The WR06X1430FTL by Walsin is a chip resistor, or surface-mount resistor, which is typically used in electrical circuits to limit the current in a circuit so that the add-ons, such as transistors, diodes, and capacitors, do not burn out. The WR06X1430FTL resistor has a resistance of 143 ohms and a tolerance of ±1%, a size of 0603, and a power rating of 1/10 W. Moreover, it is RoHS compliant, meaning that it is made without the use of certain hazardous substances.
