Chip Ferrite Bead Procurement Notes

Verify availability status as this component may be discontinued or subject to limited supply constraints. Confirm that the radial leaded package and physical dimensions match the target PCB layout requirements. Ensure the 160 Ohm impedance specification aligns with the intended noise frequency spectrum. Validate that the 7 A current rating exceeds the operational peak currents to prevent saturation or thermal issues during use.

Chip Ferrite Bead Selection Notes

Select this component when a radial ferrite bead with 160 Ohm impedance at 100 MHz is required. Ensure the circuit design accommodates the 7.7 x 2.45 x 9.5 mm footprint. Verify that the operating environment remains within the -25 C to +85 C range. Confirm compatibility with the 10 mOhms maximum DC resistance limit for low-loss signal transmission.
