UU16LFNP-303

Overview

The UU16LFNP-303 is a common mode choke manufactured by Sumida America Components Inc. It features a vertical through-hole mounting style with four PC pins. The component provides a common mode inductance of 30 mH and supports a maximum current rating of 400 mA. Designed for power line filtering, it operates within a standard temperature range suitable for general electronic applications.

Feature Summary

• Vertical through-hole construction with four-pin configuration
• High common mode inductance for effective noise suppression
• Suitable for AC power line filtering applications

Applications

• AC power input filtering
• Common mode noise suppression in power supplies
• EMI reduction in electronic equipment

Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm that the 30 mH inductance and 400 mA current ratings align with the target circuit requirements. Ensure the vertical through-hole package dimensions are compatible with the printed circuit board layout and assembly processes.

Selection Notes

Select this component when high inductance values are required for low-frequency common mode noise attenuation in through-hole designs. Evaluate the physical size constraints to ensure the vertical package fits the enclosure. Compare performance characteristics against surface mount alternatives if space optimization is a priority.

Part Context

This part belongs to the UU16LF series of common mode chokes from Sumida. The series offers various inductance values for different filtering needs. The UU16LFNP-303 specifically targets applications requiring significant common mode impedance at lower frequencies using a robust through-hole form factor.

Replacement Considerations

Check for direct substitutes within the UU16LFNP series with similar inductance and current ratings. Verify pin compatibility and mechanical dimensions before replacing existing components in established designs.
