Overview
The UU9LFBHNP-B902 is a through-hole common mode choke manufactured by Sumida America Components Inc. It features an inductance of 18 mH at 1 kHz and supports a maximum current of 180 mA. The component has a DC resistance (DCR) of 5 Ohms and is designed for two-line applications. This part belongs to the UU9LFBH series and is categorized under common mode chokes within the inductors, chokes, and coils subcategory.
Feature Summary
- Provides common mode noise suppression for two-line circuits
- Designed for through-hole mounting on printed circuit boards
- Constructed as a surface-mount compatible axial leaded component
Applications
- AC power line filtering
- Noise suppression in electronic equipment
- EMI reduction in signal lines
Procurement Notes
Verify the package type carefully, as some sources describe this part as SMD while others specify through-hole. Confirm the exact inductance value and current rating against the official datasheet before integration. Ensure the supplier provides genuine Sumida components with traceable documentation to avoid counterfeit parts.
Selection Notes
Select this component when a 18 mH inductance is required for common mode noise attenuation in low-current applications up to 180 mA. The 5 Ohm DCR should be considered for voltage drop calculations. Verify that the through-hole form factor matches the PCB design requirements compared to similar SMD variants in the same series.
Part Context
This component is part of the UU9LFBH series from Sumida, which includes various common mode chokes with different inductance values and current ratings. The series is designed for general-purpose EMI suppression in consumer electronics and industrial applications requiring reliable noise filtering.
Replacement Considerations
Check for direct substitutes within the UU9LFBH series with matching 18 mH inductance and 180 mA current rating. Verify pin compatibility and physical dimensions if replacing with other manufacturers' through-hole common mode chokes.
