RF Directional Couplers Procurement Notes

Verify the specific suffix FLTR against official datasheets to confirm compatibility with required RoHS or lead-free standards, as product attributes may vary. Confirm that the 0402 package dimensions align with PCB layout constraints. Ensure the 3W power rating meets system requirements before integration. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

RF Directional Couplers Selection Notes

Select this component when a small footprint is critical for 2.4GHz ISM band applications. The 18dB coupling value suits scenarios requiring moderate signal sampling without significant main path loss. Consider the 0.35dB insertion loss impact on overall link budget. Verify that the -42dB isolation level provides sufficient separation between coupled and isolated ports for the specific circuit design.

RF Directional Couplers Part Context

This part belongs to the CP series of RF directional couplers from KYOCERA AVX. These components are designed for use in communication equipment where space-saving and reliable RF signal directionality are required. The series typically employs thin-film technology to achieve consistent performance across various frequency bands while maintaining a small physical profile suitable for modern consumer electronics.

RF Directional Couplers Replacement Considerations

Consult official substitution guides for equivalent thin-film couplers in the 0402 package with similar 18dB coupling and 2.4GHz operation. Verify pinout compatibility and thermal characteristics before swapping. Generic replacements may not match the specific isolation or return loss metrics provided by the original manufacturer.
