High Power Thin Film Wraparound Chip Resistor

AEC-Q200 Qualified

LINKS TO ADDITIONAL RESOURCES

PHPA series chip resistors incorporate the self passivated

enhanced tantalum nitride film to give superior moisture

resistance, ESD, voltage coefficient, and resistance stability

performance. They are designed with enlarged backside

terminations to reduce the thermal resistance between the

topside resistor layer and the solder joint on the end user’s

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.
