LF2020BNP-353

Common Mode Chokes Overview

The LF2020BNP-353 is a common mode choke manufactured by Sumida America Components Inc. It features an inductance of 35 mH at a test frequency of 1 kHz and supports a rated current of 400 mA. The component has a maximum DC resistance (DCR) of 2.6 Ohms. Designed for through-hole mounting, it serves as a two-line filter to suppress electromagnetic interference.

Common Mode Chokes Feature Summary

• Provides effective suppression of common mode noise in electronic circuits
• Utilizes a robust through-hole construction for secure board attachment
• Engineered for reliable performance in single-phase filtering applications

Common Mode Chokes Applications

• Single-phase EMI filtering
• Power supply input stages
• Signal line noise suppression

Common Mode Chokes Procurement Notes

Verify the specific package type and lead configuration against the official datasheet before integration. Confirm that the 400 mA current rating meets the operational requirements of the target circuit. Ensure the 35 mH inductance value aligns with the necessary filtering specifications for the application environment.

Common Mode Chokes Selection Notes

Select this component when a high inductance value is required for low-frequency noise attenuation. The through-hole format is suitable for applications requiring mechanical stability. Evaluate the 2.6 Ohm DCR to ensure voltage drop and power loss remain within acceptable limits for the system design.

Common Mode Chokes Part Context

This part belongs to the Sumida family of common mode chokes designed for electromagnetic compatibility. It addresses noise issues in sensitive electronics by attenuating unwanted signals. The component is distinct from differential mode inductors due to its dual-line filtering capability.
