Procurement Notes

Verify the specific datasheet version and electrical parameter tolerances against the manufacturer's official documentation before integration. Confirm that the 17-SMD footprint matches the target PCB layout. Ensure compliance with RoHS3 and REACH regulations as stated in the product specifications. Check for any required evaluation boards or specific mounting considerations detailed in the official mechanical drawings.

Selection Notes

Select this component when a shielded, surface-mount bandpass filter with a 1.28GHz center frequency is required. The 240MHz bandwidth and 2dB insertion loss define its spectral performance. Consider the 17-SMD module size for space-constrained designs. Verify impedance matching at 50 Ohms for the intended circuit environment.
