Procurement Notes

Verify the exact impedance value and current rating against the specific application requirements before ordering. Confirm that the 0603 package footprint matches the PCB layout. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check for RoHS compliance documentation if required by regulatory standards.

Selection Notes

Select this component when a 220 Ohm impedance is required at 100 MHz for noise attenuation. The 2.2 A current rating suits moderate power applications. The 0603 size offers a balance between performance and space efficiency. Consider the 50 mOhms DC resistance impact on voltage drop in the circuit path.

Part Context

This part belongs to the WLBD series of ferrite beads from Walsin Technology Corporation. The series includes various impedance values and package sizes, such as the WLBD1608HCU121TL and WLBD1608HCU300TL, which share similar physical dimensions but differ in electrical specifications like impedance and current handling capabilities.

Replacement Considerations

Direct substitutes include other 0603 ferrite beads with 220 Ohms impedance at 100 MHz. Verify compatibility with existing footprints and thermal profiles. Alternative manufacturers may offer similar parts, but electrical parameters must be cross-referenced to ensure equivalent performance in the specific circuit context.
