FMP100FRF52-143R

Through hole resistors are one of the most widely used and practical electrical components available. FMP100FRF52-143R is one of the most common through hole resistors and it is in many applications. This article will discuss its application field and working principle.

Application Field

The FMP100FRF52-143R is a power resistor which is typically used in the power line voltage regulator circuit, such as in AC motor control, electronic voltage regulator, circuit breaker (circuit breaker), DC power indicator, etc. It can also be used as a load resistor for motors, lighting circuits, and other overload protection circuits. In addition, it is also often used in process control circuit in which accurate voltage regulation is desired.

Working Principle

The FMP100FRF52-143R is a fixed value non-inductive wirewound resistor, and the working principle mainly lies in its physical properties. Firstly, due to its the large resistance value provided by its fixed length of winding wire, the current which is passed through it must be divided into many smaller increments for it to allow current to flow through. Therefore, its resistance and power determination will depend on the length and material of the winding wire.

Its resistance value also depends on the operating temperature. At room temperature, the FMP100FRF52-143R offers a stable resistance value at 50 ohms. However, when the operating temperature rises, the resistance value decreases. It is because of this characteristic that it is used in applications which require heat dissipation and thermal protection. Moreover, the current protection of the resistor is also related to its ability to dissipate heat. The higher the wattage of the resistor, the better its resistance value and heat dissipation.

In summary, the FMP100FRF52-143R is a versatile through hole resistor that is used in different application fields. Its resistance depends on its physical properties, such as winding wire length, material and wattage. It is also suitable for operating in high temperature environments for its ability to dissipate heat. The FMP100FRF52-143R is a reliable and cost-effective resistor with various applications.
