RT1418B7TR7

Resistor Networks, Arrays form a branch of electronics that utilizes various resistors and connect them in patterns for numerous and varied purposes, such as regulating voltages.

One example of such resistor networks is the RT1418B7TR7. This product is a 7-resistor network that contains four parallel-connected resistors and three series-connected resistors, all of which are connected together in such an arrangement that serves many different functions.

Application Field

The RT1418B7TR7 can be widely used in many fields. It can be used to protect Digital Video Broadcasting receivers from static electricity and to provide transient overvoltage protection for television sets and digital STBs.

In telecommunications equipment, RT1418B7TR7 networks can be widely used for Ethernet terminals, VDSL DSLAMs and switches, and other high-speed data transmission equipment. The resistor networks help protect equipment from overvoltage or lightning surge. In addition, they can also be used to limit inrush current and suppress ESD (electrostatic discharge) if placed in the input terminals.

Working Principle

The RT1418B7TR7 utilizes three series resistors and four parallel resistors to regulate the voltage of the external environment. The series resistors serve to reduce the magnitude of voltage that passes through the resistor network by increasing the voltage drop across the resistor array. The parallel resistors serve to divide the supplied voltage across multiple nodes and reduce the current passing through the system. The four larger 5M5 resistors are connected in parallel, allowing for the same current to pass through each resistor while being divided across the parallel resistors. In addition, the three smaller SMD resistors serve to filter the noise that will pass through the resistor network.

In conclusion, the RT1418B7TR7 is a resistor network that contains seven different resistors arranged in such a way that can be widely used in various applications such as telecommunications, digital video broadcasting, and static protection on consumer electronic devices.
