How do I know my SMD size?
SMD Resistor Sizes The size of SMD resistors is indicated by a numerical code, such as 0603. This code contains the width and height of the package. So, the imperial code 0603 indicates a length of 0.060″ and a width of 0.030″. The SMD package code can be given in either imperial or metric units.
What are the dimensions of a 1206 surface mount resistor?
3.0 x 1.5 0.12 x 0.06
SMD resistor packages
| Common Surface Mount Resistor Package Details | ||
|---|---|---|
| Package style | Size (mm) | Size (inches) |
| 1206 | 3.0 x 1.5 | 0.12 x 0.06 |
| 0805 | 2.0 x 1.3 | 0.08 x 0.05 |
| 0603 | 1.5 x 0.08 | 0.06 x 0.03 |
What size is an 0603 component?
The standard dimensions of an 0603 package are: Length: 1.55 ± 0.05 mm. Width: 0.85 ± 0.05 mm. Height: 0.45 ± 0.05 mm.
What is EIA spacing?
The horizontal spacing of the vertical rows of holes is specified by EIA-310 at 18 & 5/16″, or 18.312”, which equates to 465.1 mm. The vertical spacing is defined as a repeating pattern of holes 0.625” apart within one rack unit of 1.75”.

What is a MELF package?
Metal electrode leadless face (MELF) is a type of leadless cylindrical electronic surface mount device that is metallized at its ends. MELF devices are usually diodes and resistors.
What is SMD packaging?
SMD package types describe the physical characteristics of devices that use surface mount technology (SMT) for attaching electronic components directly to the surfaces of printed circuit boards (PCB). In other words, an SMD is an electronic component that attaches to a PCB with SMT.
What to look for in a 0402 package footprint?
A 0402 package footprint needs to be carefully designed in your CAD tools to complete your PCB layout successfully. Here’s what to watch for in a 0402 package footprint and where you can find verified footprints for all your components. The 0402 package is nearly the smallest chip resistor package; only the 0201 chip resistor package is smaller.
What’s wrong with the 0402 component?
There’s something about the 0402 component that just loves to drive us insane! The issue is that many footprints inadvertently cause the component to “tombstone” or worse “head-in-pillow”. Here’s what those defects look like. This is what a “Head-In-Pillow” defect looks like. Notice how the right side isn’t actually wetted to the component.
Is the 0402 the most sinister of all footprints?
With this amount of new work, we’ve seen the good, the bad, and the downright ugly when it comes to footprints. The most sinister of all footprints is the 0402 footprint (see also ” The Perfect 0201 Footprint ” article, as the 0201 is the new 0402).
What is an 0402 resistor?
If you have experience working with SMD components, you’re probably familiar with chip resistors and their wide range of package sizes. Among the smallest, and yet most popular, is the 0402 resistor, and its very small footprint with SMD pads.
