Crystals Procurement Notes

Verify exact electrical parameters against the manufacturer datasheet before integration, as specifications may vary by revision. Confirm package dimensions and soldering profiles align with PCB layout requirements. Check current availability status through authorized distributors, as lead times and stock levels fluctuate. Ensure compliance with project-specific environmental regulations such as RoHS3 and REACH restrictions prior to final procurement decisions.

Crystals Selection Notes

Select this component when a 36 MHz fundamental frequency with 8 pF load capacitance is required. Consider the 60 Ohm ESR value for oscillator circuit stability calculations. The 402 series offers a balance of size and performance suitable for space-constrained designs. Verify that the ±10 ppm tolerance meets system accuracy requirements compared to higher precision alternatives.

Crystals Part Context

The 402 series represents a standard line of surface-mount crystals from CTS-Frequency Controls, covering frequencies typically between 16 MHz and 60 MHz. These components utilize seam-welded technology for consistent performance. The 402F36022IKR specifically targets applications needing reliable timing at 36 MHz within a small form factor, serving as a common choice for embedded systems requiring precise clock signals.

Crystals Replacement Considerations

Direct substitutes include 402F36022IAR and 402F36022IJT from the same manufacturer, which share identical electrical characteristics but differ in packaging or reel configuration. Cross-manufacturer replacements must match the 36 MHz frequency, 8 pF load capacitance, and 4-SMD package dimensions to ensure mechanical and electrical compatibility.
