Current Sense Resistors
Not far off from normal resistors, current sense resistors feature very low resistance rating and high-power rating.
Also known as shunt resistors, these devices are used to gauge the flow of current. Known resistor value (R) is placed in a current conducting path so that the entire current (I) flows through the resistors. They are designed for low resistance to minimize power consumption and to eliminate the risk of short circuits which are likely to damage other components.
In the design of electronics, shunt means providing a different path to the circuit. Shunt resistors create a very low resistance path for the current to pass from one circuit portion to another circuit portion. At this path, whenever a current passes through the low resistance region, irrespective of the amount of current flow, one can measure how much current is flowing through the circuit.
Vishay WFC & WFCP Metal Foil Current Sense Resistors is an optimal solution for designers looking to improve performance in limited spaces. The age old question of space-vs-quality has finally met its match.
