Crystals Procurement Notes

Verify the specific suffix 'CKR' against official CTS documentation to confirm the 8pF load capacitance specification, as suffix variations within the 402 series may indicate different electrical parameters or packaging types. Ensure compatibility with the target circuit's load capacitance requirements before integration.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency with ±10ppm stability is required in a compact 2.0x1.6mm footprint. Consider the 60 Ohm ESR and 8pF load capacitance for proper oscillator circuit design. Verify that the -20°C to +70°C temperature range meets the application's environmental constraints.

Crystals Part Context

This part belongs to the CTS 402 Series of MHz crystals, designed for surface-mount applications. The series offers various frequencies and load capacitances in standardized small outlines. The 402F37411CKR specifically targets applications requiring precise timing at 37.4 MHz with moderate stability requirements.

Crystals Replacement Considerations

Direct substitutes include other 402 series parts with identical 37.4 MHz frequency, 8pF load capacitance, and 4-SMD dimensions. Verify ESR and stability specifications match the original design requirements.
