4820P-T01-152

Resistor networks, arrays, and the 4820P-T01-152 offer many opportunities for use in the field of engineering. They are a versatile, reliable, and powerful tool used in a wide range of applications.

What Is a Resistor Network?

A resistor network is a discrete device consisting of three or more resistors that are interconnected in a circuit to control electrical current or to provide calibration values. Their design makes them great for regulating current and providing reference voltages, especially for signal and power amplifiers, as well as providing buffering. Resistor networks may also be connected in a parallel or cascaded fashion, to increase stability, reduce system noise, or to provide a series of voltage dependent variables.

What Is an Array?

An array is a set of electrical devices such as resistors, capacitors, and/or inductors connected in a specific arrangement. Array structures can be used to arrange components in a certain order or to build channels, filter frequencies, or simulate natural phenomena. Arrays are also very useful for dividing a signal into several, separate independent elements.

What Is the 4820P-T01-152?

The 4820P-T01-152 is a type of resistor network that is designed for use in telecom and data acquisition equipment. It is a two- and four-layer network with SMT (Surface Mount Technology) resistors that can be tailored for specific applications. It offers two ground layers that are connected together to provide superior stability and low EMI (electromagnetic interference) susceptibility. It also features a solid polyimide base which offers excellent performance in high temperature applications. Additionally, the 4820P-T01-152 provides excellent flexibility in the design of channels, filtering, and signal stabilization.

Applications

The 4820P-T01-152 is a versatile device that can be used in a variety of applications. It has proven to be a great solution for high temperature communications applications such as military and aerospace, telecom and data acquisition, medical imaging, and embedded control. Additionally, this product is suitable for use in signal processing, channelizing, and switchbox applications. It also stands out as an ideal solution for applications that require shielding and where use of internal components has to be minimized.

Working Principle

The 4820P-T01-152 is a two-layer network with SMT resistors, a solid polyimide base, and two ground layers. It operates on a simple principle: when current flows one direction through one layer, it creates a voltage drop which is proportional to the number of resistors in the layer. If the current is reversed, the voltage dropped across the resistors is no longer a 1:1 proportion to the resistors in the layer but rather is determined by the difference between the resistors. This allows for precise adjustments in the performance of the device.

Furthermore, since the resistors are connected in a two-layer configuration, each layer can receive different voltages or currents, allowing for greater flexibility in adjusting performance or creating channels. This two-layer network is shielded by the two layers of grounding, thus providing superior noise interfering and EMI protection.

Conclusion

The 4820P-T01-152 is an extremely versatile device which offers many advantages over other types of resistor networks, arrays, and other components. It operates on a simple yet reliable principle and offers superior shielding, stability, and flexibility. This type of network is an ideal solution for applications such as medical imaging, communication, data acquisition, and embedded control.
