C20530A-452

Overview

The C20530A-452 is a two-line common mode choke manufactured by ITG Electronics, Inc. It features an inductance of 4.5 mH measured at 10 kHz and supports a maximum current rating of 17 A. The component utilizes a through-hole mounting style with a DC resistance (DCR) of 5.6 mOhm. It is rated for an AC voltage of 250 V and belongs to the C20530A series of DIP common mode chokes.

Feature Summary

• Provides common mode noise suppression for two-line circuits
• Designed for through-hole PCB mounting applications
• Constructed as a high-current magnetic component

Applications

• Power supply input filtering
• EMI suppression in AC line circuits
• Industrial equipment power stages

Procurement Notes

Verify the specific part number C20530A-452 against official ITG Electronics documentation to confirm the 4.5 mH inductance and 17 A current ratings. Ensure the through-hole package dimensions match the target PCB layout. Confirm that the 5.6 mOhm DCR specification meets the thermal requirements of the application design.

Selection Notes

Select this component when a high-current common mode choke is required for two-line filtering. The 17 A rating distinguishes it from lower-current variants within the same series. Verify that the 4.5 mH inductance value provides sufficient attenuation for the specific noise frequencies encountered in the target circuit environment.

Part Context

This component belongs to the C20530A series of DIP common mode chokes produced by ITG Electronics, Inc. The series includes various inductance values tailored for different current and filtering requirements. The C20530A-452 specifically addresses high-current applications requiring robust EMI suppression capabilities.

Replacement Considerations

Consult ITG Electronics datasheets for direct substitutes within the C20530A series. Verify equivalent inductance, current rating, and physical footprint before substituting with components from other manufacturers.
