Resistor Networks, Arrays are commonly used in a wide range of applications including power converters, amplifiers, radio-frequency sources, and video displays. The 4420P-T01-473 is a popular type of resistor network that can be used in a variety of applications. This article will explain the application field and working principle of this type of resistor network.

The 4420P-T01-473 resistor network is a high performance 4-resistor array that is designed for high-reliability, high-voltage, and high-current applications. It is composed of four 200 ohm resistors in a 2x2 configuration with each leg connected to a common output terminal. The common output terminal has a maximum voltage rating of 150V and a maximum current rating of 10A. The resistors in the 4420P-T01-473 offer excellent temperature stability and low-temperature coefficient of 95 ppm/°C, with temperature compensation ranging from -40°C to +85°C.

The main application of this resistor network is in power electronics, such as power supplies, motor control, and other power conversion applications. It can be used to provide current-limiting protection, over-voltage protection, and line-termination in power converters. The resistor network can also be used in motor control applications, such as providing current regulation to protect from overloads and short circuits. Additionally, it can be used in audio amplifier designs to provide current-limiting protection and reduce output noise.

The working principle of the 4420P-T01-473 resistor network is relatively simple but effective. By connecting the four 200 ohm resistors in a 2x2 configuration, a four-resistor network is formed with each resistor having the same resistance value. This gives the resistor network a total resistance of 800 ohms. When a power source is connected to the resistor network, the current flowing through the network is equal to the voltage of the power source divided by 800 (the total resistance of the network). In other words, the current is inversely proportional to the total resistance, which allows the user to control the current flowing through the network by changing the configuration of the resistors. As the resistors are connected in a 2x2 configuration, any changes to the resistance of one resistor will change the total resistance of the network, resulting in a proportional change to the current.

In summary, the 4420P-T01-473 resistor network is a high performance, 4-resistor array that is designed for high-reliability, high-voltage, and high-current applications. It is mainly used in power electronics, such as power supplies, motor control, and other power conversion applications. The working principle of the resistor network is relatively simple, but effective; the current is inversely proportional to the total resistance of the network, which allows the user to control the current by changing the configuration of the resistors. This makes it a versatile and reliable resistor network that provides many benefits to the user in various applications.
