Overview
The AUU98-4445 is a common mode choke manufactured by Allied Components International. It features a 1.8 mH inductance and supports a minimum current rating of 340 mA. The component is designed for through-hole mounting and includes two lines. It functions as a line filter to suppress electromagnetic interference.
Feature Summary
- Provides common mode noise suppression via dual-line filtering
- Designed for through-hole board mounting applications
Applications
- Electromagnetic interference suppression in electronic circuits
- Line filtering for signal integrity maintenance
- Power supply input/output noise reduction
Procurement Notes
Verify the specific datasheet version from Allied Components International or authorized distributors to confirm RoHS3 compliance status and exact mechanical dimensions. Ensure the through-hole footprint matches the target PCB layout before procurement. Cross-reference the 1.8 mH inductance and 340 mA current rating with system requirements to validate performance suitability.
Selection Notes
Select this component when a through-hole common mode choke with 1.8 mH inductance is required for low-current applications up to 340 mA. Consider the physical size constraints associated with horizontal or vertical mount variants if space is limited. Verify that the dual-line configuration aligns with the circuit topology requiring common mode noise rejection.
Part Context
Allied Components International specializes in custom and standard magnetic components, including transformers and inductors. The AUU98-4445 belongs to their range of industry-standard magnetic modules used in commercial and industrial markets. The company has been manufacturing these components since 1992, focusing on networking and telecommunications applications.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Users must verify compatibility with alternative common mode chokes based on inductance, current rating, and mounting type specifications.
