Crystals Procurement Notes

Verify that the specific METC suffix corresponds to the 9 pF load capacitance and 2.0x1.6 mm package dimensions required by your design. Confirm compliance with RoHS directives and check for any recent Product Change Notifications from TXC Corporation regarding material or process updates. Ensure the selected variant matches the thermal and electrical specifications of the target application environment.

Crystals Selection Notes

Select this component when a small form factor is critical alongside standard industrial temperature operation. The 9 pF load capacitance requirement must align with the host circuit's oscillator input parameters. Consider the 80 Ohm ESR value to ensure proper oscillation startup conditions are met within the system design constraints.
