Crystals Procurement Notes

Verify that the specific suffix 'MDHJ' corresponds to the required 18pF load capacitance and ±20ppm tolerance specifications. Confirm the operating temperature range meets the application's environmental requirements. Ensure the driving level does not exceed 10 uW to prevent frequency instability or crystal damage during circuit integration.

Crystals Selection Notes

Select this component when a 25 MHz reference signal is required within a limited board space. The 18pF load capacitance must match the oscillator circuit design. Consider the ±30ppm stability rating against system timing requirements. Verify compatibility with SMT reflow processes due to the ceramic package type.

Crystals Part Context

This part belongs to the TXC 8Z series of surface-mount crystals. The series offers various frequency options and package sizes, typically ranging from 12MHz to 66MHz. The 8Z designation indicates a specific ceramic seam-sealed form factor designed for high reliability in consumer electronics applications.

Crystals Replacement Considerations

Cross-reference with other 25MHz crystals in the 2.5x2.0mm package. Ensure substitute parts match the 18pF load capacitance and 100 Ohm ESR. Verify identical temperature ranges and stability ratings for direct replacement.
