Procurement Notes

Verify the specific suffix against official Infineon documentation to confirm exact packaging and tape-and-reel specifications. Confirm availability status as distribution channels may list end-of-life or limited stock items. Ensure the ordering part number matches the required package variant and compliance certifications before finalizing procurement orders.

Selection Notes

Select this component when a low nominal capacitance around 5.3 pF is required for UHF applications. The common cathode dual-element design allows for differential tuning or balanced circuit topologies within a minimal footprint. Verify that the 6 V breakdown voltage aligns with the maximum reverse bias requirements of the target RF circuit design.
