Resonators Procurement Notes

Verify the specific frequency requirement of 8.5 MHz against system specifications. Confirm that the 33 pF integrated load capacitance matches the target oscillator circuit requirements. Ensure the SMD package dimensions align with the PCB footprint constraints. Check operational temperature limits for the intended environment.

Resonators Selection Notes

Select this component when a precise 8.5 MHz reference is required without external capacitors. Consider the ±0.5% tolerance for general timing applications. Evaluate the 40 Ohm impedance against the driving capability of the host device. Compare performance against crystal alternatives if higher stability is needed.

Resonators Part Context

This part belongs to the CERALOCK CSTNE series, designed as a cost-effective alternative to crystals. It combines piezoelectric ceramic elements with integrated capacitors. The series targets high-volume consumer electronics where moderate stability suffices.
