Crystals Procurement Notes

Verify the specific ESR value against the official datasheet, as some listings indicate 60 Ohms while others specify 100 Ohms for similar variants. Confirm the active lifecycle status directly with Suntsu Electronics to ensure long-term availability. Cross-reference the package dimensions with your PCB footprint library to guarantee mechanical fit before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with moderate stability. The 17 pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR limit for drive level sensitivity. Ensure the operating environment stays within the specified -30°C to +85°C range to maintain the ±50 ppm tolerance specification without degradation.

Crystals Part Context

This part belongs to the SXT21417 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies tailored for digital timing applications. The AA16 suffix typically denotes specific physical dimensions and pin configurations common to this product line. These components are engineered for high-volume manufacturing environments requiring consistent electrical performance.

Crystals Replacement Considerations

Direct substitutes include other 37.4 MHz crystals with identical 17 pF load capacitance and compatible ESR values. Verify that replacement parts support the same 4-SMD no-lead package profile. Ensure alternative suppliers offer matching ±50 ppm tolerance and industrial temperature ratings to maintain system timing integrity.
