Introduction to Through Hole Resistors

Through hole resistors is a general term for resistors that come in the form of discrete components, which require a hole be drilled into a PCB to be mechanically and electrically held in place for proper operation. This construction type is increasingly becoming obsolete in favor of surface mounted technology (SMT), but it still has its place in modern electronics. The MFR100FRF73-182R is one such through hole resistor, a metal film resistor with a rated power of 1 Watt.

Application Field

Through hole resistors are used in a wide variety of applications, ranging from circuit protection to fixed load balancing. They can be used in high power applications, where the power resistors dissipate the excess energy as heat. Through hole resistors are also used as current limiters in power units, and for clipping high voltage signals. Because of the robust physical construction of the MFR100FRF73-182R, it has a wide application field in the automotive, audio and power circuits in which it can be used.

Working Principle

At the heart of any resistor is the resistor element, which is responsible for restricting the flow of current. The material which makes up the resistor element can vary between ceramic, carbon, film, and many others. The MFR100FRF73-182R uses a metal film resistor element which restricts the flow of current by creating electrical resistance. This resistance is often expressed in Ohms, with the MFR100FRF73-182R boasting a resistance of 1 Ohm.The MFR100FRF73-182R is a through hole resistor, meaning that the components need to be drilled into the PCB for mechanical and electrical stability. When the resistor is soldered to the PCB, the electrical connection between the component and board is complete. This means that the resistor can now act to restrict the flow of current as specified by its design.

Conclusion

Through hole resistors such as the MFR100FRF73-182R are still a common sight in modern electronics. They are used for a wide variety of applications, but their main purpose is the same: To restrict current flow. They are made up of a resistor element which restricts the flow of current by creating electrical resistance, and can be soldered to the board in order to maintain a stable connection. Through hole resistors are slowly being phased out in favor of Surface Mount Technology, but they still have their place in today\'s electronics.
