Decoding SMD Resistor Sizes and Ceramic Capacitors

Understanding the sizes and values of SMD resistors and ceramic capacitors is crucial for electronics enthusiasts and professionals alike. This guide will help you decode the common sizes: 0603, 0805, and 1206, as well as color marking for resistors and inductors.

SMD Resistor Sizes

SMD (Surface-Mount Device) resistors come in various sizes, which are designated by a four-digit code. Here’s a quick overview of the most common sizes:

• 0603: 0.06 x 0.03 inches (1.6 x 0.8 mm)


• 0805: 0.08 x 0.05 inches (2.0 x 1.25 mm)


• 1206: 0.12 x 0.06 inches (3.2 x 1.6 mm)

Color Marking for Resistors and Inductors

Resistors and inductors often use color coding to indicate their resistance values. The standard color code is as follows:
