Procurement Notes
Verify the specific part number 744834310 against official Wurth Elektronik documentation to confirm the 10 mH inductance and 3 A current rating. Ensure the horizontal mounting orientation matches the design requirements. Cross-reference technical specifications with authorized distributors to guarantee authenticity and compliance with safety standards such as VDE or RoHS where applicable.
Selection Notes
Select this component when a horizontal form factor is required for through-hole assembly. The 10 mH inductance and 3 A current handling capability suit moderate power applications requiring significant common mode attenuation. Consider the 0.11 Ω DC resistance for efficiency calculations. Verify that the operating temperature range meets the environmental conditions of the target application.
Part Context
This component belongs to the WE-CMBH series from Würth Elektronik, which specializes in common mode chokes utilizing nano-crystal cores.
