• Communication interface circuits utilizing standard baud rate dividers
• Embedded system timing modules needing compact surface-mount solutions

Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu Electronics documentation to confirm exact temperature ranges and tolerance levels. Ensure that the 4-SMD no-lead package dimensions match your PCB footprint requirements. Cross-reference the ESR value of 200 Ohms with your circuit design specifications to guarantee proper oscillator startup conditions. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 18.432 MHz frequency is required for serial communication or microcontroller operations. The ±50 ppm tolerance suits general-purpose digital logic rather than high-precision RF applications. Consider the 17 pF load capacitance requirement to ensure accurate frequency matching with the host circuit. The commercial temperature range limits usage in extreme environmental conditions compared to extended grade alternatives.

Crystals Part Context

This part belongs to the SXT21417 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options and tolerance grades. The AA07 suffix typically denotes specific packaging and tolerance characteristics within this product line. These components are widely used in consumer electronics and industrial control systems where reliable timing is essential.

Crystals Replacement Considerations

Direct substitutes include other 18.432 MHz crystals with identical 17 pF load capacitance and similar ESR values. Verify pinout compatibility for the 4-SMD no-lead package. Check if alternative manufacturers offer comparable ±50 ppm tolerance within the same temperature range. Ensure any replacement maintains the fundamental frequency mode to avoid harmonic issues.
