Resistor networks and arrays provide options for designers to integrate a variety of resistive functions in a single package. The 4608X-101-561 is a product in this category that is particularly suited for precision current-sensing applications. In this article, we\'ll look at the field of application and working principles of the 4608X-101-561.

The 4608X-101-561 is a low-profile thick-film resistor array that consists of two terminals and eight isolated resistors that are connected in parallel and in series. The construction is based on the use of a high-temperature co-fired ceramic substrate and nickel electrodes that are hybrid assembly with resistive materials. The standard rating of the 4608X-101-561 is 1.0MΩ to 200MΩ. It is also available in 0.1MΩ to 200MΩ range, depending on customer requirements.

In precision current-sensing applications, the 4608X-101-561 provides maximum accuracy combined with high repeatability and long-term stability. The low temperature coefficient of resistance is ideal for accurate current measurement, ensuring that the current readings remain consistent over time. The resistance values range from 0.5Ω to 200MΩ, with a maximum accuracy of 0.2% and a temperature coefficient of resistance of 40ppm/°C. The device also offers high isolation voltage and current ratings of more than 3000V and 1A respectively.
