Crystals Procurement Notes

Verify the specific suffix and packaging configuration against official Diodes Incorporated documentation prior to ordering. Confirm that the required frequency tolerance and temperature range align with the target application specifications. Ensure compatibility with standard surface-mount reflow soldering profiles to maintain component integrity during assembly processes.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with 20 pF load capacitance is required. Consider the 50 PPM stability limit and -20°C to +70°C operational range for environmental suitability. Evaluate the 60 Ohm ESR and 100 uW drive level against the host oscillator circuit requirements to ensure proper startup and sustained oscillation without overdriving the crystal.

Crystals Part Context

This part belongs to the NKS7 series of ceramic crystals from Diodes Incorporated. The series provides standard frequency solutions for consumer and industrial electronics. The NKS7-250-20(T) specifically addresses the common need for 25 MHz timing references in surface-mount designs, offering a balance of performance and physical footprint for modern electronic assemblies.

Crystals Replacement Considerations

Cross-reference with other 25 MHz, 20 pF load capacitance ceramic crystals from Diodes Incorporated or alternative manufacturers. Verify dimensional compatibility and electrical parameter equivalence, including ESR and drive level, before substituting to ensure circuit functionality remains unaffected.
