Chip:This product is a resistor network & array made by Uniroyal Chip containing 4 separate resistors with a value of 2.2KOhms ±5% 1/16W 0603_x4 RoHS. This product is RoHS compliant meaning that the product does not contain any hazardous materials or chemicals such as lead and mercury. The resistors are of a very small size with 0603_x4 dimensions and are extremely thin with only 1/16W thickness meaning they are very lightweight. This product is ideal for applications where weight, size, and space are important constraints.
