LF2020BNP-R193

Common Mode Chokes Overview

The LF2020BNP-R193 is a common mode filter choke manufactured by Sumida America Components Inc. It features an inductance of 19 mH measured at a test frequency of 1 kHz. The component supports a current rating of 700 mA and exhibits a maximum DC resistance (DCR) of 900 mOhm. Designed for through-hole mounting, it serves as a two-line common mode coil suitable for noise suppression applications.

Common Mode Chokes Feature Summary

• Provides effective common mode noise filtering for dual-line circuits
• Utilizes through-hole termination for secure PCB integration
• Constructed with shielded magnetic core technology

Common Mode Chokes Applications

• Power supply input filtering
• Data line noise suppression
• EMI reduction in consumer electronics

Common Mode Chokes Procurement Notes

Verify the specific package type and pin configuration against the official datasheet before ordering. Confirm that the 19 mH inductance value meets the circuit requirements. Ensure the 700 mA current rating is sufficient for the intended application load to prevent saturation or overheating during operation.

Common Mode Chokes Selection Notes

Select this component when a high-inductance common mode choke is required for low-current applications. The 900 mOhm DCR offers a balance between impedance and conduction loss. Consider the through-hole form factor if automated surface-mount assembly is not available or if mechanical robustness is prioritized over board space constraints.
