Through hole resistors, such like the H839R2BCA type, are a common type of resistor, found in a variety of applications within the electrical engineering industry. The particular type H839R2BCA is a precision resistor, meaning that its resistance value is extremely accurate and highly stable over both time, and a range of environmental conditionals. Broadly, the typical applications for the H839R2BCA type resistors are in AC and DC circuits which require precise resistance values. Additionally, H839R2BCA resistors are very attractive for functional testing and calibrating applications.

The working principle of a resistor, particularly for the H839R2BCA type, is relatively simple: A resistive element is connected in series with the electrical current, resulting in a decrease in current flow due to the creation of opposition. In the case of the H839R2BCA type, the resistance element comprises very thin alloy layers that are deposited onto a resonator. This gives the H839R2BCA its incredible resistance accuracy.

H839R2BCA resistors are commonly employed with AC and DC circuits, with the latter being the most prevalent. This is because the accuracy requirements for DC circuits tend to be vastly more stringent. For instance, the circuit must have stable voltage and current ratings, providing precise voltage and current values for circuits without stepping process. Furthermore, there are very stringent requirements on the level of temperature coefficient found in the resistor, something that the H839R2BCA is fully capable of. The reason for this is because a Precision film resistor, such as the H839R2BCA, is not susceptive to thermal drift, meaning the electrical resistance remains incredibly stable over large temperature ranges.

Beyond the DC circuits, the H839R2BCA is commonly used in a variety of AC applications such as load balancing, over-current protection, under-current protection, and AC capacitor control. In each of these scenarios, the requirement are for a very precise resistance value, stable over time and over a range of environmental conditionals.

The H839R2BCA can also be employed within the process of functional testing and calibration. This is a process in which the accuracy of products is tested and certified, without the need for destructive tests. In these processes, the H839R2BCA resistors are employed between two contacts in order to measure the current that flows between them. This helps to ensure that the products on test are certified, without causing any damage.

Overall, the H839R2BCA resistor is a highly accurate and stable precision resistor, with an operating principle that is simple yet efficient. Its highly consistent electrical resistance and low strain make it perfect for use in both AC and DC circuitry, while its inherent accuracy makes it ideal for use in functional testing and calibration applications. The end result is a versatile resistor that has a wide range of applications in the electrical engineering industry.
