Through Hole Resistors, such as the FMF200FRF73-30R, serve an important purpose in electrical and electronic systems. Through Hole resistors are the most basic type of resistors; they help to create a specific resistance rating that can effectively limit the current in the circuit. With the advent of surface-mount technology, through-hole devices (THD) have become less popular as they are seen as a waste of PCB space, but they are still widely beneficial in areas where the effect of vibration must be carefully controlled. In this article, we will first discuss the application field of the FMF200FRF73-30R before looking at its working principle.

Application Field

The FMF200FRF73-30R is a Through Hole Resistor used in a wide range of applications such as the electrical installation industry and automotive sectors. It is ideal for circuits with moderate to high power requirements, such as those found in electric motors, appliances, entertainment systems, and even aircraft. It is also suitable for applications in which the temperature changes dramatically and for situations where vibration might be a factor. Furthermore, it works well in inductive system applications like those found in UPS (uninterruptible power supply) systems, welding circuits, and high-efficiency motor circuits.

Working Principle

Through Hole Resistors like the FMF200FRF73-30R depend upon the mixed conduction mechanism for creating resistance in a circuit. The resistor consists of a pair of electrodes connected by a resistor element. When current passes through the electrodes, a resistive voltage drop is generated due to the varying resistive materials used in the resistor element. This voltage drop is a function of the material resistivity, resistor element length, and the current that is passing through the resistor.

The FMF200FRF73-30R has an operating temperature of -40°C to + 120°C. The resistance range is from 10 ohms to 1M ohm. The rated power, the maximum allowable power that is dissipated through the resistor, is 1/2W. The resistor has an electrodeposited flame retardant coating and moisture-resistant alloys which are suitable for operation with different kinds of chemicals. The construction of the resistor ensures excellent heat dissipation and high-temperature stability.

The FMF200FRF73-30R features excellent noise immunity and reliability. Its non-inductive design makes it ideal for applications where EMI (electromagnetic interference) is a major problem. The high-precision construction ensures a very small tolerance range, allowing for accurate measurement results. Finally, the high-grade materials used in its construction make it highly resistant to corrosion and other environmental factors.

Conclusion

Through hole resistors like the FMF200FRF73-30R offer a range of benefits in the field of electrical and electronics. It has proven to be highly reliable in a variety of applications, and its non-inductive design offers excellent noise immunity and exceptional temperature stability. Moreover, its high-grade construction ensures precise measurement results and reliable performance in a wide range of operating conditions. All these features make the FMF200FRF73-30R a great choice for a range of applications in the electrical and electronics industries.
