Resistor Networks, Arrays

The EXB-24V621JX is a two-terminal (two-lead) device which is widely used in various fields such as telecommunications, industrial control, instrumentation, and consumer applications. This resistor network array has been designed specifically to provide high precision, low noise and excellent reliability.

Construction

The EXB-24V621JX consists of a substrate material that is composed of multiple layers. The topmost layer of the substrate contains the wiring that forms the two-terminals of the resistor network. A permanently attached capacitor is also located on top of the substrate. This capacitorserves to reduce circuit noise, as well as creates a low frequency performance characteristic due to its low oxide dielectric.

Array of Resistors

Beneath the capacitor lies a thin film of resistive material that is screen printed onto the substrate. This resistor material is composed of peroxides, carbon, alumina, and other materials that are alloyed together to achieve desired characteristics, such as low noise and high precision.The actual resistors are located below the thin film of resistive material. This layer of the substrate contains an array of resistors that are spaced across the substrate. Each resistor has a predefined value that is laser trimmed for optimum performance of the device and is marked with a binary code.

Applications

The EXB-24V621JX is well suited for applications that require precision, accuracy, and repeatability, such as: instrumentation, data acquisition, telecommunications, industrial control, motor control, and consumer applications. It is often used to provide precise input voltage signals for circuits such as high gain amplifiers, filters, and pulse stretchers.

Working Principle

The EXB-24V621JX operates by the principle of voltage division. When a voltage is applied across the two terminals of the device, that voltage is divided among the various resistors that are included in the array. The voltage set at each resistor is determined by the size of that resistor. This causes a proportional voltage difference between each resistor. The total voltage applied to the device is divided among all of the resistors. By carefully controlling the values of each resistor, a precisely tailored voltage divider can be achieved.

Conclusion

The EXB-24V621JX is a two-Terminal resistor network array that is designed for precision and reliability. It is comprised of a substrate material with a thin film of resistive material and an array of resistors that have been laser trimmed and marked with a binary code. The resistor network operates by the principle of voltage division, providing a tailored voltage divider for applications such as instrumentation, telecommunications, and industrial control. With its low noise, high precision, and excellent reliability, the EXB-24V621JX is an ideal choice for any need that requires precision and accuracy.
