EH28-1.5-02-27M-X

Overview

The EH28-1.5-02-27M-X is a common mode choke manufactured by Schaffner EMC Inc., designed for PCB mounting via through-hole termination. It features a ferrite core and operates within a temperature range of -40°C to +100°C. The component has an inductance of 27 mH with a tolerance of ±15%, a maximum DC current rating of 1.5 A, and a maximum DC resistance of 360 mOhms. Its physical dimensions are 28 mm x 28 mm x 22.9 mm, and it weighs approximately 31 grams.

Feature Summary

• Provides common mode suppression for electromagnetic interference reduction
• Utilizes a ferrite core for effective high-frequency noise attenuation
• Designed for vertical PCB mounting using through-hole technology

Applications

• Power supply input filtering
• Motor drive circuit noise suppression
• Industrial control system EMI mitigation

Procurement Notes

Verify the specific suffix 'X' against the manufacturer's latest datasheet to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact inductance and current ratings required for the target application circuit design.

Selection Notes

Select this component when a 27 mH inductance value is required for common mode noise reduction at currents up to 1.5 A. Consider the 360 mOhms DC resistance for power loss calculations and verify that the 28 mm footprint fits the available PCB space constraints.

Part Context

This part belongs to the EH series of common mode chokes from Schaffner, which are characterized by their robust construction and suitability for industrial environments. The series offers various inductance values tailored for different current requirements and noise suppression needs.

Replacement Considerations

Cross-reference with EH28-1.5-02-20M-X or EH28-1.5-02-36M-X if different inductance values are acceptable. Verify pin compatibility and thermal performance before substituting.
