Crystals Procurement Notes

Verify that the specific ordering suffix matches the required frequency and tolerance specifications. Confirm the package type aligns with the PCB footprint requirements. Ensure compliance with environmental regulations such as RoHS if applicable to the final product. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability and authenticity before placing orders.

Crystals Selection Notes

Select this component when a precise 14.7456 MHz reference is required for surface mount designs. Consider the 70 Ohm ESR and 20 pF load capacitance to ensure compatibility with the oscillator circuit topology. Evaluate the ±30 ppm tolerance against the system's frequency accuracy requirements. Verify that the operating temperature range meets the environmental conditions of the intended application.

Crystals Part Context

This part belongs to the CSM1 series of low-profile surface mount crystals from Cardinal Components. The series offers various frequencies and packages optimized for modern electronics manufacturing.
