Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure compliance with required impedance and current ratings. Confirm that the selected variant matches the intended application voltage and thermal requirements. Cross-reference the RoHS status and packaging options such as cut tape or reel availability with authorized distributors to align with manufacturing constraints.

Selection Notes

Select this component when space-constrained designs require effective noise filtering without excessive voltage drop. Evaluate the 38 mOhm DC resistance to ensure it meets power loss limitations in the target circuit. Ensure the operating temperature range covers the environmental conditions of the final product assembly.
