Resistor Networks, Arrays

Resistor networks and arrays are groups of resistors, or individual resistors that have been connected in various ways to form networks. These networks can be used to perform a variety of functions such as current regulation, voltage regulation, and frequency control. The RT1412B7TR7 resistor network is a 4-terminal resistor array typically used as voltage dividers or current limiters. This network combines a single resistor array with a voltage tap, giving it a high degree of flexibility and accuracy.

Application Field

The RT1412B7TR7 resistor network is a versatile network applicable to a wide range of voltage dividers and current limiters. It can be used in applications such as thermostats, lighting control systems, motor controls, audio circuits, and precision metering. This network is also used in automotive and industrial applications such as in power supplies, solar controllers, and motor drives.

Working Principle

The RT1412B7TR7 resistor network acts as a resistive network, dividing a voltage across the terminals. The network includes one high-precision, voltage-controlled resistor and three low-tolerance resistors. The resistor values are connected in series and in parallel depending on the configuration, and the voltage division ratio can be changed by adjusting the voltage on the tap. This tap is connected to the high-precision resistor, which has a low temperature coefficient and is stable with changing currents.

The RT1412B7TR7 can also be used as a current limiter. In this application, the voltage is held constant across the terminals and the current is limited by adjusting the tap. This allows the RT1412B7TR7 to be used in sensitive current-regulating circuits, such as those used in electronic metering or current-sensing applications.

Conclusion

The RT1412B7TR7 is a versatile 4-terminal resistor network with applications in voltage division, current regulation, and frequency control. This network can be used in a wide variety of settings due to its high precision and stable performance. It is suitable for both automotive and industrial applications as well as for consumer electronics.
