EH28-4.0-02-3M5-X

Overview

The EH28-4.0-02-3M5-X is a two-line common mode choke manufactured by Schaffner EMC Inc., designed for through-hole mounting. It features an inductance of 3.5 mH at 400 Hz and supports a maximum current rating of 4 A. The component exhibits a maximum DC resistance of 52 mOhms, ensuring low insertion loss in power line applications. Its vertical construction facilitates efficient PCB layout integration.

Feature Summary

Provides effective suppression of common mode electromagnetic interference on dual-line circuits
Utilizes a robust vertical through-hole package for secure mechanical attachment
Engineered for high-current handling capabilities up to 4 amperes

Applications

Power supply input filtering
Industrial equipment EMI suppression
Consumer electronics noise reduction

Procurement Notes

Verify the manufacturer designation as Schaffner EMC Inc. or TE Connectivity Schaffner during sourcing. Confirm the specific part number suffix matches the required 3.5 mH inductance and 4 A current rating. Ensure the through-hole termination style aligns with the target printed circuit board design specifications before finalizing procurement orders.

Selection Notes

Select this component when dual-line common mode noise attenuation is required in space-constrained vertical layouts. The 52 mOhm DC resistance offers a balance between filtering performance and power efficiency. Consider the 4 A current capacity against peak load requirements to prevent saturation and ensure reliable long-term operation under thermal stress conditions.

Part Context

This component belongs to the EH28 series of common mode chokes from Schaffner, which are widely utilized in electromagnetic compatibility solutions. The series typically includes various inductance values and current ratings to suit different power line filtering needs across industrial and commercial electronic systems.

Replacement Considerations

Cross-reference with other Schaffner EH28 variants such as EH28-3.0-02-9M0-X or EH28-2.0-02-15M-X if different inductance or current characteristics are needed. Verify pinout compatibility and physical dimensions before substituting with components from other manufacturers.
