Crystals Procurement Notes

Verify the specific suffix codes against the official CTS datasheet to ensure exact electrical parameters match the design requirements. Confirm that the 4-SMD footprint aligns with the PCB layout constraints. Check for any recent product change notifications regarding marking or material composition updates from the manufacturer.

Crystals Selection Notes

Select this component when a standard 25 MHz reference is required in a space-constrained surface mount application. Ensure the circuit load capacitance matches the specified 20 pF to maintain accuracy. Consider the ±30 ppm tolerance for applications requiring moderate frequency precision without active compensation.

Crystals Part Context

This part belongs to the 403 Series of SMD crystals from CTS-Frequency Controls. The series provides various frequencies in a standardized 3.2mm x 2.5mm footprint, offering a balance between size and performance for consumer electronics and industrial control systems requiring reliable timing sources.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz crystals in the same 4-SMD (3.2x2.5) package with matching 20pF load capacitance and similar ESR values. Verify pin compatibility and thermal characteristics before swapping.
