Crystals Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm exact electrical parameters and packaging specifications. Ensure compatibility with reflow soldering profiles defined in the datasheet. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with assembly line processes.

Crystals Selection Notes

Select this component when a 20.48 MHz fundamental frequency with tight ±10ppm stability is required. The 18pF load capacitance must match the oscillator circuit design. Consider the 100 Ohms ESR limit for driver strength requirements. The compact 4-SMD footprint suits high-density PCB layouts requiring hermetic sealing.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. The series offers various frequencies within the 16–60MHz range with different tolerance options. The 402F20412IDR specifically addresses applications needing precise timing at 20.48 MHz in a small surface-mount form factor.

Crystals Replacement Considerations

Cross-reference with other 402 Series variants if frequency or tolerance differs. Verify pinout and mechanical dimensions match existing footprints before substitution.
