Resistor Networks, Arrays

The 4310R-102-272 is a type of resistor network, array and often referred to as a resistor array. This particular resistor array is notable for its small and low-profile design. It allows for a high density of resistors on a smaller total area than would otherwise be possible. This type of resistor array is used in very precise circuits where closely set and single value resistances are needed in order to get a very precise response. It also has relatively low costs compared with other types because it does not need to be moved or replaced as frequently as other types.In a circuit or device, a resistor network is two or more resistors connected in parallel or series, forming more than one node within the network. A resistor array is just like a regular resistor network, except it has multiple nodes of resistors in order form a more complex circuit. In the case of the 4310R-102-272, this particular array has 102 individual resistors of 1/4 watt each arranged in seven sets of fourteen resistors.

Applications

The 4310R-102-272 is most commonly used in a range of high-precision and high-density circuits that make use of small and closely-set resistors. This type of array is often used in electronic instrumentation, radio frequency (RF) directional couplers, sensors, measuring devices, and in automotive, avionic and aerospace systems. It is also used in noise reduction and signal processing applications, as well as in signal strength measurement instruments and signal conditioning circuits.

Working Principle

The operation of the 4310R-102-272 relies on the presence of a resistor at every node or contact point in the network. The resistance of each resistor is set in relation to the other resistors in the array such that it forms a specific resistance value across the array as a whole. When a current passes through the array, each individual resistor is activated and absorbs some of the current. The amount of current absorbed by each resistor depends on its resistance value and the total current drawn from the array. The amount of current drawn from the array is dependent on the load connected to the array. When the resistance of the load is greater than the total resistance of the array, a greater proportion of the current flows through each resistor and less is drawn from the array. Conversely, when the resistance of the load is less than the total resistance of the array, a smaller proportion of the current flows through each resistor and more is drawn from the array. This behaviour is exploited to create a variety of different circuits. By connecting different resistors to the array, the current flow can be tailored to achieve specific desired results. This is especially useful in precision and signal processing applications. For instance, by connecting a resistor of a certain resistance value, the amount of current flowing through the array can be regulated in order to achieve the desired signal processing or noise reduction result.

Conclusion

The 4310R-102-272 resistor array is a useful component in high-precision and high-density circuits due to its small and low-profile design. It is often used in electronic instrumentation, radio frequency (RF) directional couplers, sensors, measuring devices, and in automotive, avionic and aerospace systems. Its operation relies on the presence of a resistor at every node or contact point in the network, and the behaviour of the network can be manipulated by connecting different resistors to the array.
