Through Hole Resistors are an essential component of any electronic circuit. The 85F40R2 is a type of through hole resistor designed for applications where a reliable, compact and heat resistant resistor is needed. This article will discuss the application field and working principle of the 85F40R2.

Overview

The 85F40R2 is a through hole resistor designed to operate in the most extreme of environments. It can withstand temperatures ranging from -40°C to 125°C (-40°F to 257°F). It is also designed to be highly reliable, with a maximum operating current of 6 amps. It is a compact design, measuring just 7 mm in diameter.

Application Field

The 85F40R2 is primarily designed for use in automotive, medical and telecommunications applications. It is designed for extremely harsh environments, making it an ideal choice for use in these applications. The 85F40R2 is also suitable for use in appliances, where a reliable and heat-resistant resistor is required. It is also suitable for use in industrial applications, where reliable performance is required in a small space.

Working Principle

The 85F40R2 is a through hole resistor that works by providing a resistor in series with a signal path between two points. When a current passes through the resistor, it produces a voltage drop across the resistor. This voltage drop limits the amount of current that can flow through the circuit. As the voltage across the resistor increases, the resistance of the resistor increases, limiting the amount of current that can flow. This allows the 85F40R2 to be used to control the flow of current through a circuit.

The 85F40R2 is designed to dissipate heat from its components. The resistor is constructed with a copper base and a special dielectric layer between the components. This layer helps to reduce heat transfer from the resistor. The resistor also contains a special thermistor to protect the resistor from extreme temperatures. This thermistor helps to ensure that the resistor does not overheat and can withstand a wide range of temperatures.

Conclusion

The 85F40R2 is a through hole resistor designed for applications where reliable and heat resistant performance is required. It is ideal for use in automotive, medical and telecommunications applications as well as in industrial and appliance applications. The 85F40R2 works by providing a resistor in series with a signal path to limit the current that can flow. The resistor also contains a special thermistor to protect the resistor from extreme temperatures. This ensures that the resistor can withstand extreme temperatures and can be used reliably in a variety of applications.
