The popular 4420P-2-472LF 4 terminal resistor network, also known as the low-profile 472LF, is a device that can be used in a variety of applications. It is a cost-effective solution for those looking to reduce the number of separate resistors needed in a project or device. The 4420P-2-472LF is suitable for use in power supply, high voltage, the automotive, communication and industrial/commercial applications due to its low profile, high power rating and excellent temperature stability.

The network consists of four resistors connected in an array. The 4420P-2-472LF features a single on-chip resistor structure for each terminal, meaning the resistance value can be adjusted by adjusting the on-chip resistor value. Its resistance range is between 0 Ω and 4.7 k Ω. The network is comprised of a resistive element and a capacitor combined in the same package. The resistive element is a four-terminal network with a total resistance of 4.7kΩ. The capacitor is a surface-mount MLCC with a capacitance of 0.1 μF.

The network is constructed in a low-profile package with four terminals which are connected internally forming a resistor ladder. This resistor ladder is implemented using four on-chip resistors, each of the same value. This allows the resistance of the network to be adjustable from 0 to 4.7 k Ω through the selection of different resistor values. The 4420P-2-472LF is capable of providing up to 70W of power in a single package.

The network is constructed in such a way as to ensure that its electrical characteristics remain constant over a wide temperature range. This, coupled with its low-profile, makes the 4420P-2-472LF suitable for use in high temperature and high voltage applications. The network also has excellent power and voltage rating capabilities.

The 4420P-2-472LF is designed to provide a high level of resistance stability over a wide temperature range. It has a high temperature coefficient of resistance, which is important in applications where large amounts of current are to be delivered in a reliable and safe manner. The network offers a low output impedance, which is useful in controlling signal transitions and providing high accuracy. Additionally, the network features a high power rating and excellent current stability.

The network’s working principle is based on the use of the resistor ladder network. The four resistors are connected in series and the current flowing through each resistor is mainly determined by the resistors’ value. The resistance value is adjusted by selecting different resistor values. This ensures that the current flowing through the resistor network is precisely controlled in order to achieve a specific resistance value.

The 4420P-2-472LF is a reliable and cost-effective solution for those looking to achieve accurate and precise control in their projects. It is suitable for use in a variety of applications, from power supply, automotive and communication, to industrial/commercial applications due to its low profile, high power rating and excellent temperature stability.
