Chassis Mount Resistors are electrical components that are used to introduce a specific amount of resistance into a circuit, increasing or decreasing the magnitude of the current. The 805F20KE is a resistor that falls within the chassis mount resistor category, and offers a great deal of functionality in specific applications. In order to understand the applications and working principle of the 805F20KE, it is important to look first at the details of the component itself.

The 805F20KE is a 1/4 watt resistor that is constructed from a ceramic body and a metal end cap. It has a voltage rating of 300V and a maximum temperature rating of 315 degrees Celsius. The 805F20KE is also electronically marked for identification and stability, meaning it can be used without worry in applications containing sensitive electronic circuitry. It is a low resistance resistor, with maximum resistance rating of 2.2 ohms. This makes it a great choice for applications that have limited space available and that require a smaller, lower resistance resistor in order to function correctly.

The primary application for the 805F20KE is in low voltage applications. It is suited for applications where a lower power level is necessary, such as in power supplies, audio amplifiers, and signal conditioning circuits. It is also great for use in telecommunications equipment, test and measuring equipment, as well as industrial controls. The 805F20KE is also ideal for circuit protection (by limiting current flows) and for providing filtering services. In each of these applications, the 805F20KE can be used in order to provide an adjustable resistance that is tailored to the needs of the specific application.

The working principle of the 805F20KE is quite simple. When a voltage is applied across the ends of the resistor, a proportional amount of current will flow through the resistor. The resistance of the 805F20KE is set when it is manufactured, and it can provide the same amount of resistance regardless of the magnitude of the applied voltage. This resistance will limit the amount of current that is allowed to flow through the resistor, and it will remain constant until the power passing through it exceeds its maximum ratings. The 805F20KE is designed to dissipate the excess power, ensuring that there is no overload of the resistor.

In conclusion, the 805F20KE is a type of Chassis Mount Resistor that is specifically designed for low voltage applications. It is constructed from a ceramic body with an electronically marked metal end cap, and is capable of providing a maximum resistance rating of 2.2 ohms. It is commonly used in power supplies, audio amplifiers, and signal conditioning circuits, as well as many other low voltage applications. The 805F20KE operates on a simple working principle that allows a constant resistance to be maintained regardless of the magnitude of the applied voltage, while also limiting the amount of current that is allowed to pass through the resistor.
