Chassis Mount Resistors: 805F1R0E Application Field and Working Principle

Chassis mount resistors are used extensively to prevent short circuits in any electronic devices. They are widely available, easy to install, and relatively low cost. Typically, these resistors are used in audio/video equipment, computers, and telecommunications devices. The 805F1R0E chassis mount resistor is a non-inductive and non-magnetic style of resistor that is available in both rectangular and round packages, making it ideal for various applications.

Overview and Types

The 805F1R0E chassis mount resistor is an ideal choice for many applications. It offers low inductive values, high accuracy, low temperature coefficients, and high power performances. These resistors come in both vertical and horizontal mounting styles, so they can be used with great flexibility. The 805F1R0E chassis mount resistor also has multiple waveshape characteristics such as triangular, square wave, and harmonics up to 25dB. It is also available in various resistance values from 4 ohms up to 9K ohms.

In addition, the 805F1R0E chassis mount resistor is available in both wire-wound and metal-oxide-film varieties. The wire-wound type can provide a greater range of resistance values than the metal-oxide-film type. Wire-wound resistors provide superior noise suppression and temperature stability due to the fact that the resistive element of the resistor is wrapped around many strands of fine insulated wire. The metal-oxide-film type of chassis mount resistor also has a variety of resistance values, but they are more prone to drift with temperature variation.

Design

The basic design of an 805F1R0E chassis mount resistor consists of a metal body with a ceramic core. The metal body provides the electrical connections and acts as a heat sink to dissipate heat from the resistor. The ceramic core contains a resistive wire mesh that is typically wound around a spool of heat-resistant material. The spools are then slotted into the ceramic core and the resistive wire mesh is strung between the spools. This design ensures that the resistor can dissipate heat quickly and provides an even resistance throughout its entire resistance range.

Working Principle

The 805F1R0E chassis mount resistor works on the principle of Ohm\'s Law. Ohm\'s Law states that the voltage (V) applied across a resistance (R) will generate a current (I) through the resistor according to the equation: V = I x R. The resistive wire mesh acts as a resistor in the circuit, and the current generated through it is proportional to the voltage applied across it. When the correct resistance is selected, the current generated through the resistor will be equal to the voltage applied across it.

Applications

The 805F1R0E chassis mount resistor is used for a variety of different applications including: audio/video equipment, computers, telecommunications equipment, and automotive systems. It is ideal for high current and low voltage applications such as power supplies and DC motor controllers. It is also used for AC or DC voltage regulation, surge protection, and EMI/RFI filtering. The 805F1R0E is also used in high-frequency switching applications such as universal motor controllers and LED controllers.

Conclusion

The 805F1R0E chassis mount resistor is an incredibly versatile type of resistor, as it is available in both resistance values and different mounting styles. It is highly accurate and has very low temperature coefficients, making it ideal for many applications. It is also capable of producing multiple waveshape characteristics and dissipating heat quickly. As a result, the 805F1R0E chassis mount resistor is an excellent choice for a wide variety of electronics applications.
