Crystals Overview

The SXT83418CC38-29.4912M is a high-stability crystal oscillator manufactured by Suntsu Electronics, Inc., designed for precise timing applications. It operates at a nominal frequency of 29.4912 MHz with a frequency stability and tolerance of ±25ppm. The component features a load capacitance of 18pF and an equivalent series resistance (ESR) of 60 Ohms. It is housed in a 4-SOJ surface-mount package with a 5.50mm pitch, measuring 8.00mm x 3.80mm with a maximum height of 2.50mm. The device is RoHS compliant and lead-free.

Crystals Feature Summary

• High-stability performance suitable for precision timing requirements
• Surface-mount 4-SOJ package design for automated assembly
• RoHS compliant and lead-free construction

Crystals Applications

• Precision timing circuits
• Digital signal processing systems
• Communication equipment requiring stable clock sources

Crystals Procurement Notes

Verify the specific suffix CC38 to confirm the ±25ppm stability rating, as other suffixes like BB38 or AA27 indicate different stability levels such as ±30ppm or ±50ppm. Ensure the 4-SOJ package dimensions match the target PCB footprint. Confirm RoHS compliance status if required by environmental regulations. Check the active lifecycle status to ensure long-term availability for production.

Crystals Selection Notes

Select this component when a 29.4912 MHz frequency with ±25ppm stability is required. Compare against variants like SXT83418BB38-29.4912M if higher stability is not needed, or SXT83418AA27-30.000M for different frequencies. Consider the 18pF load capacitance compatibility with the host circuit's oscillator design. Evaluate the 60 Ohm ESR against the oscillator circuit's drive level specifications.

Crystals Part Context

This part belongs to the SXT83418 series of crystals from Suntsu Electronics, Inc. The series includes various frequency options and stability ratings, distinguished by alphanumeric suffixes. For example, the SXT83418CC17 variant shares the same package but may differ in stability. The CC38 suffix specifically denotes the 29.4912 MHz frequency with ±25ppm stability in the 4-SOJ form factor.

Crystals Replacement Considerations

Direct substitutes include SXT83418BB38-29.4912M for similar package and frequency but with ±30ppm stability. Other family members like SXT83418CC17-29.4912M share the package but require verification of stability differences. Cross-reference with other manufacturers' 29.4912 MHz crystals in 4-SOJ packages only if electrical parameters are identical.
