Crystals Procurement Notes

Verify the specific suffix 'IK' against the manufacturer's current datasheet to confirm terminal configuration and plating specifications. Ensure the selected variant matches the required load capacitance and ESR parameters for the target circuit design before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 18.432 MHz reference is required with ±10 ppm accuracy. The 20 pF load capacitance must align with the host oscillator circuit requirements. Consider the 60 Ohm ESR limit to ensure proper oscillation startup conditions are met within the specified operating temperature range.

Crystals Part Context

This part belongs to the 7M series of seam-sealed crystals from TXC Corporation. These components utilize a hermetic sealing process to protect the quartz element, offering superior reliability compared to non-sealed alternatives in harsh environments while maintaining standard industry pinouts.

Crystals Replacement Considerations

Cross-reference with other 18.432 MHz crystals featuring 20 pF load capacitance and similar dimensions. Verify that substitute parts meet the same ±10 ppm tolerance and 60 Ohm ESR specifications to maintain circuit performance integrity.
