Crystals Procurement Notes

Verify the specific part number against official Suntsu documentation to confirm electrical parameters. Ensure compatibility with the target load capacitance of 8 pF. Confirm that the ±50 ppm tolerance meets the system's timing requirements. Check for RoHS compliance if required by the manufacturing process. Validate the package type matches the PCB layout constraints.

Crystals Selection Notes

Select this component when a small form factor is critical for the design. The 8 pF load capacitance requires matching the oscillator circuit accordingly. Consider the ±50 ppm tolerance limit for frequency accuracy needs. Evaluate the 80 Ohm ESR against the driver strength capabilities of the host microcontroller or clock generator.

Crystals Part Context

This model belongs to the SAX214 series of ceramic crystals from Suntsu Electronics. The series is characterized by its small 2.0 x 1.6 mm size and 4-pad SMD configuration. These components are designed for high-volume consumer electronics where board space is limited. The series offers various frequency and tolerance options to suit different timing applications.

Crystals Replacement Considerations

Direct substitutes include other 2.0 x 1.6 mm 4-SMD crystals with 25 MHz frequency and 8 pF load capacitance. Verify pinout compatibility and ESR specifications before substitution. Cross-reference with Suntsu's updated catalog for newer revisions.
