Through Hole Resistors are widely used in a variety of fields, from electronic power systems to medical electronic devices, from signal processing to circuit implementation. FMP300FRF73-422K is one of the most popular type of Through Hole Resistors available today. In this article, we will focus on the application field and working principle of FMP300FRF73-422K.

Application Field: FMP300FRF73-422K is mainly used in low voltage electronic equipment and is capable of withstanding high temperatures up to 200°C. It is suitable for applications such as temperature control relays, frequency-controlled electric motors, and pulse transmission networks. In addition, FMP300FRF73-422K is also applicable to power supplies in electronic equipment, power monitoring electronics, and flow control circuitries such as micro-valves.

Working Principle: FMP300FRF73-422K is a carbon composition-type Through Hole Resistor. It is comprised of a resistor body, terminals, and a non-magnetic core. Resistor bodies are usually made of porcelain, alumina, ceramic, zirconia, or mica for superior insulation. The terminals are usually copper or other metals to ensure good conductivity. The resistor body is then surrounded by a nonmagnetic core material that works to limit the heat produced by the resistor body.

The FMP300FRF73-422K works by allowing current to flow through the resistor body and terminals, creating heat. The non-magnetic core works to reduce the heat produced, however some heat will still be produced. This heat is then dissipated into the surrounding environment. This process effectively reduces the amount of current that can flow through the resistor, ultimately resulting in a desired resistance value.

In conclusion, FMP300FRF73-422K is a high temperature, Through Hole Resistor that is mainly used in low voltage electronic equipment. It consists of a resistor body, terminals, and a non-magnetic core, which work together to limit the heat produced by the resistor and dissipate it into the surrounding environment. This results in a reduced current flow and a desired resistance value. As such, FMP300FRF73-422K is a highly versatile and reliable Through Hole Resistor.
