Crystals Procurement Notes

Verify the specific suffix MEEQ-T against the official TXC ordering guide to confirm the exact load capacitance and tolerance specifications. Ensure the selected packaging type matches the production line requirements, as availability varies between reel, cut tape, and Digi-Reel formats. Confirm that the -20°C to +70°C industrial temperature range aligns with the target application's thermal environment before finalizing the procurement order.

Crystals Selection Notes

Select this component when a fundamental mode crystal with high precision is required for space-constrained designs. The 3.2mm x 2.5mm package offers a balance between performance and board area efficiency. Consider the 60 Ohm ESR limit when designing the oscillator circuit to ensure reliable startup. This part is suitable for applications where strict frequency stability is critical but extreme temperature ranges are not required.
