Crystals Procurement Notes

Verify the specific suffix 'J' against the manufacturer's current datasheet to confirm package dimensions and terminal configuration. Ensure the selected variant matches the required load capacitance of 18 pF for circuit compatibility. Confirm RoHS compliance status and check for any recent product change notices that may affect physical or electrical specifications prior to final procurement.

Crystals Selection Notes

Select this component when automotive certification is mandatory for the target application. The 18 pF load capacitance requires matching external circuit capacitors to achieve the specified 25 MHz frequency. Consider the 50 Ohm ESR for oscillator circuit stability. This part is suitable for designs operating between -40°C and +85°C where long-term frequency stability is critical.

Crystals Part Context

This crystal belongs to TXC's automotive-certified lineup, distinguished by its adherence to AEC-Q200 stress tests. Unlike standard commercial crystals, it undergoes rigorous validation for thermal cycling and mechanical shock. The 25 MHz frequency is commonly used for system clocks in microprocessors and communication modules, providing a precise timebase for digital logic operations.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 18 pF load capacitance, and AEC-Q200 qualification. Verify that alternative packages maintain identical footprint dimensions to ensure board compatibility without redesign.
