Overview
The Würth Elektronik 750315745 is a surface-mount common mode choke from the MID-D11 series, utilizing an EE11/6/3 core. It provides an inductance of 140 mH at 10 kHz with a rated current of 90 mA and a typical DC resistance of 39 Ohms. Designed for two-line power filtering, it operates within a temperature range of -40°C to +125°C. The component features a horizontal package with gull-wing terminals, measuring 9.45 mm in height.
Feature Summary
- Dual-line common mode filtering capability for power supply applications
- High inductance value suitable for noise suppression in low-current circuits
- Surface-mount construction with gull-wing leads for automated assembly
Applications
- Power line EMI filtering
- Common mode noise suppression in electronic devices
- Signal integrity protection in low-power circuits
Procurement Notes
Verify the specific datasheet revision when sourcing, as design corrections have been issued for this part number family. Confirm that the required inductance and current ratings align with the 140 mH and 90 mA specifications. Ensure the PCB footprint matches the horizontal gull-wing package dimensions provided in the official mechanical drawings.
Selection Notes
Select this component for applications requiring high common mode impedance at low frequencies. The 90 mA current rating limits its use to low-power signal or auxiliary lines rather than main power rails. Consider the 39 Ohm DC resistance impact on voltage drop if used in series with sensitive loads.
Part Context
This component belongs to the MID-D11 series of PwrChoke components manufactured by Würth Elektronik. These are dual-coil common mode chokes designed for surface-mount technology. The series utilizes EE11/6/3 cores to provide compact filtering solutions for modern electronics requiring efficient noise reduction.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative components based on identical inductance, current rating, and physical footprint requirements.
