Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compliance with required frequency stability and temperature range specifications. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint design. Request updated documentation directly from Suntsu Electronics or authorized distributors to validate current manufacturing status and RoHS compliance before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±25 ppm tolerance is required for space-constrained designs. The 8 pF load capacitance must match the oscillator circuit requirements specified in the host device datasheet. Ensure the 60 Ohm ESR is compatible with the driving circuit's power constraints. Evaluate thermal performance characteristics if the application involves extreme environmental conditions beyond standard commercial ranges.

Crystals Part Context

This part belongs to the SAX214 series of ceramic surface-mount crystals from Suntsu Electronics. The series offers various frequencies and package options for general-purpose timing applications. The CY4B suffix typically denotes specific electrical characteristics within this product line, distinguishing it from other variants with different tolerances or load capacitances.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz SMD crystals with identical 8 pF load capacitance and similar ESR values. Verify pin compatibility and mechanical footprint alignment when considering alternative manufacturers. Cross-reference frequency stability requirements to ensure replacement parts meet or exceed the ±25 ppm specification.
