Overview
The UU10LFNP-B123 is a through-hole AC common mode choke manufactured by Sumida America Components Inc. It belongs to the UU series and is designed for power line filtering applications. The component features a nominal inductance of 12 mH measured at 1 kHz. It supports a maximum current rating of 340 mA and exhibits a DC resistance of 2.2 Ohms. The device utilizes a two-line configuration suitable for suppressing electromagnetic interference in electronic circuits.
Feature Summary
- Through-hole mounting technology for secure board attachment
- Two-line configuration for differential noise suppression
- AC common mode filtering capability for power lines
Applications
- Power line filtering in electronic equipment
- Electromagnetic interference suppression in AC circuits
- Common mode noise reduction in power supplies
Procurement Notes
Verify the specific package type and pin configuration against the official datasheet before integration. Confirm that the 340 mA current rating meets the operational requirements of the target circuit. Ensure compliance with RoHS standards if required by the end product specifications. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when a through-hole solution is required for AC common mode noise suppression. The 12 mH inductance value is suitable for specific frequency ranges defined by the application design. Consider the 2.2 Ohm DC resistance impact on voltage drop within the power path. Evaluate the physical size constraints associated with through-hole mounting compared to surface mount alternatives.
Part Context
This component is part of the UU series of common mode chokes produced by Sumida. The series includes various inductance values and current ratings tailored for different power line filtering needs. The UU10LFNP-B123 specifically addresses applications requiring through-hole assembly and moderate inductance levels for AC signal integrity.
Replacement Considerations
Consult the official Sumida documentation for verified substitute part numbers within the same series or equivalent performance specifications from other manufacturers.
