Resistor Networks, Arrays

The 742C083181JP is a type of resistor network, which is sold as a complete package. It consists of a resistor array, which is defined as two or more resistors in close proximity, coupled with an insulation matrix. The resistor array is typically designed to offer similar electrical characteristics to a single resistor, but with lower resistance values and higher accuracy. They are used in applications that require a lower power dissipation than a single resistor, while maintaining high accuracy.

The 742C083181JP is designed for use in high reliability hybrid circuits such as automotive, military, medical and telecom products. It is designed to meet various industry temperature specifications, withstanding temperatures up to +85 degrees Celsius. It has an insulation resistance rating above 100 Mohm at 500V dc.

Working Principle

Resistor networks operate based on Ohm\'s law. When two resistors are connected in parallel, the overall resistance of the circuit is the sum of both resistors, divided by the sum of the inverse of both resistors. The resistance of each resistor is equal to the total resistance of the network multiplied by the fraction of that resistor relative to the total resistance. By connecting multiple resistors together, the overall resistance of the circuit can be reduced, resulting in a lower power dissipation.

The 742C083181JP has an array of resistors connected in parallel to form an array of resistors. The array of resistors is then connected to an insulation matrix. The insulation matrix helps to protect the array of resistors from external electrical noise and helps to maintain the resistances of the individual resistors in the array. The individual resistors in the array are designed to have similar electrical characteristics to a single resistor, while also having lower resistance values and higher accuracy.

Application Field

Resistor networks such as the 742C083181JP are used in a variety of applications. They are used in high-reliability hybrid circuit designs, such as automotive, military, medical and telecom products. They are designed to meet various industry temperature specifications, as well as provide for lower power dissipation and higher accuracy when compared to single resistors.

They are also used in applications that require precise voltage division circuits. By connecting two resistors in parallel, the overall resistance of the circuit can be reduced, resulting in a lower voltage drop. This allows for more accurate and consistent voltage division ratios.

Resistor networks are also used as current limiters. By connecting a resistor array in series with a load, the current flow through the load can be limited to a predetermined value. This is useful in applications where it is necessary to set a maximum current limit, such as in automotive circuits.

Finally, resistor networks can be used in multiplexers. Multiplexers are electronic circuits that can select one of multiple inputs and make it available as a single output. By connecting a resistor array to an input selector switch or multiplexer, the user can select one of multiple inputs without having to change individual resistors.

Conclusion

The 742C083181JP is a resistor network used in high reliability hybrid circuits, such as automotive, military, medical and telecom products. It is designed to withstand temperatures up to +85 degrees Celsius and has an insulation resistance rating above 100 Mohm at 500V dc. The resistor array is designed to provide high accuracy with lower resistance values, and is used in applications requiring precise voltage division, current limiters, and multiplexers.
