• Surface-mount packaging facilitates automated assembly processes
• Designed for high-frequency signal generation applications

Crystals Applications

• Microcontroller clock sources
• Communication interface timing
• Digital signal processing circuits

Crystals Procurement Notes

Verify the specific ESR value against the official datasheet, as some sources indicate variations between 30 Ω and 60 Ω. Confirm the package dimensions match the target PCB footprint. Ensure compliance with RoHS standards if required by the end product specifications. Cross-reference the manufacturer's latest documentation to confirm availability and exact electrical parameters before finalizing the bill of materials.

Crystals Selection Notes

Select this component when a 48 MHz reference signal is required with tight initial tolerance. The 8 pF load capacitance must align with the oscillator circuit design. Consider the 60 Ω ESR impact on start-up time and drive level sensitivity. The SMD form factor is ideal for space-constrained designs. Evaluate thermal performance within the operating temperature range to maintain frequency stability.

Crystals Part Context

This part belongs to the SCTF SX1B series of surface-mount crystals. It shares the standard 4-SMD footprint common to this family. The series offers various frequencies and tolerances. The SX1B designation indicates a specific size and pin configuration optimized for modern SMT production lines. It is distinct from through-hole or larger package variants.

Crystals Replacement Considerations

Direct substitutes include other 48 MHz crystals with identical 8 pF load capacitance and compatible ESR values. Verify that alternative parts meet the same ±10 ppm tolerance and ±30 ppm stability requirements. Ensure the replacement package matches the 4-SMD outline to avoid rework. Check for equivalent thermal and mechanical specifications.
