Procurement Notes

Verify the specific ordering suffix and packaging configuration, as availability may vary between cut tape and reel formats. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory classifications can differ based on production batches and regional requirements. Ensure the nonstandard lead configuration matches the target PCB footprint design constraints.

Selection Notes

Select this component when precise inductance control is critical for high-frequency performance. The low DC resistance helps minimize power loss in sensitive RF paths. Consider the physical dimensions carefully due to the unique lead arrangement. Evaluate the Q factor requirements against the operating frequency to ensure adequate circuit efficiency and signal integrity.
