The WMZ11A-75S751XSP600B7-G5B is a through-hole RoHS compliant PTC thermistor made by Tyohm. It is a self-regulating, temperature-sensing, and feedback device that can be used as an over-temperature protection, or temperature-sensing switch. It is commonly used in motor control, HVAC, lamps, and other industrial applications. The low temperature set-point is -75°C and the high temperature set-point is +75°C, giving it a temperature hysteresis of 150°C. The maximum continuous working current is 600 mA while the power dissipation is 5 watts.
