Resistor Networks, Arrays are widely used as voltage dividing devices in automation systems. RT1235B7TR7 is one type of such miniature resistor networks, which is used to implement custom-design voltage dividing or bucking functions. This resistor network combines seven resistors to divide a high voltage input into seven equal parts, making it an ideal choice for high voltage applications requiring nine consecutive resistance values.

RT1235B7TR7 features a 7-resistor network in a surface mount 1206 package, allowing the resistors to be placed directly onto the printed circuit board without the use of connectors. The resistor values are available in two different configurations to suit different high voltage requirements. For applications like proportional control, the resistance values in the resistors can be selected to suit the specific application.

The resistor network also features a low temperature coefficient, making it suitable for high temperature applications. It is also resistant to shock and vibration, providing a long product life. The resistors have a wide operating temperature range, from -55°C to +125°C, making it suitable for high temperature applications.

The RT1235B7TR7 has a wide operating voltage range of 18V to 52V, making it suitable for use in high voltage applications. It can also be used for Level Shifting from different voltage levels, providing an alternative to clunky DC/DC converters. This makes it suitable for applications where multiple voltage levels need to be transitioned between.

The RT1235B7TR7’s working principle is a simple voltage division circuit. When the voltage is applied across the resistors, the current is limited by the resistance of the individual resistors. The voltage across each resistor is proportional to the resistance value, which can then be used to build a resistance divider circuit. The series resistor network is used to divide the input voltage to the different desired output voltages.

In addition, the RT1235B7TR7 resistor network can be used for other applications such as current limiting and isolation, enabling the isolation of multiple power sources. It can also be used to stabilise the output voltage when a load changes. The wide operating voltage range also makes it suitable for power supply regulation.

The RT1235B7TR7 resistor network is a versatile device that can be used for a variety of high voltage applications. Thanks to its small size, it is an ideal choice for applications where space is at a premium. Its combination of features makes it suitable for high voltage applications requiring nine consecutive resistance values.
