Overview
The UU9LFNP-B222 is a common mode choke manufactured by Sumida America Components Inc. It features an inductance of 2.2 mH at 1 kHz and supports a maximum DC current of 500 mA. The component has a maximum DC resistance (DCR) of 700 mOhms. It is designed for surface mount technology (SMD) applications, specifically as an AC common mode choke.
Feature Summary
- Provides common mode noise filtering for AC power lines
- Designed for surface mount PCB integration
- Constructed as a dual-line choke for differential signal suppression
Applications
- AC power line filtering
- Common mode noise suppression in electronic circuits
Procurement Notes
Verify the specific package type and termination style against the official datasheet, as naming conventions may vary between through-hole and surface mount variants within the same series. Confirm the exact inductance tolerance and current ratings required for your design before ordering. Ensure compatibility with your assembly process regarding soldering temperatures and reflow profiles specified by the manufacturer.
Selection Notes
Select this component when a 2.2 mH inductance value is required for common mode noise reduction in AC applications. Consider the 500 mA current rating to ensure it meets the operational load without saturation. Evaluate the physical footprint constraints on the PCB to ensure the SMD package fits the designated area. Compare DCR specifications against efficiency requirements for the target circuit.
Part Context
This part belongs to the UU9LFB series of common mode chokes from Sumida. The series typically includes various inductance values and current ratings tailored for different power line filtering needs. The UU9LFNP-B222 specifically addresses applications requiring moderate inductance with low current handling capabilities in a compact form factor.
Replacement Considerations
Check for direct substitutes such as UU9LFNP-B-B222 if pinout or mounting differences exist. Verify equivalent electrical parameters including inductance, DCR, and current rating before substituting. Ensure the replacement part matches the required package type and thermal characteristics.
