Resonators Procurement Notes

Verify that the specific suffix B in the part number corresponds to the required package or tape configuration as defined in the official datasheet. Confirm that the 15 pF load capacitance matches the target oscillator circuit requirements. Ensure compliance with RoHS standards if applicable to the final product regulations. Check the operating temperature range against environmental specifications.

Resonators Selection Notes

Select this component when a 7 MHz reference signal is required with tight frequency stability. The integrated load capacitance reduces external component count compared to standard crystals. Consider the 4.5 x 2 mm footprint for PCB layout constraints. Evaluate the -20°C to +80°C range against operational environments.

Resonators Part Context

This part belongs to the CSTCR series of ceramic resonators from Murata Electronics. These components are designed as cost-effective alternatives to quartz crystals in applications where moderate frequency stability is sufficient. The CERALOCK branding indicates proprietary packaging technology aimed at improving reliability during soldering processes.

Resonators Replacement Considerations

Cross-reference other parts within the CSTCR series for different frequencies or load capacitances. Verify mechanical compatibility with existing footprints before substituting.
