Patent ID: RE39660

Claim:
A surface mounted four terminal connection current sensing resistor for Kelvin type measurement comprising , ; a flat metal plate made of a resistive alloy having opposite side surface portions, a pair of high conductivity conductive metal terminal plates each secured welded to a separate side of the resistance plate with a high thermal conductive dielectric cement and supported by the resistive plate , a slot inserted cut transversely in the terminal plates creating four separate pad portions, said slot set to a partial depth that determines the best stability of resistance for sensed voltage drop over the resistor, said pad portions terminal plate being split into a current pad and a sense pad with each pad portion comprising terminal connection areas; said current pad portion having a length greater in a direction from said slot than the corresponding length of said sense pad portion, said sense pad portions being enabling a measurement of voltage drop proportional to the value of current flowing between the said current pads and resistive to drifts in electrical measurements created by temperature rises that occur due to pluses of high power or high to changing ambient temperatures.
