 | Ecliptek surface mount crystalsSurface Mount Crystals from 32.768kHz to 70.000MHz
A surface mount crystal can be used in an oscillator circuit to operate in either of two resonant modes: Series Resonance or Parallel Load Resonance (also known as anti-resonance). The surface mount crystals used in these two types of modes are physically the same crystal, but calibrated to slightly different frequencies. |

The Mode of Operation of a thru-hole crystals quartz device is one of the factors that will determine the frequency of oscillation. For "AT" cut thru-hole crystals, over tone modes are at odd frequency harmonics. For example, a crystal may operate at its fundamental frequency of 10 MHz, or at odd harmonics of approximately 30MHz (Third Overtone), 50MHz (Fifth Over tone), and 70 MHz (Seventh Overtone). |
