Crystals Procurement Notes

Verify the specific suffix 'IAR' against the manufacturer's current datasheet to confirm package and loading specifications. Ensure that the 10pF load capacitance requirement matches the target circuit design before procurement. Check for updated availability status as distribution channels may vary.

Crystals Selection Notes

Select this component when a 48 MHz fundamental frequency with tight ±10ppm tolerance is required. The 10pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the 60 Ohm ESR limit for drive level sensitivity and power consumption constraints in the application.

Crystals Part Context

This part belongs to the CTS 402 series of MHz crystals. It shares the same physical footprint and electrical characteristics as other variants in the series, differing primarily in frequency and load capacitance parameters. It is intended for high-reliability consumer and industrial electronics requiring stable clock signals.

Crystals Replacement Considerations

Direct substitutes include parts with identical 48 MHz frequency, 10pF load capacitance, and 4-SMD(1.6x1.2) package. Verify ESR and tolerance match to ensure circuit compatibility without redesign.
