Crystals Procurement Notes

Verify the specific suffix HC against official TXC documentation to confirm the exact load capacitance and electrical parameters, as suffix variations can alter specifications. Ensure compatibility with the target circuit's load capacitance requirements before integration. Confirm RoHS compliance status through current manufacturer datasheets. Check for any recent product change notices that might affect pinout or material composition.

Crystals Selection Notes

Select this component when a 25 MHz reference with ±30 ppm stability is required in a 3.2x2.5mm footprint. The 9 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for driving capability. This part is suitable for general consumer electronics and industrial applications operating between -40°C and +85°C where moderate precision is sufficient.

Crystals Part Context

This component belongs to the 7M series of SMD seam sealing crystals from TXC Corporation. These units are characterized by high precision and high-frequency stability. The series is designed for applications demanding reliable performance in compact electronic devices. The 7M series represents a standard offering for fundamental mode quartz crystals in surface-mount packages.

Crystals Replacement Considerations

The 7M-25.000MAHJ-T is documented as a similar alternative within the same series. Verify if the J suffix indicates a different load capacitance or tolerance compared to the HC variant. Cross-reference electrical parameters such as ESR and frequency stability to ensure functional equivalence in the target application.
