Working Principle

The CMF5040R000FHEK is a through hole resistor, which is designed for sensing saturation condition and limiting supply current in power-conversion applications. It is designed to limit the total amount of current supplied by an electrical circuit or device. The resistor is constructed from high quality materials, which makes it able to withstand large surges of current without any damage or deterioration.The resistor consists of a length of nichrome wire, which is wound around an insulating material in order to form the core of the resistor. The core is then encased with a highly reliable material in order to maintain its stability in high temperature environments.When the current flowing through the resistor reaches its limit, the internal resistance will increase, which will reduce the amount of current which can be supplied by the underlying circuit. This will act as a protection to the underlying electronic components and circuits, which will prevent them from being damaged or destroyed by excessive current.The CMF5040R000FHEK also features low external demagnetization, which provides excellent temperature stability. This means that the resistor’s internal resistance will remain constant regardless of significant temperature changes. This makes it ideal for use in temperature sensitive applications.
