Overview
The UU9LFNP-B-B682 is a two-line common mode choke manufactured by Sumida America Components Inc. It features through-hole mounting and is designed for AC line filtering applications. The component exhibits an inductance of 6.8 mH at 1 kHz, with a maximum DC current rating of 250 mA. Its maximum DC resistance is specified as 2.5 Ohms.
Feature Summary
- Provides common mode noise suppression for dual-line circuits
- Utilizes through-hole termination for PCB integration
- Engineered for low-frequency AC line filtering
Applications
- AC power line filtering
- Common mode noise suppression in electronic equipment
- Signal integrity protection in dual-line circuits
Procurement Notes
Verify the exact part number against manufacturer documentation to ensure compatibility with design requirements. Confirm that the through-hole package dimensions and pin configuration match the target PCB layout. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the 250 mA current rating meets the operational demands of the specific circuit application.
Selection Notes
Select this component when designing circuits requiring through-hole common mode chokes for AC lines. Consider the 6.8 mH inductance value for effective low-frequency noise attenuation. Evaluate the 2.5 Ohm DC resistance impact on voltage drop within the power path. Verify that the 250 mA current handling capability aligns with the maximum load current of the system.
Part Context
This component belongs to the UU9LFNP series of common mode chokes from Sumida. The series offers various inductance values and current ratings tailored for different filtering needs. The UU9LFNP-B-B682 specifically targets applications requiring moderate inductance with through-hole construction for robust mechanical attachment.
Replacement Considerations
Direct substitutes may include other Sumida UU9LFNP variants with similar electrical characteristics. Cross-referencing datasheets is essential to confirm matching inductance, current rating, and physical dimensions before substitution.
