Through hole resistors are one of the most indispensable resistors available today. There is a wide range of through hole resistors applicable for various applications and working principles. The FMP 300JR-73-10K through hole resistor is an example of such a type of resistor. This article discusses the application field and working principle of the FMP300JR-73-10K.

The FMP300JR-73-10K is mainly used in industrial and automotive applications, as well as power supplies. It consists of a ceramic core, two metal plates, one end of which is connected to ground potential, and a metal or ceramic disk, which has a resistor element etched onto it. The resistance value of the FMP300JR-73-10K is 10KΩ and it has a power rating of 300 watts.

The FMP300JR-73-10K is designed to provide overload protection and current regulation for high-power applications. The device works by restricting the flow of electrons across the resistor, thus imposing a maximum current on the circuit. The resistance value of the resistor is adjusted by varying the thickness of the ceramic core, the diameter of the metal disk, or the size of the metal plates. The temperature coefficient of the resistor is also adjustable, so that the device can be used in high temperature applications.

The working principle of the FMP300JR-73-10K is simple. When the circuit is energized, the resistor has a certain resistance value and the current passing through it is determined by the voltage applied. As the current increases, the voltage drop across the resistor increases proportionally, and the resistance value of the resistor is decreased accordingly. This allows the device to provide current regulation in power supplies where the voltage drop varies with the amount of current.

The FMP300JR-73-10K also has a wide operating temperature range, making it ideal for industrial and automotive applications. It can operate in temperatures up to 150°C without degradation of performance. Additionally, its high power rating ensures that it can handle high current applications without risk of overheating or damage. In addition, the FMP300JR-73-10K is RoHS compliant, making it safe to use in any environment.

The FMP300JR-73-10K is a reliable and efficient resistor that is suitable for a wide range of high power applications. Its adjustable temperature coefficient and wide operating temperature range make it ideal for use in a variety of industrial and automotive settings. Thanks to its robust construction and precise resistor element, the FMP300JR-73-10K provides excellent current regulation, overload protection, and power stability. This makes it a reliable and cost-effective solution for high-power applications.
