Product Description
Wurth Elektronik 744834433 surface mount common mode choke from the WE-CMBH series features a ferrite core and a moulded construction delivering 3.3 mH inductance with a tolerance of ±30% and supports a maximum DC current of 5 A. Designed for power line filtering and radio interference suppression, this component is ideal for industrial, automotive, and power electronic applications requiring noise attenuation and signal integrity.
The WE-CMBH series incorporates a horizontal design with low capacitance winding style that provides broadband screening and low frequency noise suppression. It operates reliably in harsh environments within a broad temperature range of -40°C to 125°C.
This common mode choke has a package size of 32.5 mm in length, 28 mm in depth, and 22 mm in height, with a 4-pin surface mount termination style enabling easy installation on PCBs. Its maximum DC resistance is 37 mΩ, ensuring minimal power loss during operation.
The product complies with RoHS and REACH regulations and meets IEC 61249-2-21 standards, assuring environmental and quality standards are upheld. This choke is designed to suppress common mode noise effectively in power electronics circuits and motor radio interference suppression.
Its horizontal, moulded design enhances durability and performance stability under operational stress. Non-shielded construction allows for broadband suppression while maintaining small package size. It is suitable for use in industrial machinery, automotive electronics, power supplies, and general EMI filter applications.
The ferrite core material supports high-frequency performance and thermal endurance.
EnvMart offers this Wurth Elektronik WE-CMBH Series Common Mode Choke for OEMs, electronic component manufacturers, and design engineers seeking reliable Surface Mount Inductors with proven noise suppression characteristics.
