Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm terminal type and packaging configuration. Ensure that the selected variant matches the required impedance tolerance and current rating for the target application circuit. Cross-reference the RoHS compliance status and lead-free certification requirements with project specifications before finalizing procurement orders.

Selection Notes

Select this component based on the required impedance value at the specific operating frequency and the available board space constraints. Evaluate the maximum DC current rating to ensure it exceeds the peak current demands of the circuit without causing excessive self-heating. Consider the thermal performance and physical dimensions relative to adjacent components to prevent mechanical interference or thermal issues.
