Crystals Procurement Notes

Verify the specific load capacitance requirement of your circuit against the 12pF specification to ensure accurate frequency performance. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet. Ensure that the operating temperature range meets the environmental conditions of the final application, as thermal variations can impact frequency stability beyond the stated ±10 ppm tolerance.

Crystals Selection Notes

Select this component when a 27 MHz reference is required in a space-constrained design. The 4-SMD form factor allows for automated placement, improving assembly efficiency compared to through-hole alternatives. Consider the 30 Ohm ESR value when designing the oscillator circuit to ensure sufficient drive level without overdriving the crystal. Verify compatibility with the target microcontroller or clock input interface specifications.

Crystals Part Context

This part belongs to the SX3B series of surface-mount crystals from Shenzhen SCTF Electronics. The series is characterized by AT-cut technology and ceramic packaging with metal shielding. Similar models in the lineup vary primarily by frequency and load capacitance values, such as the SX3B25.000F1210F30 or SX3B24.000F1210F30, which share identical physical dimensions and mounting characteristics but operate at different frequencies.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz crystals with identical 12pF load capacitance and 4-SMD no-lead footprints. Cross-reference pinout diagrams and mechanical dimensions to ensure board compatibility. Verify that alternative manufacturers meet the same ±10 ppm tolerance and 30 Ohm ESR requirements to maintain system timing integrity.
