Crystals Procurement Notes

Verify that the specific part number matches the required load capacitance and frequency tolerance specifications for the target circuit design. Confirm compatibility with standard reflow soldering profiles and ensure storage conditions adhere to manufacturer guidelines to maintain moisture sensitivity level integrity prior to assembly.

Crystals Selection Notes

Select this component when a compact 3225 footprint is required alongside strict frequency stability requirements over wide temperature variations. Ensure the host oscillator circuit can accommodate the 10 pF load capacitance and that the drive level remains within the 10 uW limit to prevent frequency drift or component damage during operation.

Crystals Part Context

This device belongs to the 7V series of ceramic and glass-sealed crystals manufactured by TXC Corporation. The series is designed for general-purpose applications where size constraints and reliability are critical. The 7V-18.432MAHQ-T specifically addresses common baud rate frequencies used in serial communication interfaces.

Crystals Replacement Considerations

Compatible substitutes include other 3225 SMD crystals with identical 18.432 MHz frequency, 10 pF load capacitance, and ±30 ppm stability. Verify that alternative components meet the same ESR and temperature range specifications to ensure electrical equivalence.
