Crystals Procurement Notes

Verify the specific suffix 'X-R' against official manufacturer documentation to confirm reel packaging and tape-and-reel specifications. Ensure compatibility with standard reflow soldering profiles defined in the datasheet. Confirm that the 4-pin SMD footprint matches the target PCB layout dimensions precisely. Validate RoHS compliance status through current certification records prior to integration.

Crystals Selection Notes

Select this component when a 27.12 MHz reference is required for space-constrained designs. The 4 pF load capacitance must match the oscillator circuit requirements. Consider the ±30 ppm tolerance for applications requiring moderate frequency accuracy. Evaluate the 100 Ohm series resistance against drive level constraints to prevent over-driving the crystal element during operation.

Crystals Part Context

This part belongs to the C1E series of thin film or bulk acoustic wave crystals designed for high-volume surface mount applications. The series offers various frequency options and package sizes. The C1E variant specifically targets cost-sensitive consumer electronics where small form factors are critical. It serves as a fundamental timing element in systems requiring precise clock synchronization.

Crystals Replacement Considerations

Cross-reference with other 27.12 MHz 4-SMD crystals having identical 4 pF load capacitance and similar dimensional constraints. Verify pinout compatibility and electrical parameters such as series resistance and stability before substitution. Ensure the replacement part meets the same thermal and mechanical stress requirements.
