Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Knowles Dielectric Labs or authorized distributors before procurement. Confirm that the 12-SMD package dimensions align with your PCB footprint requirements. Ensure that the operating temperature range meets your environmental specifications. Cross-reference the part number to distinguish between reel and bulk packaging options if applicable.

Selection Notes

Select this component when a fixed center frequency of 42.4 GHz is required for bandpass filtering. Consider the 3.25 dB insertion loss impact on system gain budget. Evaluate the physical size constraints due to the 12-SMD package. Verify compatibility with standard SMT assembly processes for no-lead components. Assess thermal management needs given the wide operating temperature range.
