The 0900FM15D0039001E is a miniature impedance-matched ceramic filter designed for Semtech SX1261, SX1262, and LLCC68 transceivers. It operates within the 902 MHz to 928 MHz frequency range with an unbalanced configuration. The component features a center frequency of 866 MHz and a bandwidth of 8 MHz at a 50 Ohm impedance level. Packaged in an 0805 (2012 metric) surface-mount footprint, it serves as an EMI/RFI filter for high-frequency solutions.
Verify the legacy part number 0900FM15D0039 when sourcing replacements or reviewing older documentation. Confirm that the global manufacturing part number matches 0900FM15D0039001E to ensure correct specification alignment. Cross-reference datasheets for critical grounding via placement requirements to maintain intended harmonic attenuation performance.
Select this component specifically for designs utilizing Semtech SX1261, SX1262, or LLCC68 chips requiring pre-tuned filtering. The 50 Ohm impedance and 0805 package size must align with the PCB layout constraints. Ensure the application operates strictly within the 902-928 MHz range to utilize the specified 8 MHz bandwidth effectively.
This component belongs to Johanson Technology's family of impedance-matched ceramic filters. These passive components are engineered to simplify RF front-end design by integrating matching networks directly into the filter structure. The product line targets compact wireless devices requiring precise signal conditioning in the sub-GHz spectrum.
The legacy part number 0900FM15D0039 is confirmed as a direct predecessor. Substitutions should be verified against official Johanson Technology documentation to ensure identical electrical characteristics and mechanical dimensions.
