Crystals Procurement Notes

Verify the exact suffix 'FE27' against official Suntsu datasheets to confirm the 200 Ohm ESR specification. Ensure compatibility with reflow soldering profiles specified in the manufacturer's handling guidelines. Cross-reference the 12pF load capacitance requirement with your circuit design to prevent frequency deviation during production.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency is required with tight ±10ppm tolerance. The 200 Ohm ESR limit dictates driver capability requirements. Compare the 4-SMD package dimensions against PCB space constraints. Verify that the operating temperature range meets system environmental specifications before finalizing the bill of materials.

Crystals Part Context

This part belongs to the SXT21412 series of surface mount crystals from Suntsu Electronics. The series offers various frequency options and package styles. The FE27 suffix typically denotes specific electrical characteristics including ESR and load capacitance values distinct from other variants in the same physical package family.

Crystals Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 12pF load capacitance, and 200 Ohm ESR. Verify pinout compatibility for the 4-SMD no lead package. Check if alternative manufacturers offer equivalent fundamental mode crystals with similar stability ratings.
