The 4814P-3-102/102LF Resistor Network, or Array, is used to provide an active current limiting function to protect sensitive electronic equipment. The function of the Resistor Network is to control the current in a circuit, allowing current to pass or to be reduced as necessary. In this way, the Resistor Network can protect the equipment in the circuit from over current or short circuits.

The 4814P-3-102/102LF is composed of six resistors in a network configuration that form a Wheatstone bridge. The resistors are connected in such a way that the resistance of the network can be varied by changing the position of one of the resistors. The bridge is formed by two parallel resistors R1 and R2 connected across the two ends of the resistor array. The other four resistors are connected perpendicular to the two parallel resistors and form the four arms of the bridge. This configuration allows the resistance of the network to be varied by changing the position of the one resistor that is connected between the two parallel resistors.

The 4814P-3-102/102LF is intended for use in circuits with a current rating of up to 3A. The maximum voltage rating is up to 12V. In addition, the rated resistance of each resistor is 10 Ohms. This means that the total resistance of the network can be varied from 10 Ohms to 60 Ohms in increments of 10 Ohms.

The working principle of the 4814P-3-102/102LF is as follows. When the circuit is energized, the current will flow through the network and the current limiting function will be activated when the current reaches a certain level. At this point, the bridge will begin to adjust the voltage drop across the network, thus limiting the current. The current limiting values for the bridge range from 3A to 6A depending on the position of the one adjustable resistor.

The 4814P-3-102/102LF Resistor Network is used in a variety of applications including automotive, industrial, and audio/video systems. For automotive applications, the array is used to limit the current to motors and pumps, as well as providing overload and short circuit protection. In industrial systems, the array is used in current monitoring and control situations. For audio/video systems, the network is used to protect amplifiers and other components from over current and short circuits.

The 4814P-3-102/102LF Resistor Network is an invaluable tool for electronic engineers and is commonly used in a wide variety of applications. By understanding the working principle and application fields of this device, engineers are able to incorporate the array into their designs to provide protection, current limiting, and other useful functions.
