Resonators Procurement Notes

Verify the specific suffix G55001 against standard CERALOCK part numbering conventions to confirm the exact electrical characteristics and package variant. Ensure compatibility with the target application's load capacitance requirements before procurement. Cross-reference the manufacturer datasheet for detailed soldering profiles and handling instructions to maintain component integrity during assembly.

Resonators Selection Notes

Select this component when a stable 4.166 MHz reference is required with minimal external passive components. The ±0.2% tolerance suits applications demanding higher precision than standard ceramic resonators. Consider the 39 pF internal capacitance to match the microcontroller's specified load capacitance, eliminating the need for external capacitors and reducing board space.

Resonators Part Context

This part belongs to the CSTCR_G family of small-cap chip ceramic resonators. These devices combine piezoelectric resonance with integrated capacitors to offer a cost-effective alternative to crystal oscillators. The CERALOCK branding indicates Murata's proprietary technology for enhancing frequency stability and reducing electromagnetic interference in compact electronic designs.

Resonators Replacement Considerations

Direct substitutes within the same series include CSTCR4M16G55-R0, though tolerance differences may exist. Verify equivalent frequency, load capacitance, and physical dimensions before substitution.
