Crystals Procurement Notes

Verify the specific suffix 'IJT' against the manufacturer's current datasheet to confirm package and tape specifications. Check official distributor channels for availability as stock levels fluctuate. Ensure compatibility with existing PCB footprints and reflow soldering profiles before procurement.

Crystals Selection Notes

Select this component when a 30.72 MHz reference with tight ±10ppm tolerance is required. Compare ESR values against oscillator drive requirements. Validate that the 9pF load capacitance matches the circuit design. Consider thermal performance within the specified operating range.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. The series offers various frequencies and packages. The 402F30712IJT specifically targets applications needing high precision in a small SMD footprint, differentiating it from larger through-hole or lower-precision alternatives.

Crystals Replacement Considerations

Direct substitutes include 402F30712IAR and 402F30712IKR. Verify if differences in load capacitance (10pF vs 8pF) affect circuit performance. Parameter-equivalent parts may require impedance matching adjustments.
