Thru-Hole Quartz Crystals
Thru-hole quartz crystals are used when the application that the crystal is required for, is more demanding in terms of frequency range than SMD (surface mount) crystals are suitable for. These crystals are commonly manually installed, and usually size is not a factor. Thru-hole crystals are suitable for applications where a range of frequencies is required, as opposed to just one very precise vibration frequency.
Choosing a thru-hole crystal will require the following to be specified:
1) The frequency range required (including frequency stability and tolerance specifications)
2) Temperature range requirements
3) Footprint considerations
4) The duration for which the crystal will be required
In addition, temperature and electrical characteristics are more favorable for thru-hole crystals than SMD crystals, which can contribute to the decision to use thru-hole crystals in a specific application.
