Crystals Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to ensure compatibility with specific load capacitance requirements. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Check RoHS compliance status if environmental regulations apply to the end product. Ensure storage conditions maintain moisture sensitivity level integrity prior to reflow soldering.

Crystals Selection Notes

Select this component when a 26 MHz reference with tight ±15 ppm stability is required in a small surface-mount footprint. The 12 pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR value for drive level constraints. Verify thermal performance meets the -20°C to +70°C operating range for the intended environment.

Crystals Part Context

This part belongs to the CTS 402 Series, which offers various surface-mount crystals optimized for space-constrained designs. The series provides options across different frequencies and packages, maintaining consistent electrical characteristics for standard timing needs. The 402F260XXCLR specifically addresses the demand for stable 26 MHz signals in modern compact electronics.

Crystals Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 12 pF load capacitance, ±15 ppm stability, and 4-SMD 2x1.6mm package. Verify ESR compatibility and mounting height restrictions. Cross-reference with other manufacturers' 402-style or equivalent SMD crystal offerings ensuring identical electrical parameters.
