The MNR12ERAPJ102 is an integrated resistor network and array from Panasonic Electronic Components. It is classified as a current sensing resistor array designed for power resistor applications such as LED lighting. It has a maximum power rating of 150mA at 50V and an adjustable resistance range of 3.3 Ω to 5 Ω. It is comprised of 12 separate rows of resistors and a single ground pin, all of which are connected in series with one another. Each row can be individually adjusted, allowing for a wide range of resistance values and configurations.

The MNR12ERAPJ102 is often used in a variety of power resistor applications, such as LED lighting and other current sensing operations. Its 12 rows of resistors in series can be set to divide the input current into different voltage drops across each resistor, providing the ability to control the output current. The adjustable resistance range of 3.3 Ω to 5 Ω and the maximum current rating of 150mA allow for precise control of the output current. Additionally, the device can be used as a noise filter as well.

The working principle of the MNR12ERAPJ102 is based on the concept of voltage division. As current passes through each resistor, a certain amount of voltage drop is created across it, which is then divided amongst the other resistors in the circuit. The total voltage drops across the resistors is equal to the input voltage, and the sum of the individual voltage drops across each resistor is equal to the total voltage. By adjusting the resistance value of each row, the total current can be precisely controlled.

In conclusion, the MNR12ERAPJ102 resistor network and array is a versatile, current sensing device used in a variety of applications. Its adjustable resistance range and maximum current rating provide precise control over the output current, while its noise filter capabilities ensure reliable operation. Furthermore, its working principle of voltage division enables for the total voltage drop across the circuit to be evenly distributed amongst the individual resistors, making it an ideal choice for LED lighting and other power resistor applications.
