750341780

Overview

The Würth Elektronik part number 750341780 is a through-hole common mode choke belonging to the WE-CMC series. It features dual lines with an inductance of 42 mH and a maximum DC current rating of 500 mA. The component exhibits a maximum DC resistance of 1.94 Ohms. It is designed for operation within a temperature range of -40°C to +125°C.

Feature Summary

• Provides common mode noise suppression via dual-line configuration
• Supports high-temperature environments up to 125°C
• Utilizes through-hole mounting technology for PCB integration

Applications

• Signal line filtering in electronic circuits
• Noise suppression in data transmission interfaces
• EMI reduction in power supply input stages

Procurement Notes

Verify the manufacturer datasheet to confirm electrical parameters such as inductance and current ratings match system requirements. Ensure the through-hole package dimensions align with the printed circuit board layout. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when dual-line common mode filtering is required for signals carrying up to 500 mA. The 42 mH inductance value determines the attenuation characteristics at specific frequencies. Verify that the 1.94 Ohm DC resistance does not cause excessive voltage drop in the application circuit.

Part Context

This component is part of the WE-CMC series from Würth Elektronik, which specializes in magnetic components for electromagnetic interference suppression. The series offers various inductance values and current ratings to suit different signal integrity needs in industrial and consumer electronics.

Replacement Considerations

Consult official Wurth Elektronik documentation for verified substitute part numbers within the WE-CMC family. Ensure any replacement maintains equivalent inductance, current handling, and physical footprint specifications.
