This resistor has been developed especially for current

sense applications in SMD-power modules.

The PMA has been designed for flip-chip mounting on the

pc-board. All standard soldering processes like reflow-,

infrared-, vapor phase-, dip- and wave-soldering can be

used.

The heat which is generated by the measuring current is

conducted very efficiently to the pc-board via the heat

conductive substrate and the solder joints.
