Resistor Networks, Arrays

Resistor networks, or arrays, are composed of multiple resistors connected together in various configurations that can be used to create a voltage divider, filter, equalizer, multiplexer, or any number of other circuit functions. The AF164-FR-0721KL is one such resistor network. It consists of 4 resistors connected in a series configuration.Each resistor in the AF164-FR-0721KL can handle 1.2 Amps and is rated for 250 volts. The resistance of each individual resistor is 0.47 Ohms, but when connected in the series configuration of the AF164-FR-0721KL, the total resistance of the network is 1.88 Ohms. The network can be used to create a voltage divider that will divide the input voltage by a factor of 1.88.Another application of the AF164-FR-0721KL is a band pass filter. A band pass filter passes a certain frequency range in the input signal while blocking other frequencies. Because the AF164-FR-0721KL is composed of 4 resistors connected in series, it creates a resonant frequency filter when connected with a capacitor and an inductor. The capacitance and inductance of the capacitors and inductors used in this configuration determine the resonance frequency. This allows for the filtering out of certain frequencies in the input signal.The AF164-FR-0721KL can also be used as an equalizer. The AF164-FR-0721KL is connected to an amplifier and is used to modify the frequency response of the amplifier. By adjusting the resistors in the AF164-FR-0721KL, the frequency response of the amplifier can be adjusted. This allows for fine tuning of the amplifier’s sound characteristics.Finally, the AF164-FR-0721KL can be used as a multiplexer. A multiplexer is a device that can combine multiple signals into a single output. The AF164-FR-0721KL can be used in conjunction with logic gates and amplifiers to perform this function. The AF164-FR-0721KL has four inputs, allowing for multiple signals to be combined into a single output.The AF164-FR-0721KL is a versatile resistor network that can be used to create voltage dividers, filters, equalizers, and multiplexers. Each resistor has a rating of 1.2 Amps and is rated for 250 volts. The resistance of each individual resistor is 0.47 Ohms, but when connected in the series configuration of the AF164-FR-0721KL, the total resistance of the network is 1.88 Ohms. The AF164-FR-0721KL can be used in applications where a voltage divider, band pass filter, equalizer, or multiplexer is needed.
