LF2020BNP-R823

Common Mode Chokes Overview

The LF2020BNP-R823 is a two-line common mode choke manufactured by Sumida America Components Inc. It features through-hole mounting with vertical, four-pin configuration. The component provides an inductance of 82 mH measured at 1 kHz and supports a current rating of 300 mA. Its direct current resistance (DCR) is specified as 4.1 Ohms. Designed for power line filtering applications, it complies with RoHS standards and is lead-free.

Common Mode Chokes Feature Summary

• Provides effective noise suppression for two-line power circuits
• Utilizes vertical through-hole pin configuration for PCB integration
• Constructed with lead-free materials compliant with environmental regulations

Common Mode Chokes Applications

• Power line filtering
• AC common mode coil applications

Common Mode Chokes Procurement Notes

Verify the specific manufacturer designation, as sources list both Sumida Corporation and Sumida America Components Inc. Confirm the package style matches the vertical, four-pin requirement. Ensure the 82 mH inductance value aligns with circuit design needs. Check RoHS compliance status if required by project specifications. Validate the 300 mA current rating against operational loads.

Common Mode Chokes Selection Notes

Select this component when a high-inductance common mode choke is required for low-current AC power lines. The 82 mH value offers significant impedance to common mode noise. The through-hole format suits designs requiring robust mechanical anchoring. Verify that the 4.1 Ohm DCR does not introduce excessive voltage drop in the target application.

Common Mode Chokes Part Context

This part belongs to the category of passive components, specifically common mode chokes or filters. Sumida Corporation manufactures these inductive components globally. The LF2020BNP series represents their offering in this segment, designed for electromagnetic interference suppression in electronic systems.

Common Mode Chokes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 82 mH inductance, 300 mA current rating, and vertical through-hole package dimensions.
