Power supplies and current sensing circuits have requirements that are as diverse as the end products they serve. Some applications, for example, need low TCR without requiring low values associated with metal alloy resistors. It can be challenging to find such a resistor. Thick film technology is generally used for higher sense resistor values, but they have poor […]
