Resistor Networks, Arrays have long been used in various forms to provide stability in electronic circuits, control distortion and provide signal conditioning. The AF164-FR-07953RL application field and working principle is an example of this technology. In the case of the AF164-FR-07953RL, the application is as a low pass filter to reduce distortion in a signal coming from a microphone.

A low pass filter is used to reduce or attenuate the higher frequency components of a signal while allowing the lower frequencies to pass through. This is achieved with circuit components such as resistors and capacitors. In the case of the AF164-FR-07953RL, it uses a combination of network resistors and capacitors to provide this signal filtering.

The AF164-FR-07953RL is a four-resistor network with three of the resistors connected in series and one resistor connected in parallel. The four resistors that comprise the network are designated R1, R2, R3 and R4 and each one has a different resistance value ranging from 4.7 kilohms to 10 kilohms. The combinations of these different values are used to create the desired filter level.

The capacitors used in the AF164-FR-07953RL consist of four 0.1 microfarad (0.1µF) miniature capacitors. These capacitors form the low pass filter portion of the circuit. Each of the capacitors is connected in parallel with the corresponding resistor in the series combination of the three resistors connected in series.

The working principle of the AF164-FR-07953RL is based on the frequency-dependent impedance of each resistor in the series combination. The higher frequency signals will be blocked or attenuated by the resistors due to their higher frequency-dependent impedance. At the same time, the lower frequency signals will have a lower impedance and as a result, will pass through the network. This provides the desired low pass filter function.

The AF164-FR-07953RL is used in applications such as noise cancellation in microphones and audio systems. Its low pass filter characteristics reduce high frequency noise and other undesirable signal interference, allowing clean, undistorted signals to be heard.

The AF164-FR-07953RL is a great example of how a simple resistor network and array can be used to filter signals and provide stability in applications. As more and more devices are connected wirelessly, line conditioning and signal filtering will become even more important. Resistor networks and arrays are one of the best ways to achieve this filtering and will continue to be used for many years to come.
