Overview
The Würth Elektronik 742730021 is a radial leaded ferrite bead from the WE-MLS series. It features an impedance of 170 ohms at 100 MHz and supports a DC current rating of 4 A. The component has a resistance of 2000 microhms with a tolerance of ±25%. It is designed for common mode noise suppression in electronic circuits.
Feature Summary
- Radial leaded construction for through-hole mounting
- High current handling capability of 4 A
- Low DC resistance for minimal signal loss
Applications
- Common mode noise suppression
- Power line filtering
- Data line protection
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the radial lead configuration matches the target PCB layout requirements. Ensure compliance with RoHS standards if required by the end product specifications.
Selection Notes
Select this component when high current capacity is required alongside effective high-frequency noise attenuation. The radial package suits applications where space allows for through-hole assembly. Compare impedance characteristics with alternative series to ensure compatibility with the target frequency spectrum.
Part Context
This part belongs to the WE-MLS series, which focuses on high-current ferrite beads. It differs from clamp-on cores by offering a fixed, solderable solution for permanent circuit integration rather than retrofitted cable suppression.
FAQ
