Resistor Networks, Arrays

The CRB2A4E750JT is a resistor network designed to simplify complex cabling problems. A resistor network is a sequence of resistors connected in series and/or parallel with their values chosen to meet specific requirements. The resistor network can be used in many different applications, such as voltage dividers, current dividers, temperature sensing, and in the development of complex waveforms. A resistor network can also simplify circuitry by replacing a large number of individual resistors with a single network.

The CRB2A4E750JT is a 4-resistor network with its corner-to-corner resistor value set at 750 ohms. This network is designed for general purpose use in applications where several resistors connected in series and/or parallel would be too cumbersome. The network provides a total of 4 resistors of a value of 750 ohms each, with two connected in series and two connected in parallel. The network is constructed on an epoxy-coated ceramic substrate for which the temperature coefficient of resistance (TCR) is +/- 200 ppm/°C. This network also features low thermal EMF, low temperature sensitivity, and low cost.

The working principle of the CRB2A4E750JT is simple. When a voltage is applied, the current flowing through each resistor within the network is divided in two parts, one connected in series and the other connected in parallel. This division of current is determined by the values of the two resistors connected in each part - the total current is divided proportionally based on the resistor values. If one of the resistors in one part has a value of twice that of the other resistor, then two thirds of the current will pass through it.

The CRB2A4E750JT is primarily used in applications such as voltage dividers or current dividers. For a voltage divider, the network can be used to divide a voltage into two parts - one part being a constant voltage and the other a variable voltage depending on the load applied. For a current divider, the network can be used to divide a current into two parts - one part being a fixed current and the other a variable current dependent on the load applied. In each of these applications, the ratio of current division to voltage division remains the same.

In addition to voltage and current dividers, the CRB2A4E750JT can be used in applications such as temperature sensing, frequency division, and waveform development. The network is particularly well-suited for temperature sensing application, as it’s designed for use in environments ranging from -55°C to +125°C. When used as a temperature sensor, the device’s output is proportional to the temperature measured, making it ideal for applications such as HVAC, automotive, construction, and consumer electronics.

The CRB2A4E750JT is a versatile device that can be used for multiple applications. Its simple design and low cost make it an attractive option for applications where a large number of individual resistors would normally be needed. Its low thermal EMF and low temperature sensitivity mean it can be used in demanding environments, making it a highly reliable solution for temperature sensing and other applications.
