IEC60603

IEC 60603 is an international standard published by the International Electrotechnical Commission (IEC) that specifies the dimensions and ratings of standard sizes of fixed resistors. The standard is part of the IEC 60000 series, which covers electrical and electronic components and general standards.

The standard defines the physical dimensions, tolerance, temperature coefficient, and power rating for resistors of various sizes. It includes both axial-leaded and surface-mount (SMD) resistors. The standard also specifies the color coding for resistor values, which is a common practice in electronics.

IEC 60603 is widely used in the electronics industry as a reference for the design and manufacture of resistors. It ensures consistency and compatibility among different manufacturers and suppliers. The standard is regularly updated to incorporate new technologies and advancements in resistor design.

The standard is applicable to resistors used in a wide range of applications, including consumer electronics, industrial equipment, and telecommunications. It is an essential reference for engineers, designers, and manufacturers in the electronics industry.
