Overview
The Würth Elektronik 744822110 is a common mode power line choke from the WE-CMB series. It features an inductance of 10 mH and a maximum DC current rating of 1 A. The component has a maximum DC resistance (DCR) of 360 mOhms. It operates within a temperature range of -40°C to +125°C. The device utilizes a radial through-hole mounting style with a lead spacing of 7.7 mm.
Feature Summary
- Broadband screening capability achieved through low capacitance winding technique
- Very compact design enabling high current handling in small sizes
- High interference compression for effective noise suppression
Applications
- Power line filtering in electronic equipment
- Common mode noise suppression in AC/DC circuits
- EMI reduction in industrial control systems
Procurement Notes
Verify the specific package type and lead configuration against the official datasheet before integration. Confirm that the 1 A current rating and 360 mOhm DCR meet the circuit requirements. Ensure the operating temperature range of -40°C to +125°C is suitable for the intended environment. Cross-reference the manufacturer part number to avoid counterfeit components.
Selection Notes
Select this component when broadband screening and high interference compression are required for power lines. The low capacitance winding technique makes it suitable for applications sensitive to signal distortion. Consider the compact design if space constraints exist alongside high current demands. Verify compatibility with existing PCB layouts due to the radial through-hole form factor.
Part Context
This component belongs to the WE-CMB series of common mode chokes by Würth Elektronik. These parts are designed for power line applications, offering a balance between size and performance. The series is known for providing high current ratings in compact packages, making them versatile for various industrial and consumer electronics applications requiring EMI suppression.
Replacement Considerations
Check for direct substitutes within the WE-CMB series with similar inductance and current ratings. Verify pinout compatibility for radial through-hole mounting. Ensure replacement parts meet the same temperature and impedance specifications.
