Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the surface mount package dimensions match your PCB footprint requirements. Ensure that the operating environment remains within the specified -55 C to +125 C temperature range to maintain performance specifications and reliability standards.

Selection Notes

Select this component when a 28.0 GHz bandpass filter with 50 Ohm impedance is required for surface mount applications. Consider the 3.25 dB insertion loss specification in relation to system power budget constraints. Verify compatibility with high-temperature environments up to +125 C. Ensure the design accommodates the specific physical dimensions and soldering profiles associated with this surface mount package type.

Part Context

This part is part of the Knowles Dielectric Labs Bandpass series, focusing on signal conditioning components. It is distinct from other models like B012MD5S-T which operate at lower frequencies such as 1.227 GHz. The B274MB1S-T is specifically engineered for millimeter-wave applications, differentiating it from general-purpose ceramic capacitors or lower-frequency filters within the same manufacturer portfolio.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative 28.0 GHz bandpass filters from the same manufacturer only if they meet identical electrical parameters including 50 Ohm impedance and comparable insertion loss values.
