LF2420NP-203

Common Mode Chokes Overview

The LF2420NP-203 is a through-hole common mode choke manufactured by Sumida America Components Inc. It features an inductance of 20 mH at 1 kHz and supports a current rating of 700 mA. The component has a DC resistance (DCR) of 870 mOhm. It utilizes a wirewound construction and is available in a 4-pin package designed for vertical PCB mounting.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for two-line circuits
• Utilizes wirewound technology for stable inductance performance
• Designed for through-hole vertical mounting on printed circuit boards

Common Mode Chokes Applications

• AC power line filtering
• Noise suppression in electronic equipment input stages
• EMI reduction in consumer electronics

Common Mode Chokes Procurement Notes

Verify the specific suffix and pin configuration against the official Sumida datasheet to ensure compatibility with your PCB footprint. Confirm that the 700 mA current rating meets your application's peak load requirements. Check for RoHS compliance status as indicated in the manufacturer documentation before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a 20 mH inductance value is required for common mode noise attenuation in low-current applications. Ensure the 870 mOhm DCR aligns with your power loss constraints. Verify that the through-hole form factor fits your assembly process and board design constraints compared to surface mount alternatives.

Common Mode Chokes Part Context

This part belongs to the LF series of common mode chokes from Sumida. It is distinct from the UU16LFNP-203, which is a surface mount device, and the CEI122NP-3R0MC-H, which is a power inductor. The LF2420NP-203 is specifically engineered for through-hole applications requiring higher inductance values than typical SMD solutions.

Common Mode Chokes Replacement Considerations

The LF2420NP-B-153 is a related variant within the same family but offers different electrical specifications. Verify inductance and current ratings carefully when substituting. No other direct cross-model replacements are confirmed in public documentation.
