UU9LFHNP-HB392

Overview

The UU9LFHNP-HB392 is a through-hole AC common mode choke from the Sumida UU9LFHNP series. It features an inductance of 3.9 mH measured at 1 kHz and supports two lines. The component has a maximum DC current rating of 380 mA and a DC resistance (DCR) of 1.2 Ohms. It utilizes a vertical package with four PC pins for PCB mounting.

Feature Summary

• Provides common mode noise suppression for AC circuits
• Designed for surface or board mounting via through-hole technology
• Constructed for stable performance in power line filtering applications

Applications

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

Procurement Notes

Verify the specific suffix HB392 to confirm the 3.9 mH inductance value and 380 mA current rating. Ensure the through-hole vertical package with four pins matches the target PCB footprint. Confirm RoHS compliance status if required by project specifications before finalizing procurement.

Selection Notes

Select this component when a through-hole solution is required for AC common mode noise suppression. The 3.9 mH inductance and 380 mA current handling capability suit low-power AC applications. Verify that the 1.2 Ohm DCR meets the voltage drop requirements of the circuit design.

Part Context

This part belongs to the UU9LFHNP series of common mode chokes manufactured by Sumida America Components Inc. The series offers various inductance values and current ratings. The UU9LFHNP-HB392 specifically targets applications requiring through-hole mounting for robust mechanical connection.

Replacement Considerations

Check for other UU9LFHNP variants with similar inductance and current ratings. Verify pin compatibility and physical dimensions before substituting.
