Crystals Procurement Notes

Verify the manufacturer part number against official datasheets to confirm specifications. Ensure the package type matches the design requirements. Check for any specific handling instructions regarding electrostatic discharge during storage and installation.

Crystals Selection Notes

Select this component when a 20 MHz reference is required in a space-constrained design. Consider the ±20 ppm tolerance for system accuracy needs. Verify that the HC-49SMD package dimensions fit the available board area and soldering profile.

Crystals Part Context

This model belongs to the SXMH series of surface-mount quartz crystals from SCTF. These components are designed for general-purpose timing applications where moderate stability and small size are prioritized over high-precision performance found in oven-controlled or temperature-compensated variants.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz SMD crystals with identical electrical parameters and package dimensions. Cross-reference with equivalent parts from other manufacturers ensuring matching load capacitance and series resistance values.
