Crystals Procurement Notes

Verify the specific suffix 'AA' corresponds to the required ±50 ppm tolerance and stability specifications. Confirm the package type matches the 4-SMD no-lead footprint dimensions. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the manufacturer's official datasheet for the complete electrical characteristics and handling instructions.

Crystals Selection Notes

Select this component when a small form factor is critical for the design. Choose this model if the application requires a 25 MHz reference with moderate precision. Consider the ESR value in relation to the oscillator circuit's drive level requirements. Evaluate the temperature stability against the operational environment constraints.

Crystals Part Context

This part belongs to the SXT214 series of ceramic SMT crystals. The series offers various frequency options and tolerance grades. The 4-SMD package provides a compact solution compared to larger through-hole or standard SMD crystals. The series is designed for high reliability in consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 18 pF load capacitance, and 4-SMD 2.0x1.6mm package. Verify that alternative components meet the same ±50 ppm stability and -40°C to +85°C temperature range. Check ESR compatibility to ensure proper circuit oscillation.
