Crystals Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm exact electrical parameters such as tolerance and temperature range. Ensure the ordering part number matches the required load capacitance and ESR specifications for the target application circuit. Confirm compliance with RoHS directives and lead-free manufacturing standards before finalizing procurement orders.

Crystals Selection Notes

Select this component when a small form factor is critical alongside adequate EMI suppression capabilities. The four-terminal structure supports direct ground connection for improved signal integrity. Consider the ±50 ppm tolerance limit for system-level frequency budget calculations to ensure compatibility with receiver sensitivity requirements.

Crystals Part Context

This model belongs to the SXT224 series of industrial-grade crystals from Suntsu Electronics. The series utilizes a ceramic substrate and a four-pad configuration to address electromagnetic interference issues common in 2.4 GHz wireless applications. It serves as a timing reference solution for modern miniaturized electronics requiring robust performance across commercial and industrial environments.

Crystals Replacement Considerations

Direct substitutes include other SXT224 series variants with compatible pinouts and similar electrical characteristics. Verify that alternative models maintain the same 48 MHz frequency, 10 pF load capacitance, and 50 Ohm ESR to ensure circuit compatibility without redesigning the oscillator layout.

Crystals FAQ

What is the primary advantage of the four-pad design over standard two-pin crystals?

The four-pad design allows unused pins to be connected to the main ground plane, providing inherent shielding that reduces electromagnetic interference radiation by approximately 9 dB compared to two-pin components.

Does this crystal require external matching inductors?

No, the SXT22410AA16-48.000M uses an AT-cut fundamental frequency design, which simplifies the oscillation circuit and eliminates the need for additional matching inductors typically required for overtone modes.
