UU10LFNP-B333

Overview

The UU10LFNP-B333 is a through-hole AC common mode choke manufactured by Sumida America Components Inc. It features a vertical package with four pins and is designed for power line filtering applications. The component provides an inductance of 33 mH at 1 kHz, with a maximum DC resistance of 5.74 Ohms and a current rating of 200 mA. It belongs to the UU series and serves as a filter type for two-line configurations.

Feature Summary

• Provides electromagnetic interference suppression for power lines
• Designed for through-hole mounting on printed circuit boards
• Constructed with a vertical pin configuration for space-efficient installation

Applications

• Power line filtering in electronic equipment
• Common mode noise suppression in two-line circuits
• Electromagnetic compatibility enhancement in consumer electronics

Procurement Notes

Verify the specific suffix B333 against official Sumida documentation to confirm the exact inductance value and tolerance. Ensure the through-hole vertical package matches the target PCB layout requirements. Confirm RoHS compliance status directly from the manufacturer's datasheet before integration into regulated products.

Selection Notes

Select this component when a high-inductance common mode choke is required for low-current power line applications. The 200 mA rating limits suitability to low-power circuits. Consider the 5.74 Ohm DC resistance impact on voltage drop within the design constraints. Verify thermal performance under continuous operating conditions.
