Overview
The UU16LFNP-203 is a through-hole common mode choke manufactured by Sumida America Components Inc. It belongs to the UU16LF series and is designed for AC line filtering applications. The component features an inductance of 20 mH measured at 1 kHz and supports a maximum current rating of 500 mA. Its direct current resistance (DCR) is specified as 1.6 Ohms. This two-line filter is constructed for surface or panel mounting via through-hole technology, providing electromagnetic interference suppression for power lines.
Feature Summary
- Provides common mode noise attenuation for dual-line AC power circuits
- Utilizes through-hole termination for secure mechanical mounting
- Engineered for high-inductance performance in compact form factors
Applications
- AC power input filtering for consumer electronics
- Electromagnetic interference suppression in medical equipment power supplies
- Noise reduction in industrial control system power lines
Procurement Notes
Verify the specific package dimensions and pin configuration against the official Sumida datasheet before integration. Confirm that the 500 mA current rating and 1.6 Ohm DCR meet the thermal and voltage drop requirements of the target circuit design. Ensure compliance with RoHS directives if required by the end product specifications.
Selection Notes
Select this component when a 20 mH inductance value is required for low-frequency common mode noise suppression. The through-hole construction is suitable for applications requiring robust mechanical stability. Consider the 500 mA current limit to ensure adequate headroom for peak load conditions without saturation.
Part Context
This part is part of the UU16LF series of common mode chokes from Sumida. The series offers various inductance values tailored for different power line filtering needs. The UU16LFNP-203 specifically targets applications requiring moderate inductance with through-hole compatibility, distinguishing it from surface-mount alternatives in the same family.
Replacement Considerations
Consult Sumida's official cross-reference documentation for verified substitutes. Ensure any replacement maintains the 20 mH inductance, 500 mA current rating, and through-hole footprint to guarantee electrical and mechanical compatibility.
