The WMZ11A-75L502MAP600B3.75-G6B with PTC Thermistors Through Hole RoHS manufactured by Tyohm is an electronic component designed to help regulate the current and potential being supplied to circuits and electronic systems. This particular component is a PTC (positive temperature coefficient) thermistor, which acts as a resistor in circuits, but also adjusts the amount of current or voltage depending on the temperature. It is a through-hole component, meaning the component is mounted by leads through pre-drilled holes in the PCB for connections to the circuit board. This particular component is RoHS compliant, meaning it complies with the European RoHS (Restriction of Hazardous Substances) directive which restricts the use of certain hazardous substances in the manufacture of electronic and electrical equipment.
