Crystals Procurement Notes

Verify the specific suffix 'M' against the manufacturer's official datasheet to confirm lead-free status and tape/reel packaging configuration. Ensure the 40 Ohm ESR specification matches the target circuit design requirements. Cross-reference the 37.4 MHz frequency with system clock inputs to prevent harmonic interference. Confirm RoHS compliance documentation is available from the authorized distributor prior to final procurement approval.

Crystals Selection Notes

Select this component when a 37.4 MHz reference is required in a 3.2mm x 2.5mm footprint. The ±20 ppm tolerance suits applications needing moderate stability without expensive oven-controlled oscillators. The 12 pF load capacitance must align with the host oscillator circuit's input capacitance. Consider the 40 Ohm ESR limit to ensure adequate drive level margins in the resonant circuit design.

Crystals Part Context

This part belongs to the SXT32412DA17 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies while maintaining consistent physical dimensions and electrical characteristics. It serves as a cost-effective alternative to larger through-hole crystals in space-constrained modern PCB layouts. The standardized package facilitates high-volume manufacturing processes.

Crystals Replacement Considerations

Direct substitutes must match the 37.4 MHz frequency, 12 pF load capacitance, and 4-SMD 3.2x2.5mm package. Verify that replacement parts support the same ±20 ppm tolerance and 40 Ohm ESR. Check compatibility with the -10°C to +70°C operating range. Ensure the replacement maintains RoHS compliance if environmental regulations apply.
