RG series

The RG series refers to standardized ranges of resistors used in electronic circuits, categorized by their resistance values and power ratings. Each RG series (like RG-55, RG-174, etc.) specifies a set of resistor values that are spaced according to a mathematical sequence, helping engineers select components that match precise design requirements while ensuring consistency and compatibility across projects. These series simplify the process of choosing resistors with standard values, reducing the need for custom components and making manufacturing and maintenance more efficient.
