Procurement Notes

Verify the specific impedance tolerance and current rating against the official datasheet before procurement, as values may vary by revision. Confirm the package dimensions match the PCB footprint requirements. Ensure the supplier provides original manufacturer documentation to validate authenticity and technical specifications.

Selection Notes

Select this component when space constraints require an 0805 footprint for high-frequency noise attenuation. Consider the 200 mA current rating to ensure adequate headroom for the target circuit's DC load. Evaluate the 300 ohm impedance at 100 MHz to confirm compatibility with the specific frequency spectrum of the interference being suppressed.
