Crystals Procurement Notes

Verify the manufacturer designation as Shenzhen SCTF Electronics when sourcing this component. Confirm that the part number matches the specific suffix G30 to ensure correct packaging and lead-free specifications. Cross-reference the load capacitance of 10 pF and ESR of 30 Ohms against your circuit design requirements to guarantee proper oscillator tank compatibility. Ensure the SMD3225-4P footprint aligns with your PCB layout constraints before finalizing procurement orders.

Crystals Selection Notes

Select this resonator when a 20 MHz reference with ±10 ppm stability is required in a compact surface-mount format. The 10 pF load capacitance must match the external capacitors specified in the host oscillator circuit design. Consider the 30 Ohm ESR limit to ensure sufficient drive level margin within the application. The SMD3225-4P package size offers a balance between thermal performance and board space efficiency for dense layouts.

Crystals Part Context

This component belongs to the SX3B series of passive crystal resonators from Shenzhen SCTF Electronics. The series typically covers various standard frequencies for general-purpose timing applications. The model designation indicates a 20 MHz unit with specific electrical parameters tailored for standard microcontroller or logic interface clocks. It represents a standard off-the-shelf solution for basic clock generation needs.

Crystals Replacement Considerations

Direct substitutes must maintain the 20 MHz frequency, 10 pF load capacitance, and 30 Ohm ESR. Compatible packages include SMD3225-4P or equivalent 3225 footprint variants from other manufacturers. Verify that alternative parts support the same ±10 ppm tolerance and operate within the required temperature range. Ensure the replacement uses AT-cut technology for similar frequency-temperature characteristics.
