LF1290NP-471

Common Mode Chokes Overview

The LF1290NP-471 is a vertical through-hole common mode choke manufactured by Sumida America Components Inc. It features two lines with an inductance of 470 µH at 1 kHz and a maximum current rating of 1.1 A. The component utilizes a ferrite core and is designed for power line filtering applications.

Common Mode Chokes Feature Summary

Provides common mode noise suppression for dual-line power circuits
Vertical through-hole mounting configuration for PCB integration

Common Mode Chokes Applications

Power line filtering
EMI suppression in electronic equipment

Common Mode Chokes Procurement Notes

Verify the specific package pin count and lead configuration against the official datasheet to ensure compatibility with the target PCB footprint. Confirm RoHS3 compliance status if required by regulatory standards. Cross-reference the manufacturer part number to distinguish from similar series components.

Common Mode Chokes Selection Notes

Select this component when a dual-line common mode choke with 470 µH inductance is required for power line applications. Ensure the operating current does not exceed the 1.1 A rating. Verify that the vertical through-hole form factor fits the assembly constraints.

Common Mode Chokes Part Context

This component belongs to the LF series of common mode chokes from Sumida. It is distinct from the CDRH and RCH series, which are power inductors. The LF series is specifically engineered for common mode noise reduction rather than energy storage.
