YC324-FK-0754R9L

Resistor Networks, Arrays are essential components when constructing an electrical circuit. By taking the YC324-FK-0754R9L from Yageo as an example, let\'s take a look at the application fields and the working principle.

YC324-FK-0754R9L is a special surface-mount resistor array. It consists of 25 resistors packaged in one package. It has an electrical resistance range of 0.25Ω to 5.1Ω. The element type of its sub-resistors is film resistor and their tolerance is ±1%. In addition, its rated voltage is 200V, which meets the insulation requirements of high-voltage resistors. This resistor network is mainly used in satellite communication, communication base stations, mobile communication systems and other electronic communications related products.

The surface-mount resistor arrays enable installation of multiple resistors in a single device with very tight space constraints. Typically, these arrays are configured in either single-pole network or two-pole network types. As for YC324-FK-0754R9L, it has a two pole network configuration consisting of 25 resistors forming a set of 12 pairs. Two terminals are connected with pairs of resistors in series, so the total resistance of the resistor array is equal to sum of all the resistor’s resistance.

The working principle of YC324-FK-0754R9L relies on the fact that the total resistance of a series connection of resistors is equal to the sum of the individual resistors. When current flows through a series connected resistor network, the applied voltage is split between the resistors. This voltage division is inversely proportional to the resistance of each individual resistor. By changing the value of the individual resistors in the network, the total resistance of the network can be adjusted and the flow of current can be regulated accordingly.

The concepts and principles around resistor arrays and resistor networks have been known for a very long time. Applications ranging from data communications to home audio systems use resistor networks and arrays for a variety of purposes, including signal conditioning, gain scaling and attenuation. With advances in microelectronics, designing and constructing resistor networks have become easier and more cost effective than ever.

Resistor arrays and networks are valuable components on printed circuit boards and they show their worth almost everywhere in our lives. Thus, understanding of their application fields and working principles is very important, which helps us find the right product for the job.
