The PHP01206E1000BST3 is a 100R 1W surface-mounting high power Chip Resistor with nichrome thin film wraparound element, alumina substrate and wraparound lead (Pb)-free solder SAC-305 termination. It is designed with enlarged backside terminations to reduce the thermal resistance between the topside resistor layer and the solder joint on the end users circuit board. Actual power handling capability is limited by the end user mounting process. As with any high power chip resistor the ability to remove the generated heat is critical to the overall performance of the device.
