Crystals Procurement Notes

Verify the specific ordering suffix matches the required load capacitance and tolerance specifications. Confirm the package dimensions align with the target PCB footprint. Ensure the temperature range meets the operational environment requirements. Check for RoHS compliance status if mandated by project standards. Validate supplier authenticity through authorized distribution channels to guarantee component integrity.

Crystals Selection Notes

Select this component when a cost-effective alternative to crystal oscillators is needed for non-critical timing applications. Consider the higher ESR compared to crystals when designing drive levels. Evaluate the frequency stability requirements against the ±0.5% tolerance. Ensure the load capacitance matches the circuit design parameters. Assess thermal constraints within the specified operating range.

Crystals Part Context

This ceramic resonator belongs to TXC's general-purpose timing component lineup. It serves as a simpler, lower-cost solution compared to quartz crystals for applications where high precision is not paramount. The 7M series typically offers a balance between performance and manufacturability. It is commonly used in mass-produced electronics where size and cost are significant factors. The model designation indicates specific pin configuration and mounting style.

Crystals Replacement Considerations

Direct substitutes must match the 12.288 MHz frequency, 30 pF load capacitance, and SMD-3L package. Verify equivalent ESR and shunt capacitance values to ensure circuit compatibility. Cross-reference with other manufacturers' ceramic resonators offering similar tolerance and temperature ranges. Ensure pinout compatibility for seamless PCB replacement.
