Resonators Procurement Notes

Verify the specific suffix 'A' against project requirements, as it denotes the automotive grade variant. Confirm that the 33 pF internal capacitance aligns with the target microcontroller's external load specifications. Ensure the 40 Ohm impedance characteristic fits the oscillator circuit design. Validate that the -40°C to +125°C temperature range covers the intended operational environment without requiring derating.

Resonators Selection Notes

Select this component when automotive certification is mandatory for clock generation. The integrated capacitance reduces component count compared to discrete crystal solutions. Consider the 8 MHz frequency if lower speed processing or specific baud rate generation is required. The wide temperature range supports harsh automotive environments where standard commercial parts might fail.

Resonators Part Context

This part belongs to Murata's CERALOCK CSTNE series, specifically engineered for high-reliability automotive electronics. It serves as a cost-effective alternative to quartz crystals while providing necessary stability for digital logic timing. The series is designed to meet stringent automotive quality standards.

Resonators Replacement Considerations

Direct substitutes must be AEC-Q200 qualified ceramic resonators with 8 MHz frequency, 33 pF capacitance, and similar impedance characteristics. Verify package dimensions match the 3.2x1.3mm footprint. Check if alternative brands offer equivalent automotive grade certifications and temperature ranges.
