Crystals Procurement Notes

Verify the manufacturer designation as Shenzhen SCTF Electronics or Starcom Time Frequency when sourcing. Confirm the specific package type HC-49S-SMD matches the PCB footprint requirements. Ensure the load capacitance specification of 20pF aligns with the circuit design parameters before procurement.

Crystals Selection Notes

Select this component for applications requiring a stable 25 MHz reference signal in space-constrained designs. The HC-49S-SMD package offers a balance between electrical performance and board space efficiency. Consider the ±20 ppm tolerance for general timing applications where high-precision frequency stability is not critical.

Crystals Part Context

This part belongs to the SXMH series of surface-mount crystals from Shenzhen SCTF Electronics. The series provides various frequency options in the HC-49S-SMD format. Similar models include the SXMH30.000F2020F30, which offers a 30 MHz output in the same physical package, allowing for design flexibility within the same product family.

Crystals Replacement Considerations

Cross-reference tools indicate parametrically similar parts are available. Verify that any substitute maintains the 25 MHz frequency, 20pF load capacitance, and HC-49S-SMD package dimensions to ensure mechanical and electrical compatibility.
