Crystals Procurement Notes

Verify the manufacturer designation carefully, as the part number 7A-25.000MAHE-T appears in distributor listings under both FTS and TXC Corporation. Confirm that the specified ESR matches your circuit requirements, noting discrepancies between listed values of 50 Ohms and 80 Ohms in different sources. Ensure the package footprint aligns with your PCB layout constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a 25 MHz fundamental mode crystal is required for space-constrained designs. The 2-SMD no-lead package offers a compact form factor suitable for high-density boards. Consider the ±30 ppm stability requirement against your system's jitter tolerance. Verify thermal compatibility with the -40°C to +85°C operating range for your specific environment.
