Unfortunately, most surface-mount crystals do not come in named packages. A notable exception is the HC-49US package. This page contains info on the unnamed SMD crystal packages, which are usually identified by their widthlength. There are a variety of popular widthlength combinations used.

SMD Crystal Packages

Table of common SMD 2 pad crystal package dimensions:

Dimensions (width x length)

7.0x5.0mm (2-Lead)

  • Dimensions: 7.0x5.0mm
  • Num. leads: 2
  • Connection type: Pads

This is a common larger SMD package for crystals. There is also a 4-Lead package with the same outer dimensions.
