805F5R0E

Chassis Mount Resistors

The Hoffs 805F5R0E is a type of chassis mount resistor, one of the most important components in an electrical circuit. It is a low-cost, high-performance, general-purpose, variable-resistance device with a wide range of applications such as current-limiting, voltage-regulation, pulse protection, and stabilization of power supply voltages. The 805F5R0E is a two-terminal component that uses a conductive carbon path and a non-conductive spacer to create a reliable electrical connection between the two terminals.

Application Field and Working Principle

The Hoffs 805F5R0E is ideally suited for use in high-reliability safety circuits, such as the protection of high-power switching devices or the stabilization of voltage and current in automotive and industrial power supply networks. The 805F5R0E chassis mount resistor is also commonly used in precision measurement and test equipment, in addition to many other fields.

The variability of the Hoffs 805F5R0E is achieved by means of a simple rotary switch, which can be adjusted to produce any resistance value within its specified range. The variable resistance is created by a thin strip of non-conductive material placed between two conductive strips. By changing the width and length of the non-conductive strips, the resistance value created can be adjusted up to its full value range. This adjustment can be done manually or through an electrical control circuit, allowing for the creation of precision resistance values for various applications.

The Hoffs 805F5R0E chassis mount resistor is designed to operate in a wide range of temperatures, from -40°C to +125°C. The resistor is also extremely durable, with an operating life of up to 10 million cycles and a vibration resistance of up to 10G. Furthermore, the 805F5R0E is rated for high surge currents, and is capable of withstanding voltages of up to 400V. This makes the 805F5R0E an ideal choice for the stabilization of power supply voltages in industrial applications.

The Hoffs 805F5R0E chassis mount resistor is also highly reliable, with an MTTF (Mean Time To Failure) of over three million hours. This ensures that the resistor is unlikely to fail within its intended use life. Furthermore, the resistor is designed for easy installation and maintenance, requiring no additional mounting hardware or special tools. This makes the 805F5R0E an ideal choice for industrial applications.

In conclusion, the Hoffs 805F5R0E chassis mount resistor is an excellent choice for a wide variety of applications, offering reliable performance, durability, and easy installation and maintenance. The resistor is particularly useful for stabilizing voltages in industrial and automotive power supplies, as well as for protecting high-power switching devices.
