Resistor Networks, Arrays are a type of passive component widely applied in various occasions. One of the popular varieties of Resistor Networks is 4612X-102-151LF, mainly used in circuit networks or PCBs. This article will discuss about its applications and working principle.

4612X-102-151LF Application

4612X-102-151LF is a resistor array with a total of 12 pins, and its size is 4.5mm by 3.3mm. The unique capability of this component lies in its 2 distinct functions. Its 8 off pins are connected in a 2X 4 array, allowing them to act as 4 resistor dividers while the other 4 pins help adjust the network resistance with its programmable pins. This feature is especially useful in applications where linearity and accuracy need to be guaranteed.

Moreover, 4612X-102-151LF is widely used in speech and audio systems. It is capable of fulfilling the voltage division requirements of speech and audio synthesizer features such as echoing, reverberation, sound balance, and more. Additionally, the adjustable pins in this component also offer great versatility. An example provided is a volume knob which can be applied to multiple sound sources. The adjustable pins can be utilized to adjust the resistance of the resistor array, allowing users to adjust the sound level of each sound source.

Working Principle

As mentioned above, 4612X-102-151LF is mainly composed of four resistors connected in a 2X4 array. One distinct feature of this component is that each of the four resistors can act as a series resistor, or a shunt resistor. The resistor array is divided into two branches, and the 4 adjustable pins are connected with each branch, to balance the resistance between them. This allows the number restrictions between the two branches to be adjusted according to the desired voltage ratio.

In addition, each of the 4 adjustable pins offers versatility. By applying a series of commands, such as setting a certain resistance, users are able to customize the network resistance to an ideal level for various scenarios. For instance, when a loudspeaker is connected across the resistor array, the adjustable pins can be used to adjust the ratio between the loudspeaker’s wattage and the wattage of the connected sound source.

To sum up, 4612X-102-151LF is a Resistor Network which provides users with great flexibility and suitability. It is mainly used in speech and audio systems, providing linearity and accuracy. Additionally, the 4 adjustable pins are also utilized to control the network resistance according to the desired ratio. In this way, the component is capable to offer great sound balance and sound level control.
