• Microcontroller timing circuits

Resonators Procurement Notes

Verify the specific suffix '51' indicates the 5 pF built-in capacitance variant, distinct from other series members like '53' which use 15 pF. Confirm RoHS compliance status via official documentation before finalizing procurement specifications.

Resonators Selection Notes

Select this part when a precise 20 MHz clock source is required with tight initial tolerance. The 5 pF internal capacitance suits MCU designs expecting this specific load value. Ensure the application environment remains within the specified -40°C to +125°C operational limits.

Resonators Part Context

This component belongs to the CSTNE_VH3C series of CERALOCK ceramic resonators. It serves as a cost-effective alternative to quartz crystals in automotive electronics where moderate frequency stability is sufficient. The series is optimized for high-volume SMT production processes.

Resonators Replacement Considerations

Direct substitutes include CSTNE20M0V53C000R0 (15 pF) if the circuit design allows for different load capacitance adjustments.
