Array resistors are made from a combination of several resistors that are configured into a pattern, one single array resistor can replace four or two single resistors. . Although most array resistors use resistors connected in series, some array resistors use resistors in parallel or series-parallel designs. The resistors in a network act as voltage dividers which divide the voltage that is applied to a circuit into smaller amounts.

Resistor arrays are a type of fixed resistors – devices which are used in electrical circuits to limit the flow of electricity and where the resistance is set at a specific value that can't be changed. Resistors help to prevent other circuit components from being damaged or destroyed.
Array resistors can help reduce mounting area compared to single resistors. Array resistors are convenient when you need several resistors that all have one end connected to the same point in your circuit. The mounting area maybe reduced by up to 58%.They're widely used in electronic applications. The most common applications include:

• Consumer electronics and computers
• Voltage dividers for power supplies
• Analogue-to-digital and digital-to-analogue conversion

Array resistors are widely used as they can help reduce the number of mounting processes as well as mounting time and costs and can also significantly improve SMT productivity. Array resistors have been used by major global semiconductor companies and have been recognized in their quality and performance.
