FMP100FRF52-549R

Through hole resistors, in general, are electro-mechanical component used in electrical circuits to power electronic components. The most common type of through hole resistors are axial resistors, which are cylindrical components that are either directly soldered onto a printed circuit board or inserted into a holder or socket. The FMP100FRF52-549R is a very specific type of through hole resistor, which is used in a variety of applications.

Applications

The FMP100FRF52-549R has a few main applications in circuits, including providing electrical protection from overloads, clamping/limiting voltage overshoot, and circuit isolation. This resistors series is usually designed to handle high-working currents, which make it great for high-power applications such as motor controllers, aerospace systems, automotive systems, and more. Due to its ability to handle high current and its reliable performance, it is also commonly used in industrial and commercial applications like HVAC systems and power management systems. It is also designed to be used in high-temperature applications (up to +125°C).

Working Principle

The FMP100FRF52-549R works by limiting the flow of electric current through it. The resistor operates in three distinct modes: resistance, nonlinear resistance, and symmetrical impedance. Resistance, or ohmic mode, is the primary mode of operation; when current passes through the resistor, its resistance reduces the current and the resistor dissipates the energy as heat. When nonlinear resistance is activated, the resistor’s resistance increases as the voltage across its leads increases. This helps to prevent overload and current overshoot. Symmetrical impedance is a special circuit mode where the total resistance across the resistor is equal to the sum of both its resistance and capacitance components. This helps to limit the current passing through the resistor and also prevent overshoot.

Conclusion

The FMP100FRF52-549R is an important through hole resistor, used in a variety of applications to protect against overloads, clamping/limiting voltage overshoot, and circuit isolation. Its primary mode of operation is ohmic resistance and other modes include nonlinear resistance and symmetrical impedance. With its ability to handle high currents and its reliable performance, this resistors series is sure to be an important part of many circuits.
