In this article, we will discuss the application field and working principle of the AF164-FR-0790R9L, as well as how it fits into the larger category of resistor arrays.

Application Field

The AF164-FR-0790R9L is a flexible solution for a variety of applications. It is most commonly used in industrial and medical electronics due to its small size and customizable resistance values. It can also be used in sensor and radio frequency (RF) applications due to its low inductance and wide resistance range. Additionally, the AF164-FR-0790R9L is suitable for use in automotive and aerospace applications due to its long service life and temperature range.

Working Principle

The AF164-FR-0790R9L resistor network array is composed of nine resistors in a particular arrangement. This arrangement is designed to allow the user to customize their resistance value to fit their specific needs. The device consists of two types of resistors - two variable resistors and seven fixed resistors. The variable resistors are used to control the resistance value of the array, while the fixed resistors are used to provide stability and reduce noise.The variable resistors are connected in a 2-pole/3-pole configuration. This allows the user to adjust the resistance value by moving the poles of the resistors relative to each other. The fixed resistors are connected in a parallel configuration, which ensures that the total resistance value stays consistent throughout the whole network. This is especially important in applications where the resistance value must remain constant over time.

Conclusion

The AF164-FR-0790R9L resistor network array is a flexible and reliable solution in many different applications. Its small size and adjustable resistance values make it suitable for use in industrial and medical electronics, sensor and RF applications, and automotive and aerospace applications. The device consists of two variable resistors and seven fixed resistors which allow user to customize their resistance values and maintain consistent performance over time. This device is a part of the larger resistor array category, and as such provides a reliable solution for any design where resisters are necessary.
