Chassis Mount Resistor: 810F75RE Application Field and Working Principle

Chassis mount resistors, such as the 810F75RE, are commonly used in electronic equipment in order to maintain a stable current flow in order to protect components and cables. The 810F75RE is an axial leaded, medium power, fixed-value chassis-mount, through-hole resistor, which provides medium to high-surge current capability at high ripple frequencies, in a small, surface-mountable package. Its high power rating makes it ideal for use in power-control circuits and voltage regulation.

Working Principle

The working principle of the 810F75RE chassis mount resistor revolves around the concept of Ohm’s law, a law which states that the current (I) through a resistor is equal to the voltage (V) applied divided by the resistance (R) of the resistor.

I = V/R

In practical terms, the 810F75RE functions by limiting the current, or flow, of electricity from the power source to the component or circuit which it is protecting. The resistor acts as an impedance, preventing too much current from passing through the circuit. The 810F75RE’s resistance is determined by its resistance value, which is listed in the documentation.

For instance, a device or circuit which is rated for 12V and requires 1A of current to function will need a 810F75RE resistor with a resistance of 12 ohms to ensure that the correct amount of current passes through it. In this case, the equation will be the following:

I = 12V / 12 ohms = 1A

Application

Due to its high power rating and small size, the 810F75RE is most commonly used in automotive, industrial and consumer applications. It is commonly used as an overload protector for circuits in these scenarios. Chassis mount resistors are also used in other fields where an overload or overcurrent event may be possible. For example, it can be used as a temperature protector for electric motors, as it will regulate the current needed to spin the motor, ensuring that it does not overheat.

In terms of automotive applications, the 810F75RE resistor can be found in a variety of different applications, from controlling the current flow for headlights to regulating the current level for speedometers and other warning lights. Additionally, it can be used to regulate the current for audio systems, where it helps control the current for the speakers and amplifier.

In consumer settings, chassis mount resistors are often used in power supplies for a variety of applications, many of which involve audio equipment. These resistors are used in sound systems to regulate the current flow and protect against overloads, as well as in stereo systems in order to regulate the current to the speakers and other components.

Conclusion

In summary, the 810F75RE chassis mount resistor is an axial leaded, medium power, fixed-value chassis-mount, through-hole resistor which provides medium to high-surge current capability at high ripple frequencies, in a small, surface-mountable package. It is commonly used in automotive, industrial and consumer applications as an overload protector, and is most commonly used in audio systems and power supplies. By regulating the current, it helps protect components and cables from overloads or overcurrent events.
