Crystals Procurement Notes

Verify that the ordered component matches the specific Shenzhen SCTF Electronics part number SX3B8.000F1210F30. Confirm the package type is 4-SMD, No Lead and the frequency is exactly 8 MHz. Ensure the supplier provides documentation confirming the ±10 ppm tolerance and 12 pF load capacitance specifications. Check for RoHS compliance status if required by project standards. Validate the operating temperature range covers the intended application environment.

Crystals Selection Notes

Select this component when an 8 MHz reference is required for surface mount designs. The 12 pF load capacitance must match the oscillator circuit design parameters. Consider the 300 Ohm ESR value for drive level compatibility. The industrial temperature range supports operation in harsh environments. Ensure the footprint matches the PCB layout for the 3.2 x 2.5 mm package.

Crystals Part Context

This crystal resonator belongs to the family of passive components used for frequency control in electronic systems. It serves as a critical timing element for microcontrollers and communication interfaces. The SMD format allows for automated assembly processes. It replaces through-hole variants where space constraints exist. The parallel mode operation distinguishes it from series resonant types.
