Spec Sheet R501-1/2 01/99
Temperature dependence of the electrical resistance
of ISA-PLAN resistors
power derating curve
Remarks:
- Standard resistance values according to E12 with the additional values of 2 and 5
- Minimum quantity of other values on request
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.
