Crystals Procurement Notes

Verify the specific suffix 'B' against official CTS documentation to confirm exact specifications, as suffixes often denote variations in tolerance or packaging. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing process before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with ±20 ppm tolerance is required in a compact 5.0x3.2mm footprint. Ensure the circuit design supports an 18 pF load capacitance and can accommodate a 40 Ohm ESR. Verify that the operating temperature range meets the application's thermal environment constraints.

Crystals Part Context

This part belongs to the CTS 445 Series of glass-seal crystals, designed for general-purpose timing applications. The series offers various frequencies and packages, providing designers with options for different size and performance requirements while maintaining consistent reliability standards across the product line.

Crystals Replacement Considerations

Direct substitutes include 445I25B25M00000 from CTS-Frequency Controls. Cross-brand replacements must match the 25 MHz frequency, 18 pF load capacitance, 2-SMD package dimensions, and similar electrical parameters to ensure functional compatibility.
