Resistor Networks, Arrays have a wide range of applications in many fields such as electronics, automotive, avionics, military and aerospace industries. Among them, the 4820P-1-270 are especially popular due to their advantages in size, power dissipation, frequency range and resistance value.

4820P-1-270 is a miniaturized hard-mount package consisting of four resistor elements in parallel. Its size is just 6.0mm (L) x 12.1mm (W) x 2.5mm (H), much smaller than the standard 20 pin component. Its power dissipation capacity is up to 10watts, and its frequency range is from 100kHz to D.C. Moreover, its resistance value can be customized and is usually between 1.0kΩ and 47.5KΩ.

As a resistor array, its working principle can be divided into two stages. First, when two ends of the resistor element are connected to a circuit and set to a certain voltage, electrons will flow through the resistor element, generating heat due to the energy loss that occurs when passing through the resistor. The heat generated will be dissipated from the device and is usually proportional to the resistance and voltage applied.

Second, after the current passes through the resistor element, it will go through its inductors and capacitors in order to reduce the resonance and eddy-current losses. The inductors and capacitors will absorb and store the energy due to their high reactance and thus reduce the flow of the current through the resistor. In this way, more power can be dissipated without any extra energy requirement.

In conclusion, the 4820P-1-270 provides an ideal solution for many applications where size and power dissipation are a concern. Its miniature package, wide frequency range and customizable resistance value make it an ideal choice for various applications.
