One watt current sense chip resistors
There is an on-going trend to smaller, portable and more functional devices in the consumer electronics world. This is particularly true in the current sense chip resistor market where power control architectures are being downsized even as the functionality is being enhanced.
High current four terminal shunt resistors
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.
