In this regard, a special labeling method was developed. The following table lists the size and specifications The most commonly used SMD resistors.ĭue to the small size of SMD resistors, they are almost impossible to apply traditional color marking of resistors. The size of the SMD resistor depends mainly on the required dispersion power. SMD dimensions of resistors and their power

To translate dimensions in millimeters, enough size in inches to multiply by 2.54. The same type of resistor in the metric system will have code 1608 (in millimeters), respectively, the length is 1.6 mm, the width is 0.8 mm. Thus, in our example, the code 0603 (in inches) the length of the housing is 0.060 inches, a width of 0.030 inches. The code contains information about the length and width of the resistor. The size of SMD resistors is denoted by numerical code, for example, 0603. SMD sizes of resistors Standardized, and most manufacturers use the JEDEC standard. For example, a configuration of a conventional chip, which has a flat housing with a two-sided termination of the conclusions (perpendicular to the base plane), is called DIP. SMD sizes SMD resistorsīasically, the term sizes includes size, form and configuration of outputs (body type) of any electronic component. It eliminates the need to make holes in pCBAnd thereby allows you to more effectively use the entire surface. Instead of wire conclusions of conventional resistors that are inserted into the circuit board holes, SMD resistors have small contacts that are soldered to the surface of the resistor body.

They are often square, rectangular or oval, with a very low profile. SMD resistors are significantly less than their traditional analog.

SMD resistors - These are miniature, intended for surface editing. Today we consider one of these - SMD resistor. Surface Mount Technology) was designed to reduce the production of printed circuit boards using smaller electronic components: resistors, capacitors, transistors, etc. Surface Mounted Device) can be attributed to any small-sized electronic component intended for installation on the SMT technology board surface (surface mounting technology). In general, the term SMD (from the English.
