Procurement Notes
Verify the specific package type and lead configuration against the official datasheet before procurement. Confirm that the through-hole mounting style aligns with the target PCB design requirements. Ensure the 10A current rating and 170 Ohm impedance specifications meet the circuit's noise suppression needs. Check RoHS compliance status if required by project regulations.
Selection Notes
Select this component when high current handling capacity and effective common mode noise reduction are required. The through-hole format is preferred for applications needing robust mechanical stability and superior heat dissipation. Evaluate the 10A rating against peak load currents to prevent saturation. Consider the 170 Ohm impedance value for the specific frequency range of interference to be suppressed.
