This page is in notes format, and may not be of the same quality as other pages on this site.

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)
1.20x1.00mm
1.60x1.00mm
2.00x1.20mm
2.05x1.20mm
3.20x1.50mm
4.10x1.50mm

1.5x0.8mm​

  • Dimensions: 1.5x0.8mm
  • Num. leads: 4
  • Connection type: BGA

3.2x2.5mm (4-Lead)​

  • Dimensions: 3.2x2.5mm
  • Num. leads: 4
  • Connection type: Pads

A very common package size for a 4-lead SMD crystal. There is also a 6-lead crystal package with the same length and width of 3.2x2.5mm.

3.2x2.5mm (6-Lead)​

  • Dimensions: 3.2x2.5mm
  • Num. leads: 6
  • Connection type: Pads

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.

7.0x5.0mm (4-Lead)​

  • Dimensions: 7.0x5.0mm
  • Num. leads: 4
  • Connection type: Pads
