Crystals Procurement Notes

Verify the specific ordering suffix when sourcing this component. Suffixes such as 'A' or 'S' indicate different production versions, where 'S' denotes engineering samples and 'A' represents mass production units. Ensure the requested version matches the intended manufacturing stage to avoid discrepancies in BOM validation and long-term supply consistency.

Crystals Selection Notes

Designers must account for PCB trace stray capacitance, typically 2 to 3 pF, when calculating external matching capacitors. Incorrect load capacitance selection can cause frequency deviation beyond specifications. Additionally, ensure the driving power remains within recommended limits to prevent accelerated aging or crystal damage during operation.

Crystals Part Context

This part belongs to the TXC 8Y series, which specializes in extremely small ceramic crystal units. The series is characterized by its seam-sealing technology, offering better thermal shock resistance and hermeticity than standard resin-sealed crystals. It targets markets requiring miniaturization without compromising timing accuracy.

Crystals Replacement Considerations

Direct replacements should be sought from the same 8Y series family with identical dimensions (2.0x1.6x0.5mm) and seam-sealing construction. Verify that substitute parts maintain the 12 pF load capacitance and 26 MHz frequency to ensure circuit compatibility.

Crystals FAQ

What is the difference between the 'S' and 'A' suffixes for this part?

The 'S' suffix indicates an engineering sample version, while the 'A' suffix denotes the mass production version. Users should specify the 'A' version for final product manufacturing.

How does the seam-sealing process benefit this crystal?

Seam sealing provides better hermeticity and thermal stability compared to resin sealing, resulting in lower frequency drift during reflow soldering and harsh environmental conditions.
