UU9LFNP-B-B103

Overview

The UU9LFNP-B-B103 is a through-hole common mode choke manufactured by Sumida America Components Inc. It features an inductance of 10 mH at 1 kHz and supports a maximum DC current of 200 mA. The component has a DC resistance of 4 Ohms and utilizes a vertical, 4-pin package configuration. Designed for power line applications, it operates within a temperature range suitable for standard industrial environments.

Feature Summary

• Provides effective common mode noise suppression for AC power lines
• Utilizes a robust through-hole mounting style for secure PCB attachment
• Engineered with low DC resistance to minimize power loss

Applications

• AC power line filtering
• Noise suppression in electronic equipment
• EMI reduction in power supply circuits

Procurement Notes

Verify the specific suffix B-B103 against official Sumida documentation to confirm pinout and electrical ratings. Ensure compatibility with existing PCB footprints before ordering. Confirm RoHS compliance status via the manufacturer's datasheet. Check lead times as they may vary based on production schedules.

Selection Notes

Select this component when high inductance is required for low-frequency noise attenuation. The 200 mA current rating suits low-power AC applications. Verify that the 4-pin through-hole package fits the assembly constraints. Compare DCR specifications against thermal management requirements.

Part Context

This part belongs to Sumida's UU9LFNP series of common mode chokes. The series offers various inductance values tailored for different filtering needs. The UU9LFNP-B-B103 specifically targets applications requiring higher inductance compared to lower-value variants in the same family.

Replacement Considerations

Check Sumida's official substitution guide for equivalent parts. Verify that any alternative maintains the 10 mH inductance and 200 mA current rating. Ensure physical dimensions and pin configurations match to avoid PCB redesign.
