MFR100FRE52-52R3

Through Hole Resistors (also known as leaded resistors) are passive components comprised of a resistive element, two terminal leads, and an encasing body. The MFR100FRE52-52R3 is part of Vishay\'s Metal Film Resistors series of through hole resistors. It features thin film technology for high accuracy and performance, low noise and low power. It is designed for applications such as medical equipment, robotics, industrial equipment and control, automotive, and defense.

The part number of MFR100FRE52-52R3 indicates its power rating as being 0.1 W, and its tolerance rating with ±5%. The power rating of 0.1 W is, in general, the maximum power that the MFR100FRE52-52R3 can dissipate without burning out. The tolerance rating specifies the maximum deviation from the nominal value, expressed as ±x%, of the resistor. It also has the following specifications: temperature coefficient (TCR): ± 100 ppm/K, resistance value: 1 kΩ, and voltage rating (VR): 350 V.

The MFR100FRE52-52R3 has a compact housing with the dimensions of 4.5 mm W × 12.0 mm L × 7.5 mm H. Its housing is made of heat resistant fourth-generation glass-filled polymide which has mechanical and electrical advantages such as excellent energy absorption, steady resistance to high temperatures (up to 250°C) and superior dielectric strength withstanding DC voltage of up to 350 V. The two terminal leads are formed from copper strips which are aluminium-plated for additional corrosion protection. The two terminal leads are used to provide a connection between the resistive element and the external circuit.

The MFR100FRE52-52R3 utilizes thin film technology, as its name implies, wherein the resistive element is built up in successive layers. It allows for the production of high accuracy and low noise resistors with tight tolerances of 0.5% and a low temperature coefficient of variation at ±100ppm/K, as compared to carbon and wirewound resistors which usually have higher tolerances and higher temperature coefficient of variation. In addition, the MFR100FRE52-52R3 also has significantly lower noise than carbon or wirewound resistors.

The working principle of MFR100FRE52-52R3 involves two main processes: first, the application of an electric current across the resistive element; and second, the conversion of input energy into thermal energy due to the resistance in the resistive element. The amount of thermal energy dissipation is determined by the power rating of the resistor, as when the resistor is dissipating too much power, it becomes increasingly hot until it eventually burns out. The MFR100FRE52-52R3 is designed to prevent this by having a power rating of 0.1 W which is within the safe range of operation.

The MFR100FRE52-52R3 is ideal for applications with strict space and power requirements, such as in medical equipment, robotics, industrial equipment and control, automotive, and defense. With its thin film technology, low noise and low power, it is the perfect choice for high accuracy and performance projects. This high performance, combined with the excellent electrical and mechanical properties of the fourth generation glass-filled polymide housing, make the MFR100FRE52-52R3 an essential component for many applications.
