Crystals Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Ensure that the 4-SMD no-lead package dimensions align with your PCB footprint specifications. Confirm that the ±50 ppm stability meets the system's timing accuracy needs. Request the official datasheet from Suntsu Electronics to validate electrical parameters and handling instructions.

Crystals Selection Notes

Select this component when a 27 MHz frequency is required with moderate stability. The 18 pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR limit for drive level sensitivity. The surface-mount format is ideal for high-volume manufacturing. Evaluate thermal performance if operating near extreme temperature limits.

Crystals Part Context

This part belongs to Suntsu Electronics' SXT series of surface-mount crystals. The series offers various frequencies and packages for different timing applications. The SXT21418AA48 variant specifically denotes the package style and pin configuration. These components are commonly used in consumer electronics and industrial control systems where reliable timing is essential.

Crystals Replacement Considerations

Direct replacements must match the 27 MHz frequency, 18 pF load capacitance, and 4-SMD package. Verify compatibility with existing oscillator circuits. Check if alternative manufacturers offer equivalent stability and ESR specifications. Ensure the replacement part supports the same operating temperature range.
