LF2823NP-393

Common Mode Chokes Overview

The LF2823NP-393 is a two-line common mode choke manufactured by Sumida America Components Inc. It features a vertical through-hole package with four pins and is designed for AC common mode applications. The component provides an inductance of 39 mH at a test frequency of 1 kHz. It supports a maximum current rating of 700 mA and has a DC resistance of 1.43 Ohms. The device complies with ROHS3 standards.

Common Mode Chokes Feature Summary

• Provides effective common mode noise suppression for two-line circuits
• Utilizes a vertical through-hole mounting style for secure PCB integration
• Constructed as an AC common mode coil for signal integrity

Common Mode Chokes Applications

• AC power line filtering
• Common mode noise suppression in electronic circuits
• Signal integrity protection in two-line interfaces

Common Mode Chokes Procurement Notes

Verify the specific suffix NP-393 to confirm the 39 mH inductance value, as variations exist within the LF2823 series. Ensure the vertical through-hole pin configuration matches the target PCB footprint. Confirm ROHS3 compliance requirements against project specifications before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a high inductance value of 39 mH is required for low-frequency common mode noise attenuation. The 700 mA current rating suits applications with moderate line currents. The through-hole format is appropriate for designs prioritizing mechanical stability over compact surface-mount density.

Common Mode Chokes Part Context

This part belongs to the LF2823 series of common mode chokes from Sumida. The series offers various inductance options, such as 22 mH variants, while maintaining consistent physical dimensions and mounting styles. It serves as a specialized passive component for electromagnetic interference mitigation in AC environments.

Common Mode Chokes Replacement Considerations

The LF2823NP-223 is a related variant within the same series but differs significantly in inductance (22 mH) and current rating (1 A). Substitution requires careful evaluation of the circuit's noise spectrum and current handling capabilities to ensure adequate performance.
