EH28-3.0-02-5M0

Overview

The EH28-3.0-02-5M0 is a two-line common mode choke manufactured by Schaffner EMC Inc., designed for power line filtering applications to suppress electromagnetic interference. It features a horizontal through-hole mounting style with four PCB pins and utilizes a ferrite core material. The component provides an inductance of 5 mH at a test frequency of 400 Hz, supporting a maximum DC current of 3 A with a typical DC resistance of 79 mOhms. Its physical dimensions are approximately 28 mm x 28 mm x 23.9 mm, operating within a temperature range of -40°C to +100°C.

Feature Summary

• Provides effective suppression of electromagnetic interference on power lines
• Utilizes a ferrite core for stable inductance performance
• Designed for horizontal through-hole PCB integration

Applications

• Power line filtering in electronic equipment
• Electromagnetic interference suppression circuits
• General-purpose EMI/RFI chokes

Procurement Notes

Verify the manufacturer part number EH28-3.0-02-5M0 against official Schaffner or TE Connectivity documentation to confirm specifications. Ensure compatibility with your PCB layout regarding the four-pin through-hole footprint and horizontal orientation. Cross-reference electrical parameters such as 5 mH inductance and 3 A current rating with your design requirements before procurement.

Selection Notes

Select this component when a 5 mH inductance at 400 Hz is required for two-line power filtering. It is suitable for designs needing a 3 A current rating with low DC resistance. Consider the horizontal through-hole package and specific dimensional constraints of 28 mm x 28 mm x 23.9 mm during mechanical integration.

Part Context

This component belongs to the EH series of common mode chokes from Schaffner EMC Inc., now part of TE Connectivity. The series offers various inductance and current ratings for different power line filtering needs. The EH28-3.0-02-5M0 specifically targets applications requiring moderate inductance and higher current handling capabilities compared to lower-rated variants.

Replacement Considerations

Check for direct substitutes within the EH series, such as EH28-2.0-02-15M-X or EH28-3.0-02-5M0 equivalents from other manufacturers, ensuring identical inductance, current rating, and package dimensions.
