Crystals Procurement Notes

Verify the specific suffix 'CKR' against the manufacturer's current datasheet to confirm availability status and exact electrical tolerances. Ensure the target circuit design accommodates the specified 8pF load capacitance and 60 Ohm ESR requirements. Confirm that the operating environment remains within the -20°C to +70°C range to maintain frequency accuracy. Cross-reference the package dimensions with the PCB footprint library prior to implementation.

Crystals Selection Notes

Select this component when a 40.61 MHz fundamental frequency crystal is required for surface-mount assembly. The ±20 ppm tolerance makes it suitable for general-purpose timing applications where high precision is not critical. Consider the 8pF load capacitance requirement to ensure proper oscillator circuit tuning. The standard industrial temperature range fits most non-extreme environmental applications.

Crystals Part Context

This part belongs to the CTS 416 Series of miniature crystals. The series offers various frequencies and packages optimized for SMD manufacturing. The 416F406X3CKR specifically utilizes the 4-SMD No Lead form factor, common in modern electronics for automated placement. It serves as a passive frequency-determining element in resonant circuits.

Crystals Replacement Considerations

Direct substitutes include other 40.61 MHz crystals with matching 8pF load capacitance and similar physical dimensions. Verify that any replacement maintains the same ESR value and frequency stability specifications. Check for identical package outline drawings to ensure mechanical compatibility without PCB redesign.
