Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the selected variant matches the intended operating temperature range and drive level requirements for the target application circuit. Cross-reference the package dimensions with the PCB footprint library to prevent mechanical interference during assembly.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency is required for surface-mount designs. Ensure the system oscillator circuit supports the specified 10 pF load capacitance to achieve accurate frequency output. Verify that the operational environment remains within the -30°C to +85°C range to maintain the stated ±10 ppm stability. Consider the physical size constraints of the 3.2 mm x 2.5 mm package relative to available board space.

Crystals Part Context

This part belongs to the 7M series of miniature quartz crystals from TXC Corporation. The series is characterized by small form factors suitable for modern portable devices. The METQ suffix typically denotes specific packaging and termination characteristics defined by the manufacturer for surface-mount integration.

Crystals Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 3.2x2.5 mm package, and 10 pF load capacitance. Verify equivalent frequency stability and temperature range specifications before substitution.
