Resonators Procurement Notes

Verify the specific suffix B against the manufacturer's current datasheet to confirm exact tolerance and capacitance values. Ensure the PCB footprint matches the 7.20mm x 3.00mm dimensions. Confirm that the application environment remains within the specified -20°C to +80°C operating range to maintain frequency stability.

Resonators Selection Notes

Select this component when a cost-effective alternative to quartz crystals is required for commercial grade applications. The integrated capacitor reduces external component count. Verify that the ±0.3% stability meets system timing requirements. Consider the non-standard package size during layout planning.

Resonators Part Context

This part belongs to the ECS CR2 series of ceramic resonators. These components are commonly used as low-cost clock sources in consumer electronics. The series offers various frequencies and package options. The CR2 series is characterized by its built-in capacitor feature, which distinguishes it from standard crystal oscillators.

Resonators Replacement Considerations

Compatible substitutes include other 12 MHz ceramic resonators with similar 30 pF load capacitance and surface mount packages. Verify that replacement parts meet the same ±0.3% stability and -20°C to +80°C temperature specifications.
