Introduction

Through hole resistors, also known as throughhole resistors or as leaded resistors, are resistors that are specifically designed to be soldered onto a printed circuit board (PCB) from the top side, hence the name through hole resistors. Although the popularity of surface mounted resistors has risen substantially in recent years, through hole resistors are still an important component in many electronics applications. In this article we will take a look at one of the more popular through hole resistor types - the FMP100FBE52-309R. We will discuss the purpose of this component and its applications, as well as its working principle and construction.

The FMP100FBE52-309R Through Hole Resistor

The FMP100FBE52-309R is a surface-mountable through hole resistor that has a resistance value of 100 ohms. It is manufactured by the American-based firm F&S Electronics and is a 10 watt resistor with a tolerance of ±10%. It features a wide diameter and a heavy construction that make it ideal for higher power applications and provides exceptional heat dissipation, as well as a moisture rating of 70C/85%. The FMP100FBE52-309R is also an ideal choice for high frequency applications, as it has a frequency rating of 1 MHz. It has a power rating of 10 watts and a dissipation of 10 watts, which makes it suitable for a variety of applications that require a high power rating.

Applications of the FMP100FBE52-309R

The FMP100FBE52-309R through hole resistor is used in a variety of applications, most notably in power supplies, electronic circuits, and communication systems. In power supplies, it is used to regulate the current flow and prevent the risk of overvoltage and overcurrent. In communication systems, it is used to dampen the voltage waveforms and reduce signal distortion. It can also be used in electronic circuits, such as in radio transceivers, to provide impedance matching and voltage protection. In addition, it can be used as a current limiter in flyback or buck-boost converters.

Working Principle of the FMP100FBE52-309R

The FMP100FBE52-309R through hole resistor works on the principle of Ohm\'s law, which states that the current (I) passing through a resistive element is directly proportional to the applied voltage (V) and inversely proportional to the resistance (R). In other words, the current flowing through the resistor is equal to the voltage applied divided by the resistance value, I = V/R. The FMP100FBE52-309R through hole resistor is manufactured to meet the requirements of Ohm\'s law, as it has a resistance value of 100 ohms, and can withstand a maximum voltage of 10 watts. This makes it ideal for applications that require a large voltage or current rating.

Construction of the FMP100FBE52-309R

The FMP100FBE52-309R through hole resistor is constructed using a metal-film technology. This technology eliminates the need for a ceramic substrate, and instead uses a metal layer that is sputtered onto a substrate. The metal layer is then oxidized before being enclosed in a flame retardant casing. The resistor is designed with a wide body that ensures a large dissipation factor, and also includes plated terminals that make it easier to solder onto a PCB. The resistance value of the resistor is marked on the top, and also includes a tolerance rating of ±10%.

Conclusion

The FMP100FBE52-309R through hole resistor is an excellent choice for high power applications, as it is able to withstand a maximum voltage of 10 watts. It is a popular choice in power supplies, communication systems, and for other applications where impedance matching and voltage protection are needed. It is constructed using a metal-film technology that ensures a large dissipation factor, and also includes plated terminals that make it easy to solder onto a printed circuit board. Its wide body ensures a large dissipation factor and its tolerance rating of ±10% makes it ideal for applications that require a precise resistance value.
