Resistor networks, arrays and the like are components used in a wide variety of applications, from simple voltage dividers to more complex distributed power systems. One particular type of resistor network is the 4820P-1-100LF, a four-terminal resistor network designed for a variety of applications. This article will look at the 4820P-1-100LF’s application field and working principle.

The 4820P-1-100LF resistor network is a four-terminal resistor array fabricated from thick-film elements on a high-temperature substrate. It has a total of 22 resistors, each with a resistance of 0.1 ohms, and a combined resistance of 2.2 ohms. The array has a continuous power rating of 10 watts at 70°C, and an overload power rating of 20 watts for up to 5 seconds, allowing it to handle more than its rated power for short intervals. This makes it a great resistor network for applications such as power amplification, current sensing, and voltage sensing.

The 4820P-1-100LF has a number of different working principles. As a voltage divider, it acts as a linear resistor array, with each resistor providing a unique voltage drop across the network. This is one of its most common applications, since it allows the voltage to be divided into a reliable, repeatable voltage drop. Furthermore, this resistor array can also be used for current sensing and voltage sensing. In this case, each resistor acts as a current or voltage sensor, and the combined resistance of the array acts as a threshold to indicate when the current or voltage exceeds a predetermined value.

The 4820P-1-100LF is also often used in distributed power applications. In this context, the resistor network provides a reliable means of distributing power to different parts of the system. Every resistor in the array adds or subtracts a small amount of power from the system, allowing for accurate control of the power being delivered. This can help reduce manufacturing complexity and costs, as well as help provide a more consistent performance.

Finally, the 4820P-1-100LF is also often used to optimize the performance of multiple-output power supplies. In a multi-output power supply, each output can be optimized for its own device load or for a range of device loads. By incorporating a resistor network of the 4820P-1-100LF type, the power supply designer can optimize each output to match the device’s requirements. This can help to improve the efficiency and performance of the overall system.

In conclusion, the 4820P-1-100LF is a versatile four-terminal resistor network with a variety of application fields and working principles. Its reliability and power handling capabilities make it a great choice for a variety of applications, from distributed power to current and voltage dividers. Furthermore, its ability to optimize multiple-output power supplies makes it a great choice for today’s demanding applications. The 4820P-1-100LF is a great solution for those looking to improve performance and efficiency through careful selection of resistor networks.
