WR25X1004FTL is a surface mount resistor manufactured by Walsin. It has a resistance of 1 Mohms ±1%, a wattage of 1W, and is sized 2512 RoHS. It is a chip resistor, which means that it is a small, surface-mountable passive component, constructed of layers of conductor and non-conductor materials on a substrate. This design improves performance by increasing stability, reduced parasite inductance, immunity to environmental changes such as humidity and temperature, and providing uniform resistive properties. It is RoHS compliant, meaning it is free of Lead and other hazardous substances in order to reduce environmental impact.
