Crystals Procurement Notes

Verify the specific suffix CB17 against project requirements to ensure compatibility with the intended load capacitance and temperature range. Confirm that the 40 Ohm series resistance meets the driving circuit specifications. Always consult the official manufacturer datasheet for final electrical characteristics and handling guidelines before integration into production designs.

Crystals Selection Notes

Select this component when a compact 40 MHz crystal is required for space-constrained PCB layouts. The ±25 ppm tolerance suits general-purpose digital systems where moderate frequency accuracy is sufficient. Ensure the application environment stays within the -10°C to +70°C operational limit to maintain specified stability levels during continuous operation.

Crystals Part Context

This part belongs to the SXT3248 series of ceramic crystals from Suntsu Electronics. The series offers various frequency options and tolerance grades tailored for different timing needs. The CB17 designation indicates specific electrical parameters including load capacitance and resistance values distinct from other variants in the same physical package family.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 3.2x2.5mm footprint, and 8pF load capacitance. Verify equivalent series resistance and temperature stability ratings. Cross-reference with manufacturer-approved replacement lists to ensure functional parity without redesigning the oscillator circuit.
