Crystals Procurement Notes

Verify the specific operating temperature range and aging specifications against the official datasheet prior to procurement. Confirm that the 4-SMD footprint matches the target PCB design constraints. Ensure compliance with RoHS directives if required by the end-product regulations. Cross-reference the manufacturer part number to avoid confusion with similar MEMS oscillator variants from the same supplier.

Crystals Selection Notes

Select this component when a fundamental mode quartz crystal is preferred over MEMS alternatives for lower phase noise characteristics. Consider the 10 pF load capacitance requirement to ensure proper circuit matching. Evaluate the 60 Ohm ESR against the oscillator driver strength to prevent over-driving. Assess the physical dimensions against available board real estate compared to larger through-hole options.

Crystals Part Context

This part belongs to the TXC Corporation line of ultra-miniature MHz crystals. These components are characterized by thin profiles and low series resistance. They are engineered for applications demanding high accuracy and extremely low aging rates. The product family supports various standard frequencies within the MHz range using standardized SMD packages.

Crystals Replacement Considerations

Direct substitutes include other 37.5 MHz quartz crystals with identical 10 pF load capacitance and compatible 4-SMD footprints. Verify that replacement parts maintain the ±20 ppm stability and 60 Ohm ESR limits. Ensure the alternative component supports the same operating temperature range as defined in the original specification.
