Through Hole Resistors play a pivotal role in a variety of electronic circuits and typically are engineered to be lightweight and compact. FMP100FTF52-107R is a common type of through hole resistor. This application is outlined below, together with a discussion of its working principle.

Application Field

FMP 100FTF52-107R is a four-terminal metal resistance film resistor. Its main electrical characteristics are power rating, temperature coefficient, voltage coefficient, Humidity sensitivity coefficient, and maximum working voltage. It is mainly used in some electronic circuits which require high accuracy, long life and stable performance.

This resistance film resistor is oftentimes utilized in measuring equipment such as transducers, shunt batteries and normal circuitry, it can also be used in muti-channels /high performance amplifiers, AC or DC power supplies and power switch equipment. Because of its superior resistance accuracy and temperature stability, the FMP100FTF52-107R is particularly well suited for precision and highly reliable equipment.

Working Principle

The FMP100FTF52-107R is a ceramic insulator resistor with an metal deposited resistance film as the active element. This is incorporated into a compact design, in which two terminal metal outputs are mounted within a series of internal metal frames, eliminating potential loosening and openings.

When a current passes through the resistor, more power is generated from a specific area, resulting in a temperature increase. As temperature rises above the desired operating temperature, the intrinsic resistance will increase, resulting in a decrease in current. This process is known as self-heating, and it\'s an important factor in maintaining the stability of the FMP100FTF52-107R.

The metal film (which is an alloy of Nickel Chromium) will also undergo a process called thermal diffusion. This occurs when the resistance film is heated by a current, resulting in a redistribution of particles within the resistive medium. The observed thermal coefficient of resistance is usually around 25 ppm/°C between 25°C and 100°C. As temperature rises, the resistance of the FMP100FTF52-107R increases in order to maintain the accuracy of the equipment.

In addition, the resistor is designed to be an outstanding choice for applications where power dissipation needs to be kept to a minimum. This results from its precision construction and the small size of the resistive layer, making it much less prone to dissipate heat. In turn, this can support many types of electronic circuits which require high capacity without producing too much heat.

Moreover, the FMP100FTF52-107R has a precision interlock structure, one of its key features. This maximizes its reliability and stability during the assembly and operation process. The resistor is also engineered with an epoxy coating that provides excellent environmental protection and makes it fit for long-term use. Overall, FMP100FTF52-107R is a highly efficient and reliable device for a wide range of through hole applications.
