Crystals Procurement Notes

Verify the specific suffix designations against the official datasheet to confirm temperature range and electrical parameters. Ensure the ordering information matches the required load capacitance and frequency tolerance for the target application. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with manufacturing standards.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with ±30 ppm stability. The wide operating temperature range of -40°C to +85°C makes it suitable for industrial environments. Consider the 18 pF load capacitance requirement to ensure proper circuit oscillation. The small SMD footprint allows for high-density board layouts compared to larger through-hole alternatives.

Crystals Part Context

This part belongs to the 7V series of ceramic crystals from TXC Corporation. The series is characterized by small form factors and reliability for general-purpose timing applications. The 7V-27.120MAHJ-T variant specifically addresses needs for 27.12 MHz signals in compact surface-mount designs, distinguishing it from older 7B series packages or different frequency variants within the same family.
