Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging options such as cut tape or reel quantities. Confirm that the designated load capacitance aligns precisely with the host circuit design requirements before finalizing procurement orders to prevent frequency deviation issues during implementation.

Crystals Selection Notes

Select this component when a compact MHz crystal is required for standard digital timing applications. Ensure the operating environment remains within the specified -20°C to +70°C range. Verify that the system oscillator circuit can support the 10 pF load capacitance and 50 ohm ESR specifications to guarantee reliable startup and sustained oscillation performance.

Crystals Part Context

This part belongs to the 7M series of MHz quartz crystals manufactured by TXC Corporation. The series is characterized by its small physical footprint and seam seal technology, which distinguishes it from larger through-hole alternatives. It serves as a dedicated frequency reference for high-speed digital systems requiring precise timing signals in space-constrained designs.

Crystals Replacement Considerations

Cross-reference with other 32.768 MHz MHz crystals in the 3.2x2.5mm SMD package. Verify identical electrical parameters including load capacitance, ESR, and frequency tolerance before substitution.
