SN20P-240

Overview

The KEMET SN20P-240 is a through-hole common mode choke belonging to the SN series, designed for AC line filter applications. It features an inductance of 40 µH and supports a DC current (Idc) of 20A with a low DC resistance (Rdc) of 0.010 mΩ. The component utilizes an iron core construction and is RoHS compliant.

Feature Summary

Common mode noise suppression for AC line filtering
High current handling capability up to 20A
Low DC resistance for minimal power loss
Through-hole mounting for robust mechanical stability

Applications

AC line input filtering
EMI suppression in power supplies
Industrial equipment noise reduction

Procurement Notes

Verify the specific package dimensions and lead configuration against your PCB footprint requirements before ordering. Confirm that the 20A current rating aligns with your circuit's maximum operational load. Ensure compatibility with your assembly process for through-hole components. Check for any specific environmental certifications required by your target market regulations.

Selection Notes

Select this component when high current capacity and low impedance are critical for AC line filtering. The 40 µH inductance provides effective common mode noise attenuation. Consider the through-hole form factor if board space allows for larger components requiring higher thermal and mechanical resilience compared to surface mount alternatives.

Part Context

The SN20P-240 is part of KEMET's SN series of common mode chokes. This series is engineered for general-purpose EMI suppression in AC power lines. The use of an iron core allows for high saturation current, making it suitable for applications where significant DC bias currents are present alongside AC line frequencies.
