Resonators Procurement Notes

Verify the specific lot code and manufacturing date against project requirements before procurement. Ensure that the ±0.3% stability specification aligns with the system's timing budget, as this component is intended for applications where absolute precision is not mandatory. Confirm compatibility with reflow soldering profiles specified in the official datasheet to maintain device integrity during assembly processes.

Resonators Selection Notes

Select this component when a low-cost timing source is required for non-critical frequency applications. The ceramic construction offers robustness compared to some other passive components, while the tight stability ensures reliable operation across the specified temperature range. Consider load capacitance requirements of the driving circuit to ensure proper oscillation start-up and sustained frequency accuracy.

Resonators Part Context

This part belongs to the ECS-CR2 series of chip-type SMD ceramic resonators from ECS Inc. International. The series is positioned as an economical alternative to quartz crystals for designs where high precision is not essential. The 'A' suffix typically denotes specific packaging or tape/reel configuration details consistent with the manufacturer's standard product coding for this family.

Resonators Replacement Considerations

Direct substitutes must match the 12 MHz frequency, SMD package dimensions, and ±0.3% stability. Verify equivalent ceramic resonator parts from other manufacturers that meet the same electrical specifications and thermal range. Ensure pinout compatibility if replacing in existing PCB layouts.
