The WMZ12A-85A70RMUU025B3.5-G6B is a PTC thermistor manufactured by Tyohm. It is a through-hole, RoHS-compliant electronic part that can be used for temperature control, heat sensing, and other temperature-related tasks. The thermistor has a positive temperature coefficient, meaning that its resistance increases as the temperature rises. It has a maximum operating temperature of 85°C, and its resistance is typically 25O at a temperature of 25°C. The maximum current it can handle is 3.5A and it is encapsulated in a G6B package.
