LF2020BNP-R901

Common Mode Chokes Overview

The LF2020BNP-R901 is a two-line common mode choke from Sumida, designed for through-hole mounting. It features an inductance of 900 µH measured at 1 kHz and supports a current rating of 3A. The component has a vertical package with four PC pins. Its direct current resistance (DCR) is specified as 60 mOhm. This filter type is engineered to suppress asymmetric interferences effectively.

Common Mode Chokes Feature Summary

• Compact design delivering high suppression of asymmetric interferences
• Effective performance even at low-frequency ranges
• Two-line configuration for power line filtering

Common Mode Chokes Applications

• Power line noise suppression
• Low-frequency interference filtering
• Asymmetric interference reduction in electronic circuits

Common Mode Chokes Procurement Notes

Verify the specific suffix R901 against official Sumida documentation to confirm the 900 µH inductance and 3A current rating. Ensure the vertical through-hole package matches the PCB layout requirements. Confirm that the 60 mOhm DCR specification aligns with thermal and efficiency constraints. Cross-reference the manufacturer part number to avoid confusion with other variants in the LF2020BNP series.

Common Mode Chokes Selection Notes

Select this component when high suppression of asymmetric noise is required at low frequencies. The 3A current rating suits applications demanding moderate power handling. The vertical through-hole format facilitates manual assembly or specific board orientations. Verify that the 900 µH inductance provides sufficient impedance for the target noise spectrum without causing excessive voltage drop.

Common Mode Chokes Part Context

This component belongs to the LF2020BNP series of common mode chokes manufactured by Sumida America Components Inc. The series includes various inductance values, such as the LF2020BNP-353 and LF2020BNP-622. These components are generally used for EMC filtering in power supply lines. The LF2020BNP-R901 specifically targets applications requiring 900 µH inductance.

Common Mode Chokes Replacement Considerations

Check for exact electrical equivalence if substituting. Other LF2020BNP variants like the LF2020BNP-353 offer different inductance and current ratings. Ensure any replacement maintains the vertical through-hole package and 4-pin configuration. Verify that the substitute component meets the same 3A current and 60 mOhm DCR specifications.
