C201371A-102U

Overview

The C201371A-102U is a nanocrystal common mode choke manufactured by ITG Electronics, Inc. It features a through-hole DIP package with four vertical pins. The component provides an inductance of 1 mH at a test frequency of 10 kHz, with a tolerance range of +50% and -30%. It supports a maximum current rating of 2.5 A and exhibits a DC resistance (DCR) of 50 mOhm.

Feature Summary

• Utilizes nanocrystal core material for efficient magnetic performance
• Designed for through-hole mounting via a standard DIP configuration
• Constructed as a two-line common mode choke for differential noise suppression

Applications

• Switch Mode Power Supply (SMPS) input filtering
• EMI suppression in AC/DC converter circuits
• Signal line protection against common mode interference

Procurement Notes

Verify the specific suffix 'U' to confirm compliance with RoHS and Halogen-Free standards as indicated in distributor listings. Ensure the selected variant matches the required 1 mH inductance and 2.5 A current rating for the target circuit design before finalizing orders.

Selection Notes

Select this component when a compact through-hole solution is required for low-frequency common mode noise attenuation. The 50 mOhm DCR minimizes power loss compared to higher resistance alternatives, while the 2.5 A rating suits moderate power applications.

Part Context

This part belongs to the C201371A series of nanocrystal common mode chokes from ITG Electronics. The series offers various inductance values, such as 400 uH and 1.6 mH, sharing similar physical dimensions and mounting styles but differing in electrical characteristics like current handling and impedance.

Replacement Considerations

Direct substitutes within the same series include C201371A-401U (0.4 mH) and C201371A-162U (1.6 mH). Verify that alternative part numbers meet the specific inductance and current requirements of the original design.
