Overview
The Würth Elektronik 744841330 is a leaded common mode filter choke from the WE-CMB series, designed for power line applications. It features an inductance of 30 µH at 10 kHz with a maximum DC resistance of 26 mΩ and a current rating of 3 A. The component operates within a temperature range of -40°C to +125°C and has physical dimensions of 15.5 x 7.5 x 17.5 mm.
Feature Summary
- Provides common mode noise suppression for power lines
- Utilizes NiZn core material for effective filtering
- Designed for through-hole PCB mounting
Applications
- Power line EMI filtering
- Common mode noise suppression in electronic equipment
- Power supply input stages
Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with Wurth Elektronik or authorized distributors before procurement. Confirm that the leaded package style matches the target PCB footprint requirements. Ensure the 3 A current rating and 26 mΩ DCR specifications meet the circuit design constraints for the intended application environment.
Selection Notes
Select this component when a through-hole common mode choke with a 30 µH inductance and 3 A current handling capability is required. The low DC resistance of 26 mΩ minimizes power loss in the signal path. Consider the 15.5 x 7.5 x 17.5 mm form factor for spatial constraints on the printed circuit board assembly.
Part Context
This part belongs to the WE-CMB series of NiZn common mode chokes manufactured by Würth Elektronik.
