Procurement Notes

Verify component authenticity through authorized channels due to potential supply chain variations. Confirm RoHS status as documentation indicates non-compliance. Validate lot traceability against specific project requirements. Ensure storage conditions maintain integrity prior to assembly. Cross-reference datasheet revisions for any parameter updates before final design approval.

Selection Notes

Select this component for applications requiring precise low-inductance values with minimal tolerance deviation. Consider the 278 mOhm DCR limit for power loss calculations. Evaluate the 195 MHz self-resonant frequency to ensure operation remains below the resonance point. Assess thermal management capabilities given the 125°C maximum operating temperature rating.
