Resistor Networks, Arrays

Resistor networks, arrays, and other passive components are widely used in various electrical and electronic circuits. AF164-FR-0711K5L is a resistor array developed by AFI Technologies Inc. The device is a miniature four-resistor network whose characteristics make it ideal for active filter designs. In this article, we will discuss the application field and working principle of AF164-FR-0711K5L.

Application Field

The AF164-FR-0711K5L resistor array is designed for use in low-frequency active filter circuits. It is a miniature four-resistor network consisting of four individual resistors. Each resistor has an accuracy of 0.1% and an operating temperature range of -40°C to +125°C. The network is also capable of dissipating up to 1.25W, making it suitable for filter applications in most electrical and electronic systems.

This component is especially popular in automotive audio systems. Its low-profile design and tight tolerances make it an ideal solution for filters with low-frequency responses. Additionally, it can be used in communications systems, instrumentation systems, and other applications requiring high-precision control of filter performance.

Working Principle

The working principle of AF164-FR-0711K5L is based on a passive filter circuit. This type of circuit is typically used to remove unwanted signals from a signal source. The circuit consists of four resistors arranged in a specific combination that allows the desired signals to pass while attenuating the unwanted signals.

The AF164-FR-0711K5L resistor array is designed to reject unwanted signals up to 18 dB. This means that signals with frequencies higher than the cutoff frequency will be removed from the circuit, while signals with frequencies below the cutoff frequency will be allowed to pass. The cutoff frequency is determined by the arrangement of the four resistors, which must be adjusted to meet the specific requirements of the filter circuit.

In addition to the four resistors of the array, the AF164-FR-0711K5L includes two capacitors to further improve the filter performance. The capacitors are connected in series with the four resistors to form an LC network, which improves the frequency response of the overall filter circuit. Additionally, the LC network also reduces the amount of power consumed by the circuit, which increases efficiency.

Conclusion

The AF164-FR-0711K5L resistor array is an ideal solution for low-frequency active filter designs. The device is capable of rejecting unwanted signals up to 18 dB and offers a high degree of accuracy with 0.1% tolerance. Furthermore, the passive filter circuit also consumes less power compared to other solutions. All these features make AF164-FR-0711K5L an ideal solution for automotive audio systems and other applications requiring high-precision filter performance.
