Crystals Procurement Notes

Verify the specific suffix 'IDR' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the load capacitance requirement of the target circuit matches the component's 18pF rating. Confirm that the ±20ppm stability meets the system's jitter and accuracy requirements before finalizing procurement.

Crystals Selection Notes

Select this component when a small footprint 4-SMD crystal is required for 37.4 MHz applications. The 18pF load capacitance must align with the oscillator circuit design. Consider the 60 Ohm ESR for drive level sensitivity. Verify that the -40°C to +85°C temperature range covers the operational environment of the end product.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. These components are designed as general-purpose resonators for consumer and industrial electronics. The series offers various frequencies and packages, with the 402F37422IDR specifically providing a standard 37.4 MHz output in a miniaturized SMD form factor.

Crystals Replacement Considerations

Direct substitutes include other 37.4 MHz crystals with identical 18pF load capacitance and 4-SMD (1.6x1.2mm) packaging. Equivalent parts from other manufacturers must match the 60 Ohm ESR and ±20ppm stability to ensure circuit compatibility.
