750315739

Overview

The Würth Elektronik 750315739 is a dual-coil common mode choke from the MID-D11 series, designed for surface mount technology. It features an unshielded EE11/6/3 core configuration with a nominal inductance of 2.5 mH measured at 10 kHz. The component supports a maximum current rating of 760 mA and exhibits a typical DC resistance of 620 mOhm per coil. This power choke is engineered for efficient electromagnetic interference suppression in compact electronic designs.

Feature Summary

• Dual-coil construction for effective common mode noise attenuation
• Unshielded EE11/6/3 core design optimized for specific footprint constraints
• Surface mount compatibility for automated assembly processes

Applications

• Signal line filtering in data communication interfaces
• Electromagnetic interference suppression in consumer electronics
• Noise reduction in industrial control system signal paths

Procurement Notes

Verify the exact datasheet revision to confirm mechanical dimensions and thermal characteristics before finalizing the design. Ensure that the selected PCB layout accommodates the unshielded form factor to prevent unintended coupling. Cross-reference the manufacturer's official documentation for any updates regarding material composition or environmental compliance standards.

Selection Notes

Select this component when a dual-channel solution is required for differential lines or paired signal traces. The 2.5 mH value provides substantial impedance at lower frequencies compared to standard filter chokes. Consider the 760 mA current limit during peak load analysis to ensure stable operation without saturation. The unshielded nature may influence placement relative to sensitive analog circuits.

Part Context

This part belongs to the MID-D11 product family, which specializes in compact power chokes for space-constrained applications. The series utilizes standardized EE cores to balance performance with manufacturing efficiency. Würth Elektronik integrates these components into broader EMC solutions, offering complementary shielding options for higher isolation requirements.

Replacement Considerations

Direct substitutes include other dual-coil common mode chokes with matching 2.5 mH inductance and similar current ratings. Verify pinout compatibility and physical envelope dimensions to ensure seamless integration into existing footprints without rework.
