Procurement Notes

Verify the specific datasheet version for the B111NC4S-T to confirm exact electrical tolerances and mechanical dimensions prior to integration. Ensure compatibility with the target PCB layout regarding the surface-mount footprint. Confirm that the operating environment remains within the specified -55°C to +125°C thermal limits to maintain performance integrity.

Selection Notes

Select this component when a fixed center frequency of 11.40 GHz is required for signal processing. The 2.55 GHz bandwidth defines the passband characteristics suitable for specific channel allocations. Consider the 2.25 dB insertion loss impact on system gain budgets during circuit design. The surface-mount package facilitates automated assembly processes for high-volume manufacturing.

Part Context

This part belongs to the Knowles Dielectric Labs Surface-Mount Bandpass Filter series, which provides high-performance 50-ohm solutions for microwave applications.
