4420P-T02-681

A resistor network, also known as a resistor array, is an arrangement of multiple resistors connected in a combination that produces a desired amount of resistance to current flow. Resistor networks are used in many applications, including circuit protection, electrical impedance matching, and current and voltage regulation. They are also used in some communication systems.

One example of a resistor network is the 4420P-T02-681. This unit is a 120 ohm resistor array which is housed in a 8 pin, round PTC package. This device has two selectable terminals and one common terminal. It has a low temperature coefficient, high power rating, and is designed for general purpose applications such as voltage regulation and current balancing.

The working principle of the 4420P-T02-681 is relatively simple. As the voltage across the device increases, the desired resistance is obtained by virtue of the two selectable connectors, each of which can be switched in to produce varying amounts of resistance. This allows the device to be used in applications where the desired resistance is not known ahead of time and must be adjustable on the fly, such as voltage regulation and current balancing.

The applications for this device are numerous. It can be used in a variety of circuit protection applications such as transient suppressors, voltage regulators, and surge protectors. It is also used in current balancing applications such as EMI filters, switch-mode power supplies, and LED drivers. In addition, it can be used in various communication systems, including Ethernet cables, coaxial cables, and other wiring configurations.
