Crystals Procurement Notes

Verify the specific suffix 'IAT' against official CTS documentation to confirm the exact load capacitance and temperature grade, as variations exist within the 402 series. Ensure compatibility with reflow soldering profiles specified in the datasheet. Confirm RoHS compliance status for current production batches.

Crystals Selection Notes

Select this component when a 48 MHz reference is required with ±20ppm stability. The 10pF load capacitance must match the circuit design requirements. Consider the 60 Ohm ESR for oscillator circuit tuning. The wide temperature range suits industrial environments compared to commercial grade alternatives.

Crystals Part Context

This part belongs to the CTS 402 series of thin-film crystals. The series offers various frequencies and package sizes. The 402F48022IAT specifically targets applications requiring stable timing in compact surface-mount designs.
