Crystals Procurement Notes

Verify the specific suffix 'IAR' against the manufacturer's official datasheet to confirm exact load capacitance and temperature range specifications. Ensure compatibility with existing PCB footprint dimensions of 1.60mm x 1.20mm. Confirm that the 60 Ohm ESR aligns with the oscillator circuit requirements. Check current availability status as supply conditions may vary.

Crystals Selection Notes

Select this component when a 37.4 MHz reference is required in a small form factor. The 10pF load capacitance must match the host circuit's design. Consider the ±20ppm stability for applications requiring moderate precision. The 4-SMD package facilitates automated assembly. Verify thermal performance if operating near the upper temperature limits.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series offers various frequencies and packages for standard timing needs. The 402 series is characterized by its low profile and reliability for consumer and industrial electronics. It serves as a fundamental resonator for generating stable clock signals in digital systems.

Crystals Replacement Considerations

Direct substitutes include other 37.4 MHz crystals from CTS with identical 4-SMD packaging and 10pF load capacitance. Verify that alternative parts maintain the same 60 Ohm ESR and ±20ppm stability. Ensure the replacement supports the required operating temperature range and RoHS compliance.
