Common Mode Chokes Procurement Notes

Verify the specific ordering suffix and packaging format required for production integration. Confirm that the vertical pin configuration matches the target board layout. Ensure the 600 mA current rating and 1.3 Ohm DCR specifications align with the circuit design requirements before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when a high-inductance common mode choke is required for low-current power lines. The vertical through-hole design offers mechanical stability compared to surface mount alternatives. Evaluate the 18 mH value against the target frequency range to ensure effective attenuation of unwanted common mode signals without impacting desired differential signals.

Common Mode Chokes Part Context

This component belongs to the LF series of common mode chokes from Sumida America Components Inc. These components are specialized for filtering electromagnetic interference in power supply inputs. The LF2020BNP-183 specifically addresses scenarios requiring robust noise reduction in compact vertical form factors for dual-line protection.

Common Mode Chokes Replacement Considerations

Consult official Sumida documentation for verified substitute part numbers within the LF series or compatible families. Ensure any replacement maintains the 18 mH inductance, 600 mA rating, and vertical four-pin through-hole footprint to guarantee mechanical and electrical compatibility.
