Procurement Notes
Verify the exact datasheet version from Premier Magnetics before procurement. Confirm that the 180mA current rating and 47mH inductance meet specific circuit requirements. Ensure through-hole footprint compatibility with the target PCB design. Check RoHS compliance status if required by project specifications.
Selection Notes
Select this component when low inductance values are sufficient for high-frequency noise attenuation. The 180mA rating suits low-power applications. Consider the through-hole package for mechanical stability. Evaluate thermal performance within the specified -40°C to 80°C range for environmental suitability.
