    Understanding Quartz Crystal Hermeticity and SC-cut Long-Term Reliability

    April 29, 2025
    Learn how hermetic sealing protects SC-cut quartz crystals from moisture, temperature shifts, and contaminants- ensuring long-term frequency stability, low phase noise, and reliable performance in demanding environments.

    Precision quartz crystal resonators, especially SC-cut designs, must maintain reliability over many years, even when exposed to harsh conditions like temperature fluctuations and environmental contaminants. Without proper protection, these crystals can experience issues such as frequency aging, increased resistance, and unstable phase noise, leading to degraded system performance. Hermetic sealing plays a critical role in safeguarding quartz crystals against moisture and harmful elements, preserving their long-term stability and reliability.

    In this paper, we explore the relationship between quartz crystal hermeticity and SC-cut resonator performance. Learn why proper sealing methods are essential for achieving the highest levels of durability, frequency stability, and phase noise performance in mission-critical RF and microwave applications.
