Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official part number guide to ensure correct packaging and specifications. Confirm that the required frequency tolerance and load capacitance match the target circuit design before procurement. Check current availability status as automotive-grade components may have extended lead times or allocation constraints depending on regional demand.

Crystals Selection Notes

Select this component when a fundamental mode crystal with high frequency stability is required for automotive environments. Ensure the host oscillator circuit can drive the specified 60 Ohm ESR and matches the 8 pF load capacitance requirement. Consider the -40°C to +85°C operating range to verify compatibility with the expected environmental conditions of the final application.

Crystals Part Context

This part belongs to the AV series of automotive crystals from TXC Corporation. These components are specifically engineered to meet the rigorous quality and reliability standards defined by AEC-Q200.
