摘要： A current sense resistor and a method of manufacturing a current sensing resistor with temperature coefficient of resistance (TCR) compensation is disclosed. The resistor has a resistive strip disposed between two conductive strips. A pair of main terminals and a pair of voltage sense terminals are formed in the conductive strips. A pair of rough TCR calibration slots are located between the main terminals and the voltage sense terminals, each of the rough TCR calibration slots have a depth selected to obtain a negative starting TCR value observed at the voltage sense terminals. A fine TCR calibration slot is formed between the pair of voltage sense terminals. The fine TCR calibration slot has a depth selected to obtain a TCR value observed at the voltage sense terminals that approaches zero. The resistor can also have a resistance calibration slot located between the pair of main terminals. The resistance calibration slot has a depth selected to calibrate a resistance value of the resistor.

摘要： A heat spreader for a resistive element is provided, the heat spreader having a body portion that is arranged over a top surface of the resistive element and electrically insulated from the resistive element. The heat spreader also includes one or more leg portion that extends from the body portion and are associated with the heat sink in a thermally conductive relationship.
