Resistor networks, arrays, and other components are widely used in electronic circuits. This article focuses on one particular component, the TC164-JR-07120RL. Before exploring its application field and working principles, it is important to understand what a resistor network is and how it works.

A resistor network is an array of resistors that is used to limit current, divide voltage, control currents, and produce accurately adjustable voltages and currents. The resistors can be arranged in a variety of configurations, but the most common ones are the series and parallel resistor networks. In series, a single voltage source is applied to the two extreme resistors, while in parallel, individual voltages are applied to each resistor.

The TC164-JR-07120RL is a resistor network specifically designed to provide high-precision voltage and current division. It consists of a 12-resistor network, each resistor having a value of 470 Ohms, and each network in the array having a parallel resistance of 20 Ohms. It has a power dissipation rating of 1.5 W and a maximum operating temperature of +125°C.

The TC164-JR-07120RL has multiple applications. It can be used to provide accurate voltage and current division in power circuits, and as an adjustable voltage divider in voltage regulation systems. Additionally, it can be used to provide low AC impedance match between high-power loads and electronic sources, and to protect other electronic components from inrush currents and spikes.

The working principle of the TC164-JR-07120RL is based on the parallel resistor network. When a voltage is applied to the array, the voltage drops across each resistor is equal, so the voltage at each of the nodes of the array is the same. The current that flows through each resistor depends on its resistance, so the total current passing through the array is also equal. The ratio of the current passing through each resistor is directly proportional to the resistance of the resistor. This allows for precise adjustment of the currents and voltages passing through the array.

In summary, the TC164-JR-07120RL is a resistor network specifically designed to provide high-precision voltage and current division. It has multiple applications, including power circuits, voltage regulation systems, low AC impedance matching, and protection of other electronic components. Its working principle is based on the parallel resistor network, where the current passing through each resistor is directly proportional to its resistance and thus can be precisely adjusted.
