Crystals Procurement Notes

Verify the specific suffix 'CLR' against official CTS documentation to confirm the exact load capacitance and packaging configuration, as suffixes often denote critical variations. Ensure the intended application environment remains within the specified -20°C to +70°C operational limits. Confirm that the 8 pF load capacitance matches the oscillator circuit design requirements to prevent frequency deviation. Check current availability status through authorized distributors, as supply levels may fluctuate.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental crystal with ±10 ppm stability is required for space-constrained designs. The 4-SMD No Lead package offers a small footprint of 2.00 mm x 1.60 mm, ideal for dense PCB layouts. Consider the 100 Ohm ESR limit when designing the oscillator circuit to ensure reliable startup. Verify compatibility with the target system's load capacitance requirements before finalizing the selection.

Crystals Part Context

The 402F37411CLR belongs to the CTS 402 Series of MHz crystals, which are characterized by their small surface-mount form factor. This series is engineered for high-volume manufacturing processes, utilizing standard reflow soldering profiles. The 402 Series generally targets cost-sensitive applications where moderate stability and compact size are prioritized over ultra-high precision or extended industrial temperature ranges.

Crystals Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include 402F37411CDR and 402F37411CKT from CTS-Frequency Controls. These alternatives share similar electrical characteristics and package dimensions. Verify that any substitute maintains the same 8 pF load capacitance and ±10 ppm tolerance to ensure circuit compatibility.
