744242510

Overview

The Würth Elektronik 744242510 is a surface-mount common mode choke from the WE-SLM series. It features an inductance of 51 µH and offers an impedance of 2.5 kOhms at 25 MHz. The component supports a maximum DC current of 400 mA with a maximum DC resistance of 320 mOhms. Rated for 80 V DC, it operates within a temperature range of -40°C to +125°C. Dimensions are 6.00 mm length, 3.30 mm width, and 3.50 mm height.

Feature Summary

Provides effective suppression of common mode noise on signal lines
Designed for compact surface-mount PCB integration
Capable of handling high current loads relative to its small form factor

Applications

Signal line filtering in electronic circuits
Noise suppression in data transmission interfaces
EMI mitigation in consumer electronics

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as cut tape or reel quantities. Confirm that the voltage rating and current specifications align with the target circuit requirements. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range meets the environmental conditions of the intended application.

Selection Notes

Select this component when space constraints require a low-profile SMD filter with moderate current handling capabilities. The 51 µH inductance value is suitable for filtering specific frequency bands where 2.5 kOhm impedance provides adequate attenuation. Consider the 320 mOhms DCR impact on power loss and thermal management within the design.

Part Context

This part belongs to the WE-SLM series of common mode chokes manufactured by Würth Elektronik. The series is characterized by small physical dimensions and high current capability, making it suitable for modern dense PCB layouts. It serves as a passive component for electromagnetic interference reduction in various electronic systems.
