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 width*length. There are a variety of popular width*length combinations used.
1. SMD Crystal Packages
Dimensions (width x length) |
---|
1.20x1.00mm |
1.60x1.00mm |
2.00x1.20mm |
2.05x1.20mm |
3.20x1.50mm |
4.10x1.50mm |
Dimensions | Num. terminals, connection type | Image | Comment |
---|---|---|---|
1.5x0.8mm | 4, BGA | ![]() Figure 1. 3D render of the SiTIME SIT1532AI-J4-DCC-32.768E in the 1.5x0.8mm CSP BGA package. Image from https://nz.element14.com/sitime/sit1532ai-j4-dcc-32-768e/osc-32-7khz-1-5-x-0-8mm-lvcmos/dp/2850210. | |
3.2x2.5mm | 4, Pads | ![]() Figure 2. 3D render of the Abracon ABM3B-8.000MHZ-10-1-U-T in the 3.2x2.5mm SMD crystal package.
