• Consumer electronics control units

Resonators Procurement Notes

Verify the specific suffix G53 against the official Murata datasheet to confirm the exact frequency tolerance and temperature range specifications. Ensure that the required operating environment aligns with the -40°C to +125°C rating. Confirm compliance requirements such as RoHS status prior to final integration into the production line.

Resonators Selection Notes

Select this component when a precise 6.25 MHz reference is required with tight tolerance constraints. Consider the wider temperature range compared to standard commercial grade variants. Evaluate the 15 pF internal capacitance against the microcontroller input capacitance to ensure proper oscillation startup conditions without additional external loading.

Resonators Part Context

This part belongs to the CSTCR-G series of CERALOCK ceramic resonators. It represents a specialized variant within Murata's portfolio designed for applications requiring higher temperature resilience than standard commercial parts. The series is characterized by its monolithic construction and built-in capacitor functionality.

Resonators Replacement Considerations

Direct substitutes include other Murata CSTCR models with identical 6.25 MHz frequency and 15 pF load capacitance, provided they match the 4.5 x 2.0 mm footprint and SMD termination style. Cross-vendor replacements require verification of equivalent impedance and physical dimensions.
