Resistor Networks, Arrays

The RT1211B7TR7 is a small Vishay Sfernice resistor array that consists of seven individual resistors connected in the form of a Bussed resistor network. It offers seven resistors that are tightly fitted and spaced together in a small package with a maximum size of 0.2 inches long and 0.1 inches wide. It is used in a variety of applications due to its wide range of resistance values and excellent accuracy. This resistor array is ideal for creating voltage dividers, filters, and amplifier feedback circuits. It can also be used as part of a thermistor or shunt to measure current.

The RT1211B7TR7 has a power rating of 2.5W, which means it can handle up to 2.5 watts of continuous power, at temperatures ranging from -55°C to +125°C. It has a maximum voltage rating of 250V and has a resistance range of 0.1 to 1Mohms. It also has an excellent accuracy rating of ±5% of the marked value.

Working Principle

The RT1211B7TR7 works by connecting the seven resistors in a Bussed network, which means all of the resistors share a common connection. The resistor network is designed to work as a voltage divider. When you connect a voltage at one end of the network and a ground at the other end, the voltage will be divided proportionally across each resistor based on its resistance. This allows current to flow from one end of the network to the other, so you can accurately measure the voltage or current at any point along the network.

The RT1211B7TR7 can also be used for filters, amplifier feedback circuits, and thermistors. Filters are used to remove unwanted frequencies from a signal, and the RT1211B7TR7 is well suited to this application due to its wide range of resistance values. Amplifier feedback circuits allow you to adjust the gain of an amplifier, and the RT1211B7TR7 is an ideal choice for this application due to its excellent accuracy rating. Lastly, the RT1211B7TR7 can be used with a thermistor to measure temperature.

Applications

The RT1211B7TR7 is commonly used in voltage divider and amplifier feedback circuits. It can also be used in filters to remove unwanted frequencies from a signal. Additionally, it is frequently used with thermistors to measure temperature. It is also suitable for use in automotive and industrial applications due to its wide temperature range and excellent accuracy rating.

The RT1211B7TR7 is a useful and versatile Bussed resistor network that provides an excellent option for a variety of applications. Its small size and wide range of resistance values makes it an ideal choice for projects that require accuracy and precision. With its power rating of 2.5W, and temperature range of -55°C to +125°C, it is suitable for both commercial and industrial use.
