar components due to its PTC (Positive Temperature Coefficient) design, which increases its resistance as the ambient temperature rises. In addition, the unique construction of the component allows for easier installation and cost-efficiency in comparison to other alternatives.
