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.
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.
