Resistor Networks, Arrays have various applications and can be used to handle various tasks. This article will discuss 4820P-2-472 application field and working principle.

4820P-2-472 is a resistor matrix with four resistors placed in a single package. It consists of two rows of four resistors. The first resistor in each row is connected to the common terminal, the ground. The other three resistors are connected to the output terminals 1, 2, and 3. The four resistors have a total resistance of 4.72kΩ. The package size is 0.4" × 0.4" and it has a total of four pins.

The 4820P-2-472 has a wide range of applications in the field of electrical engineering, such as in audio and video systems. It is used in applications where a single resistor would be current limited and does not provide adequate power to perform its intended function. For example, it is used in the low-pass filter of an audio system where the damping factor is determined by the resistors connected to the output. It is also used in video systems to reduce the heave image distortion.

The working principle of 4820P-2-472 can be understood by analyzing the network of four resistors. According to Ohm\'s law, the current flowing through each of the resistors is inversely proportional to its resistance.Therefore, the greater the resistance of a resistor, the lesser the current flowing through it. The network of four resistors forms a parallel circuit, wherein the four resistances are connected in such a way that the total current is divided among them equally. This is because, in a parallel circuit, the resistances are connected such that they share the same amount of voltage.

When a voltage is applied to the circuit, it divides the total current equally among the resistors, resulting in a decrease in the voltage across each resistor. This is why the 4820P-2-472 can be used in applications where a single resistor would be current limited and does not provide adequate power to perform its intended function. Additionally, the four resistors can be used to produce different combinations of resistance, allowing the user to adjust the output voltage according to their needs. Additionally, it provides better thermal and voltage stability than other resistor networks.

In summary, 4820P-2-472 is a resistor matrix with four resistors placed in a single package. It has a total resistance of 4.72kΩ and is mainly used in applications where a single resistor would be current limited. Its working principle is based on the network of four resistors, which form a parallel circuit, resulting in an equal sharing of total current among the resistors. This makes it useful for audio and video systems as well as other applications.
