Crystals Procurement Notes

Verify the manufacturer part number against official SCTF documentation to ensure authenticity. Confirm that the specific ordering suffix matches the required load capacitance and frequency tolerance specifications for your circuit design. Request detailed datasheets from authorized distributors to validate electrical parameters before integration into production schedules.

Crystals Selection Notes

Select this component when a 20 MHz reference is required with 12 pF load capacitance compatibility. Ensure the target application supports the specified ESR value of 60 ohms for proper oscillator circuit startup. Verify that the PCB layout accommodates the specific footprint dimensions of the no-lead SMD package to maintain mechanical reliability during thermal cycling.

Crystals Part Context

This model belongs to the SX1B series of surface-mount crystals from Shenzhen SCTF Electronics. The series offers various frequencies and package sizes for general-purpose timing applications. The SX1B20.000F1210F30 specifically addresses the common 20 MHz requirement found in many embedded systems and consumer electronics devices.

Crystals Replacement Considerations

Cross-reference tools indicate parametrically similar parts are available. Verify that any substitute maintains identical 20 MHz frequency, 12 pF load capacitance, and compatible ESR values to ensure circuit compatibility.
