Crystals Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official datasheet to confirm the exact tolerance and packaging specifications, as suffixes can denote variations in frequency accuracy or reel configuration. Ensure compatibility with the target load capacitance of 9pF in the circuit design. Confirm that the 4-SMD footprint matches the PCB land pattern requirements for proper soldering and mechanical stability.

Crystals Selection Notes

Select this component when a stable 37.4 MHz reference is required with tight ±10 ppm tolerance. The low ESR of 60 Ohms suits modern low-power oscillator circuits. The wide temperature range makes it suitable for industrial or automotive-grade applications where environmental stability is critical compared to standard commercial grade parts.

Crystals Part Context

This part belongs to the CTS 402 Series, which covers a frequency range from 16 MHz to 60 MHz. The series is characterized by small form factors and high reliability for SMD applications. The 402F3741XIJR specifically targets the higher end of this range, offering a balance between size constraints and frequency precision for embedded systems.

Crystals Replacement Considerations

Direct substitutes include other 37.4 MHz crystals with 9pF load capacitance and similar SMD footprints, such as the 402F37422IJR if a ±20ppm tolerance is acceptable. Verify pinout and electrical parameters before substitution to ensure circuit compatibility.
