High Power Thin Film Wraparound Chip Resistor
PHP series chip resistors are 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.
