Procurement Notes

Verify manufacturer designation as TXC Corporation despite distributor branding. Confirm package dimensions match 2.5x2.0mm footprint requirements. Ensure load capacitance specifications align with circuit design parameters. Check availability status as distribution may vary by region. Validate datasheet version for accurate electrical characteristics prior to integration.

Selection Notes

Select this component when a 16.66667 MHz reference is required in space-constrained layouts. Consider the ±30 ppm stability sufficient for standard digital interfaces. Evaluate thermal requirements against the -40 to +85°C operational range. Compare physical size constraints against alternative packages within the same series. Verify compatibility with existing PCB soldering profiles for seam seal devices.
