Crystals Procurement Notes

Verify the exact part number against official Suntsu Electronics documentation to ensure compatibility with design requirements. Confirm that the specified load capacitance and ESR values match the circuit design specifications. Check the operating temperature range to ensure suitability for the intended application environment. Request detailed datasheets from authorized distributors to validate manufacturing standards and quality certifications before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 37.4 MHz frequency is required with moderate stability. Ensure the circuit design accommodates the 20 pF load capacitance and 40 Ohm ESR characteristics. Consider the 0°C to +70°C operating range for environmental constraints. Evaluate the 4-SMD package dimensions for space limitations on the printed circuit board. Compare against alternative frequencies if system requirements allow flexibility.

Crystals Part Context

This model belongs to the SXT32420 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options within a standardized package format. The AA07 suffix typically denotes specific packaging or handling characteristics within the product line. This particular variant focuses on the 37.4 MHz frequency point, serving niche timing applications requiring this specific harmonic or sub-harmonic relationship.

Crystals Replacement Considerations

Direct substitutes must match the 37.4 MHz frequency, 20 pF load capacitance, and 4-SMD no-lead package. Verify ESR compatibility to prevent oscillation startup issues. Ensure the replacement component meets the same ±50 ppm tolerance and temperature range specifications. Cross-reference pinout and footprint dimensions to guarantee mechanical fit without redesigning the PCB layout.
