Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging options and moisture sensitivity levels. Confirm that the selected variant meets all environmental compliance standards such as RoHS and REACH for your target market regulations before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 18.432 MHz reference is required with strict ±15ppm initial accuracy. Ensure the circuit design accounts for the 18pF load capacitance to maintain frequency accuracy. Verify that the 50 Ohm ESR aligns with the oscillator circuit's drive level limitations to prevent overdriving the crystal element.

Crystals Part Context

This part belongs to the 435 Series of surface-mount crystals from CTS-Frequency Controls. These components are engineered for general-purpose timing applications where space constraints necessitate small form factors. The series offers various frequency options within a standardized package profile to simplify supply chain management across different product lines.

Crystals Replacement Considerations

Direct substitutes include other 18.432 MHz SMD crystals with matching 18pF load capacitance and similar physical dimensions. Cross-reference package dimensions and mounting pad layouts to ensure mechanical compatibility during replacement or redesign phases.
