The component features a frequency tolerance of ±25ppm and a frequency stability of ±50ppm. It is housed in a compact 4-SMD, No Lead package measuring 2.50mm x 2.00mm (0.098" L x 0.079" W). The device is RoHS compliant and designed for precision timing applications requiring stable oscillation within standard operating conditions.

Crystals Feature Summary

• Precision frequency generation at 27.12 MHz with tight tolerance specifications
• Compact surface-mount design suitable for space-constrained PCB layouts
• RoHS compliant construction for environmental safety standards

Crystals Applications

• Precision timing circuits requiring stable clock signals
• Electronic devices utilizing 27.12 MHz reference frequencies
• Consumer electronics with surface-mount assembly requirements

Crystals Procurement Notes

Verify the specific lot code and manufacturing date against project requirements before procurement. Ensure that the 8pF load capacitance matches the oscillator circuit design to maintain the specified ±25ppm tolerance. Confirm RoHS compliance documentation is available for regulatory adherence. Check for any specific handling instructions regarding the 4-SMD no-lead package during soldering processes to prevent mechanical stress or cracking.

Crystals Selection Notes

Select this component when a 27.12 MHz crystal with ±25ppm initial tolerance and ±50ppm total stability is required. The 8pF load capacitance must align with the host oscillator's internal capacitors. Consider the 2.50mm x 2.00mm footprint for board space limitations. This part is suitable for applications where moderate stability suffices and cost-effective surface-mount integration is prioritized over higher-grade automotive or industrial temperature ranges.

Crystals Part Context

This model belongs to the SXT2248 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options and package sizes. The CA38 suffix typically denotes specific electrical characteristics and packaging variations within the product line. These components are general-purpose crystals intended for commercial electronic applications rather than specialized high-reliability sectors.

Crystals Replacement Considerations

Direct substitutes include other 27.12 MHz crystals with identical 8pF load capacitance and similar ±25ppm/±50ppm stability ratings. Verify that alternative parts match the 2.50mm x 2.00mm footprint and 4-pad configuration. Ensure replacement components maintain RoHS compliance and compatible ESR values around 80 Ohms to preserve circuit performance.
