Resistor Networks, Arrays are commonly used in electronic circuits as connection, division and instrumentation devices to connect or divide circuits for signal processing. Among these devices, SF002B14K5/75KFB is one type of Resistor Networks, Arrays, which is especially suitable for impedance-matching applications. So, in this article, we just introduce its application field and working principle.

SF002B14K5/75KFB, a 14-position terminal resistor array, is typically used in audio path for impedance adjustment, which is avoid extra amplification of noise and improve the S/N. In addition, both of its impedance and its equivalent series resistance (ESR) are low, and it will be suitable for high-frequency systems requiring high impedance and low loss. All of these features provided by this resistor array make it to be used in some key projects.

Specifically, this resistor array can be used in cellular phones, DVD, auto sound system and other signal processing devices. Because it has small size, low series resistance and wide frequency bandwidth, it can effectively reduce crosstalk, equal gain amplitude and reduce group delay time, thereby improving the stability and accuracy of the system. Additionally, its ceramic substrate structure also makes it able to provide higher temperature range.

This resistor array consists of 14 series of terminals that can be connected in various combinations to modify the impedance of the system, mainly depending on the customer’s matching, noise control, equalization or sampling requirement. Here are some of its practical applications that we have seen in recent projects:

• Impedance Matching: In systems with a wide range of signal frequencies, an SF002B14K5/75KFB resistor array can be used to match impedances of incoming and outgoing signals, as the impedance value can be adjusted from 2K5 to 75K.
• Crosstalk: In any system, crosstalk is one of the main problems. The SF002B14K5/75KFB can minimize this crosstalk by providing an optimum impedance.
• Equal Gain Amplitude: SF002B14K5/75KFB is used to keep the gain of signals equal, regardless of their frequency.
• Group Delay Time: As the signal frequency is decreasing, the SF002B14K5/75KFB array can balance the delay time in order to reduce distortion and improve signal integrity.

To understand how the SF002B14K5/75KFB works, we’ll review the basic principle behind resistor arrays. A resistor array is a network of resistors, usually with some combination of resistance levels. In the SF002B14K5/75KFB, each resistance value is different. By controlling the connection of each resistor, we can adjust the impedance of the system.

Essentially, the SF002B14K5/75KFB resistor array works in the same way as a passive low-pass filter, in which the signal current divides between the resistors. Depending on the connection of the resistors, which can be changed depending on input requirements, the resistor array can be used for various tasks. For example, it can be used to equalize the resistance between high-frequency and low-frequency signals, as well as to reduce crosstalk between two signals.

In conclusion, the SF002B14K5/75KFB is a useful resistor array, with various application fields and working principles. Generally, it is mainly used in audio path for impedance adjustment, such as impedance matching, crosstalk reduction, equal gain amplitude, and group delay time adjustment, which are beneficial for signal quality.
