Common Mode Chokes are electrical components used to filter out common mode signals from DC power applications and other systems. The UU16LFNP-303 is a common mode choke made by Sola/Hevi-Duty that is designed to reduce electromagnetic interference (EMI) and common mode noise in various industrial applications. It is composed of a ferrite core, a coil, and a shield to protect against shocks and vibrations.

The UU16LFNP-303 operates by allowing only differential mode signals through the choke. Common mode signals, which have equal magnitudes in opposite directions, generate magnetic fields that interfere with the system. The UU16LFNP-303 filters out these signals, reducing EMI. The coil and ferrite core work together to create a magnetic field around the core. This field is stronger than the common mode signals, so they are unable to pass through. The sharper curves of the suffocation area, however, allow differential mode signals to pass through.

The UU16LFNP-303 is principally used in power applications to reduce conducted and radiated emissions, including alternating current (AC) and direct current (DC). Other applications include telecommunications, medical imaging, data communications, and military/defense systems. The UU16LFNP-303 is a shielded version, meaning it includes an added shield for extra protection against high frequency signals and further elimination of EMI. It is suitable for both indoor and outdoor applications, as it is designed for harsh industrial environments.

The operating temperature of the UU16LFNP-303 is -40°C to +125°C, with a maximum current of 7A, linear DC current up to 6A, and peak AC current of 16A. It also features a minimum air gap of 0.05” and a minimum insulation resistance of 5000MΩ. It is available in two configurations: vertical and horizontal. The vertical version is designed for on-board applications, while the horizontal version is a surface-mount device.

Overall, the UU16LFNP-303 is a reliable and effective choice for reducing EMI and common mode noise in power applications. Its shielded construction and shock and vibration protection makes it suitable for a wide variety of industrial applications.
