EH28-4.0-02-2M3

Overview

The EH28-4.0-02-2M3 is a common mode choke manufactured by Schaffner EMC Inc., designed for printed circuit board mounting via through-hole termination. This component features a ferrite core and operates within a temperature range of -25°C to +100°C. It provides an inductance of 2.3 mH with a tolerance of 15%, supporting a maximum DC current of 4 A. The unit has a maximum DC resistance of 60 mOhms and measures 28 mm x 28 mm x 22.9 mm.

Feature Summary

Provides common mode suppression for differential signal lines
Utilizes a ferrite core for effective high-frequency noise attenuation
Designed for reliable through-hole PCB integration

Applications

Differential data line filtering
Power supply input noise suppression
EMI reduction in electronic equipment

Procurement Notes

Verify the manufacturer part number EH28-4.0-02-2M3 against official Schaffner documentation to confirm specifications. Ensure compatibility with required current ratings and thermal operating limits. Check RoHS compliance status as indicated in the datasheet. Confirm package dimensions match the PCB layout constraints before procurement.

Selection Notes

Select this component when a 2.3 mH inductance at 4 A is required for common mode noise reduction. Consider the through-hole mounting style and physical footprint of 28 mm x 28 mm. Evaluate the 60 mOhms DC resistance impact on circuit efficiency. Verify that the operating temperature range meets the application environment requirements.

Part Context

This component belongs to the EH series of common mode chokes from Schaffner EMC Inc. These devices are engineered for EMI suppression in various electronic applications. The series offers multiple inductance values and current ratings to suit different circuit needs while maintaining consistent mounting and performance characteristics.

Replacement Considerations

Cross-reference with other Schaffner EH series parts or equivalent common mode chokes from other manufacturers if availability is limited. Ensure substitute components match the 2.3 mH inductance, 4 A current rating, and through-hole package dimensions.
