High-current, four-terminal shunt resistors now in 1216 and 4026 sizes
Low resistance values are important for high-efficiency current sensing in that lower values mean less wasted power on the current sensing measurement itself. But sensing low resistance values becomes challenging because of lead resistance. Using a four-terminal shunt resistor eliminates the detrimental effects of lead resistance on the current sensing measurement operation. Stackpole recently added […]
