• Ceramic construction for robust frequency stability
• Surface-mount design for compact integration
• Standardized SMD footprint for automated placement

Crystals Applications

• General purpose clock generation circuits
• Microcontroller oscillator inputs
• Digital signal processing timing references

Crystals Procurement Notes

Verify the specific lot date code and manufacturing origin upon receipt to ensure compliance with project requirements. Confirm that the received components match the 4-SMD no-lead package specification. Check for any physical damage to the ceramic body or termination pads before soldering. Ensure storage conditions remain within recommended limits to preserve material integrity until use.

Crystals Selection Notes

Select this component when a 20 MHz reference is required with moderate stability needs. The 16 pF load capacitance must align with the target circuit's oscillator design parameters. Consider the 60 Ohm ESR limit for drive level sensitivity. This part is suitable for consumer electronics where cost-effective ceramic solutions are preferred over higher-stability quartz alternatives.

Crystals Part Context

Geyer Electronic America, Inc. manufactures frequency control devices including crystals and resonators. The 12.88669 belongs to their line of ceramic SMD crystals. These components serve as fundamental timing elements in electronic systems requiring precise frequency references without the complexity of active oscillators.

Crystals Replacement Considerations

Cross-reference with other 20 MHz ceramic SMD crystals having 16 pF load capacitance and similar ESR values. Verify pinout compatibility for the 4-SMD no-lead package before substitution.
