The WMZ11A-50S102MSU600B20-G5B PTC (Positive Temperature Coefficient) thermistor with through-hole mounting made by Tyohm is a device that is used to measure and respond to temperature changes. The device contains a temperature-sensitive ceramic material with a PTC characteristic. This means that when the temperature rises, the resistance of the device also increases. It has an operating temperature range of -40°C to +155°C, an overload voltage of 600V, and an insulation resistance of 100MO at DC500V. The device is made of a heat-resistant flame-retardant material and is RoHS compliant, meaning it meets the European Union's Directive on the Restriction of the Use of Hazardous Substances in Electrical and Electronic Equipment.
