Crystals Procurement Notes

Verify the specific suffix CA4B against the manufacturer's official datasheet to confirm pinout and mechanical dimensions. Ensure the 25.000 MHz frequency matches system requirements. Cross-reference the 12 pF load capacitance with the host circuit design. Confirm the ±25 ppm tolerance meets application stability needs before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 25 MHz surface-mount crystal is required with moderate frequency stability. The 12 pF load capacitance must align with the oscillator circuit design. Consider the 80 Ohm ESR for drive level sensitivity. The no-lead package suits high-volume automated assembly lines requiring compact footprints.

Crystals Part Context

This part belongs to Suntsu Electronics' SMD crystal lineup. It shares the SAX21412 series form factor with other frequencies. The CA4B suffix denotes specific packaging and termination characteristics within the product family. It serves as a frequency reference element in electronic assemblies requiring precise timing signals.

Crystals Replacement Considerations

Direct replacements require matching 25 MHz frequency, 12 pF load capacitance, and 4-SMD no-lead package. Verify ESR compatibility with the driving circuit. Check if alternative manufacturers offer identical electrical parameters and mechanical dimensions for seamless substitution.
