Current-sensing techniques are intrusive, meaning that somehow they will affect the system performance. It’s usually necessary to insert “something” in the middle of the path that goes from the power source to the load through which the current that we need to monitor flows.

Resistor engineers designed to mitigate these losses must use current sensor resistors with low resistive values. This is the greatest complexity of this method, choosing the better resistor to obtain a balance between precision, energy loss, and costs in the current sensor

Resistors have traditionally been manufactured by a variety of methods and technologies, including metal and metal-oxide film, metal foil, carbon, wirewound, and thick-film methods. Each has specific characteristics that make them more or less suitable for high-temperature applications. Resistor degradation at a high temperature can vary from a small resistance change over time to a catastrophic change in resistance, exhibited by either becoming open circuit or, in some cases, a short circuit.

The MFC series uses metal foil on ceramic technology, which combines the heat spreading properties of a ceramic substrate with the surge tolerance of a bulk metal alloy resistance element. This, in turn, offers better surge tolerance than thick-film options and lower self-heating levels than thick-film or metal strip resistors, well-suited for automotive, industrial, and medical applications.
