Overview
The UU9LFNP-B-B222 is a common mode choke from the Sumida UU series, designed for AC line filtering applications. It features a vertical through-hole mounting style with four pins and measures 16.5 mm in length, 11 mm in width, and 16.5 mm in height. The component provides an inductance of 2.2 mH at 1 kHz and supports a maximum DC current of 500 mA. Its maximum DC resistance is specified at 700 mOhms, ensuring efficient power transmission while suppressing electromagnetic interference.
Feature Summary
- Vertical through-hole construction for secure PCB integration
- Dual-line configuration for effective AC noise suppression
- Compact physical dimensions suitable for space-constrained designs
Applications
- AC power line filtering in consumer electronics
- Electromagnetic interference suppression in industrial equipment
- Common mode noise reduction in power supply inputs
Procurement Notes
Verify the specific package type and pin configuration against the official datasheet before procurement. Confirm that the 500 mA current rating meets the application requirements. Ensure compatibility with the intended PCB footprint and mounting orientation. Check for any RoHS compliance documentation if required by regional regulations.
Selection Notes
Select this component when a through-hole solution is preferred over surface mount alternatives. The 2.2 mH inductance value is suitable for low-frequency noise attenuation. Consider the 700 mOhm DCR impact on voltage drop in high-current scenarios. Evaluate the physical size constraints to ensure the 16.5 mm height fits within the enclosure limits.
Part Context
This part belongs to the Sumida UU series of common mode chokes, which are engineered for general-purpose EMI suppression. The series offers various inductance values and current ratings to accommodate different power line requirements. The UU9LFNP variant specifically denotes the through-hole packaging option within this product family.
Replacement Considerations
Direct substitutes may include other Sumida UU series parts with similar inductance and current ratings. Verify pin compatibility and physical dimensions before substitution. Alternative manufacturers may offer comparable components, but electrical characteristics must be matched precisely.
