Crystals Procurement Notes

Verify the specific suffix ATT against official CTS documentation to confirm package type and loading conditions. Ensure compatibility with reflow soldering profiles specified in the datasheet. Cross-reference part numbers carefully as minor suffix variations may indicate different electrical parameters or packaging formats. Confirm RoHS status through current manufacturer declarations rather than distributor summaries.

Crystals Selection Notes

Select this component when a 40.61 MHz fundamental frequency is required with ±20 ppm stability. The 6 pF load capacitance must match the oscillator circuit requirements. Consider the 60 Ohm ESR limit for drive level sensitivity. Evaluate the 4-SMD footprint against PCB layout constraints. Verify thermal performance within the operating temperature range defined in the official specification sheet.

Crystals Part Context

This crystal belongs to the CTS 416F series of surface-mount resonators. The series offers various frequency options and load capacitance configurations. The 416F40622ATT specifically addresses applications requiring precise timing at approximately 40.61 MHz. It serves as a passive frequency-determining element in oscillator circuits.

Crystals Replacement Considerations

Direct substitutes include other 40.61 MHz crystals with matching 6 pF load capacitance and similar ESR values. Compatible alternatives from other manufacturers must meet the same mechanical dimensions and electrical specifications. Verify that any replacement maintains the ±20 ppm tolerance requirement for the target application.
