Crystals Procurement Notes

Verify the specific load capacitance and ESR requirements against the target circuit design to ensure optimal oscillation startup and stability. Confirm that the 4-SMD no-lead package dimensions align with the footprint specifications on the printed circuit board. Ensure compatibility with standard reflow soldering profiles recommended for lead-free surface-mount components to maintain device integrity during manufacturing.

Crystals Selection Notes

Select this component when a 48 MHz clock signal with ±10 ppm stability is required for digital logic or communication interfaces. The choice is appropriate for applications prioritizing small form factor integration via the SMD package. Consider the 10 pF load capacitance requirement for matching the oscillator circuit's stray capacitance. Evaluate the 30 Ohm ESR against the driving capability of the host microcontroller or oscillator IC to prevent under-driving or over-driving conditions.

Crystals Part Context

This part belongs to the SX3B series of quartz crystals from Shenzhen SCTF Electronics, designed for general-purpose timing applications. The series offers various frequencies and packages to support diverse consumer and industrial electronics needs. The SX3B48.000F1010F30 specifically targets the 48 MHz market segment, commonly used in USB interfaces and microcontroller clocks within portable and industrial hardware ecosystems.

Crystals Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 10 pF load capacitance, 30 Ohm ESR, and 4-SMD no-lead package outline. Verify that alternative manufacturers provide equivalent ±10 ppm stability and AT-cut construction. Cross-reference pin assignments and mechanical tolerances to ensure seamless interchangeability without redesigning the PCB layout.
