Procurement Notes

Verify current availability status as distribution channels may indicate discontinued or limited stock conditions. Confirm that the specific suffix 'C' aligns with required specifications, noting that manufacturer-recommended substitutes such as the PE64904D-Z exist. Ensure compliance with RoHS3 standards and check for any recent product change notices affecting the component's electrical characteristics or packaging before finalizing procurement orders.

Selection Notes

Select this component for applications requiring precise digital control over capacitance values in the UHF and SHF bands. The SPI interface allows for easy integration with microcontrollers or FPGAs. Consider the 2.6V DC voltage rating when designing power supply rails. The small 10-QFN footprint is suitable for space-constrained mobile and wireless devices. Evaluate thermal management requirements associated with the surface-mount package.
