ECMT1V2429S-300-R

Common Mode Chokes Overview

The Eaton ECMT1V2429S-300-R is a single-channel common mode choke designed for through-hole PCB mounting. It features an inductance of 30 mH and supports a maximum DC current of 600 mA. The component has a maximum DC resistance of 1.6 Ohms and an open-circuit inductance of 1500 µH. Its self-resonant frequency is 276 kHz, with a minimum operating temperature of -40°C and a maximum of +125°C. The unshielded unit measures 29 mm in length, 20 mm in width, and 24 mm in height.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression via dual-line filtering architecture
• Utilizes vertical through-hole termination for standard PCB integration
• Operates reliably across a wide industrial temperature range

Common Mode Chokes Applications

• Power supply input filtering
• Data line noise suppression
• EMI reduction in electronic circuits

Common Mode Chokes Procurement Notes

Verify the specific suffix '300' to confirm the 30 mH inductance rating, as the ECMT1V2429S series includes variants with different values such as 100 or 5R0. Ensure the through-hole package dimensions align with the target PCB footprint. Confirm RoHS compliance status directly from the manufacturer's documentation prior to final procurement decisions.

Common Mode Chokes Selection Notes

Select this component when a 30 mH common mode choke is required for applications handling up to 600 mA DC current. The unshielded design suits environments where magnetic interference with adjacent components is not a primary constraint. Verify that the 1.6 Ohm DC resistance meets the voltage drop requirements of the circuit design.

Common Mode Chokes Part Context

This part belongs to the Eaton ECMT-R series of common mode chokes. These components are engineered for general-purpose EMI suppression in electronic assemblies. The series offers various inductance options within a standardized through-hole form factor, allowing designers to select appropriate filtering characteristics while maintaining consistent mechanical integration across different product lines.

Common Mode Chokes Replacement Considerations

Direct substitutes include other Eaton ECMT1V2429S variants with identical physical dimensions but different inductance values, such as ECMT1V2429S-100-R or ECMT1V2429S-5R0-R, provided the electrical specifications match the circuit requirements.
