Resonators Procurement Notes

Verify the specific load capacitance requirement of 15 pF against the target oscillator circuit design to ensure accurate frequency performance. Confirm that the operating temperature range of -20°C to +80°C aligns with the environmental conditions of the end application. Ensure compatibility with SMD/SMT assembly processes and check for RoHS compliance status prior to final procurement authorization.

Resonators Selection Notes

Select this component when a precise 4.72 MHz timing source is required with tight tolerance constraints. Consider the physical dimensions of 4.5 mm x 2 mm for footprint planning. Evaluate the thermal limits to ensure operation within the specified -20°C to +80°C window. Compare against other CERALOCK variants if different load capacitances or frequencies are needed for alternative system designs.
