Through Hole Resistors: 40FR75 Application Field and Working Principle

Through hole resistors are among the most widely used type of resistor in the electronics industry. They are available in a range of sizes and shapes, and are commonly used in printed circuit boards, prototype projects, and even in large-scale production. The 40FR75 is an industrial grade through hole resistor with a resistance range of 0.05Ω to 5.5KΩ.

The 40FR75 through hole resistor is a high-performance industrial device, capable of withstanding temperatures up to 125°C. It is designed to provide high-precision resistive elements, with tolerance levels of just 0.04%. It has excellent long-term stability, low noise characteristics, and low temperature coefficient of resistance, making it an ideal choice for a variety of industrial applications.

The 40FR75 through hole resistor is manufactured using a glass-filled epoxy substrate, which has a higher breakdown voltage than other types of resistor materials. This ensures that it is able to operate reliably in high temperatures, without compromising its reliability or accuracy. Additionally, the epoxy substrate material ensures that the 40FR75 is resistant to a wide range of chemicals, as well as having good electrical insulation properties.

The 40FR75 through hole resistor is designed with a square or rectangular core, which is insulated from the outside environment by its epoxy substrate. The core has a circuit pattern etched onto it, and the resistive element is then coated in the epoxy material. The 40FR75 can be supplied with either an exposed or bolted output terminals, depending on the user’s application.

The working principle of the 40FR75 through hole resistor is straightforward. When a current is passed through the resistor, electrical energy is converted into heat, which is then dissipated into the surrounding environment. The resistance of the device is determined by the amount of current passing through it, as well as the thickness of its epoxy substrate.

The 40FR75 is an ideal choice for many industrial applications, such as waveform generators, high-precision measurement systems, signal amplifiers, and high-frequency pulse amplifiers. It is also commonly used in automotive and military applications, due to its reliable performance and long-term stability. In addition, its sealed construction ensures that it is resistant to dirt, dust, humidity, and other environmental hazards.

In summary, the 40FR75 through hole resistor is an ideal device for industrial applications. It has a wide range of applications, and is designed to operate reliably under high temperatures. Its epoxy substrate material ensures that it is resistant to a wide range of chemicals and environmental contaminants. Additionally, its sealed construction helps to protect it against dust, humidity, and other environmental hazards. The 40FR75 through hole resistor is highly reliable and accurate, making it an ideal choice for industrial applications.
