Procurement Notes

Verify the specific ordering suffix and package variant against official Panasonic documentation before procurement, as designations may vary. Confirm the lifecycle status, which is listed as obsolete in some distributor records, to ensure long-term supply availability or identify suitable alternative components for new designs.

Selection Notes

Select this component when shielding data lines from noise in the 450-550 MHz band is required. Ensure the application voltage does not exceed 50V and the peak current remains within the 2A limit. Verify that the 1807 footprint aligns with the PCB layout constraints and thermal requirements of the target device.
